Updates test_embedded_header_via_string_rejected to expect HeaderWriteError instead of HeaderParseError. In Python 2.7 this single Generator-class hardening covers both upstream CVE-2026-1299 (BytesGenerator) and CVE-2024-6923 because BytesGenerator does not exist in 2.7. - CVE-2026-1299 * SECURITY UPDATE: missing header-name newline check in email.Generator - debian/patches/CVE-2024-6923.patch: add NEWLINE_WITHOUT_FWSP check on the header *name* at the top of Generator._write_headers() in Lib/email/generator.py, raising HeaderWriteError when a CR/LF without folding whitespace is found in the header name. Documents HeaderWriteError in Doc/library/email.errors.rst and adds a test_invalid_header_format regression test in Lib/email/test/test_email_renamed.py. - CVE-2024-6923 * SECURITY UPDATE: ssl.SSLContext data race in cert_store_stats / get_ca_certs - debian/patches/CVE-2024-0397.patch: backport of upstream 3.8 commit 29c97287d2 ("[3.8] gh-114572: Fix locking in cert_store_stats and get_ca_certs"). Adds a polyfill of OpenSSL 3.3's X509_STORE_get1_objects() (deep-copy under X509_STORE_lock()) and replaces the shared, unlocked X509_STORE_get0_objects() calls in cert_store_stats() and get_ca_certs() in Modules/_ssl.c, preventing a memory race and potential use-after-free when an SSLContext is shared across multiple threads. - CVE-2024-0397 * SECURITY UPDATE: open redirect in BaseHTTPServer when path starts with // - debian/patches/CVE-2021-28861.patch: backport of upstream commit 4abab6b603 ("gh-87389: Fix an open redirection vulnerability in http.server"). In Lib/BaseHTTPServer.py, after the request line is parsed, collapse any leading run of '/' characters to a single '/' so an attacker-controlled '//evil.example/...' path cannot become an absolute scheme-less URI in a 301 Location header. Adds a regression test in Lib/test/test_httpservers.py. - CVE-2021-28861 Important TuxCare License Agreement CVE-2024-6923 CVE-2021-28861 CVE-2024-0397 CVE-2026-1299 Debian 13 * SECURITY UPDATE: email BytesGenerator header injection - debian/patches/CVE-2026-1299.patch: combined backport of gh-121650 (CVE-2024-6923) and gh-144125 (CVE-2026-1299) that adds email.errors.HeaderWriteError, the policy.verify_generated_headers attribute, and the verify-on-write check for both Generator and BytesGenerator, preventing CRLF/LF header injection through custom fold(). - CVE-2026-1299 * SECURITY UPDATE: ssl.SSLContext memory race in cert_store_stats / get_ca_certs - debian/patches/CVE-2024-0397.patch: backport the X509_STORE_get1_objects shim and the x509_object_dup helper from cpython 3.8.20 (29c97287d2). The two affected impl functions in Modules/_ssl.c (cert_store_stats / get_ca_certs) now take a deep-copy snapshot of the X509_STORE under X509_STORE_lock(), preventing the use-after-free that occurred when certificates were loaded concurrently from another thread. - CVE-2024-0397 * SECURITY UPDATE: ipaddress is_private/is_global misclassification - debian/patches/CVE-2024-4032.patch: backport cpython 3.8.20 fix 895f7e2ac2 (gh-113171). Adds the _IPv4Constants._private_networks_exceptions list (192.0.0.9/32, 192.0.0.10/32) and the IPv6 equivalents (2001:1::1/128, 2001:1::2/128, 2001:3::/32, 2001:4:112::/48, 2001:20::/28, 2001:30::/28). Expands 192.0.0.0/29 to /24, adds 64:ff9b:1::/48 and 2002::/16 to the IPv6 _private_networks list, and updates is_private to filter against the exceptions list and use ipv4_mapped semantics on IPv6. - CVE-2024-4032 Important TuxCare License Agreement CVE-2024-4032 CVE-2024-0397 CVE-2026-1299 Debian 13 * SECURITY UPDATE: email BytesGenerator header injection - debian/patches/CVE-2026-1299.patch: verify generated headers in email.generator.BytesGenerator and Generator. Adds the HeaderWriteError exception, NEWLINE_WITHOUT_FWSP / NEWLINE_WITHOUT_FWSP_BYTES regexes, and the Policy.verify_generated_headers attribute, then raises HeaderWriteError when the folded header does not end with the policy linesep or contains a stray newline. Includes the CVE-2024-6923 prerequisite hardening of the string Generator. - CVE-2026-1299 * SECURITY UPDATE: ssl.SSLContext memory race in cert_store_stats / get_ca_certs - debian/patches/CVE-2024-0397.patch: backport the upstream X509_STORE_get1_objects shim and the x509_object_dup helper from cpython 29c97287d205bf2f410f4895ebce3f43b5160524, then switch _ssl__SSLContext_cert_store_stats_impl and _ssl__SSLContext_get_ca_certs_impl to take a deep-copy snapshot of the X509_STORE under lock, freeing the snapshot before returning. Closes a use-after-free triggered by loading certificates concurrently from another thread. - CVE-2024-0397 * SECURITY UPDATE: ipaddress is_private / is_global misclassification - debian/patches/CVE-2024-4032.patch: backport upstream gh-113171 / gh-65056. Update Lib/ipaddress.py to align the _private_networks lists with the IANA special-purpose registries and add _private_networks_exceptions so that is_private / is_global no longer misclassify addresses in 192.0.0.0/24 (with 192.0.0.9 and 192.0.0.10 exceptions), 64:ff9b:1::/48, 2002::/16, and the 2001::/23 sub-range exceptions (2001:1::1, 2001:1::2, 2001:3::/32, 2001:4:112::/48, 2001:20::/28, 2001:30::/28).

This is a bypass of CVE-2024-6923, which only added the validation to the text Generator class. - debian/patches/CVE-2026-1299.patch: mirror the verify_generated_headers / NEWLINE_WITHOUT_FWSP check from Generator._write_headers into BytesGenerator._write_headers in Lib/email/generator.py, raising HeaderWriteError on unsafely folded or delimited headers; extend test_email tests to cover message.as_bytes(). - CVE-2026-1299 Important TuxCare License Agreement CVE-2026-1299 Debian 13 * SECURITY UPDATE: email.generator.BytesGenerator does not validate folded headers, allowing header injection via crafted Header subclasses - debian/patches/CVE-2026-1299.patch: extend verify_generated_headers check to BytesGenerator._write_headers() in Lib/email/generator.py so unsafely folded or delimited headers raise HeaderWriteError on as_bytes() too. Adds matching test coverage in Lib/test/test_email/test_generator.py and test_policy.py. - CVE-2026-1299 Important TuxCare License Agreement CVE-2026-1299 Debian 13 * SECURITY UPDATE: binascii.a2b_base64 / base64.b64decode stop decoding after the first padded quad, silently dropping any excess data.

The CPython side and the libexpat side of the fix are paired -- the new XML_SetHashSalt16Bytes call sites are inert unless the linked libexpat exposes the 16-byte salt API. Because alt-python37 statically links the bundled Modules/expat/ tree (libexpat 2.5.0), we backport both halves here. - debian/patches/CVE-2026-7210.patch: backport of cpython 24b8f12544 (gh-149018, Stan Ulbrych). Adds the XML_SetHashSalt16Bytes function pointer to the pyexpat CAPI and uses it with 16 bytes of entropy in pyexpat.c and _elementtree.c when the 16-byte salt API is available; falls back to legacy XML_SetHashSalt otherwise. The original upstream conditional only checks XML_COMBINED_VERSION >= 20800; we widen it to also activate when the feature-test macro XML_HAS_SET_HASH_SALT_16_BYTES is defined, which our bundled expat patch exposes (see CVE-2026-41080.patch). On builds that use system libexpat (--with-system-expat, e.g. Alpine), the macro is absent and the version check still applies normally. - debian/patches/CVE-2026-41080.patch: backport of libexpat PR #1183 (https://github.com/libexpat/libexpat/pull/1183), restricted to the C sources needed for the bundled static link (Modules/expat/expat.h, internal.h, xmlparse.c). Widens the per-parser salt storage to a full struct sipkey (128 bits) and adds XML_SetHashSalt16Bytes. Also defines the alt-python- specific feature-test macro XML_HAS_SET_HASH_SALT_16_BYTES so the CPython side can detect the backported API without bumping XML_COMBINED_VERSION (the bundled tree still reports 2.5.0). Together with CVE-2026-7210 this activates the 16-byte salt path inside pyexpat / xml.etree against the bundled expat, restoring proper hash-flood mitigation. - CVE-2026-7210 - CVE-2026-41080 Critical TuxCare License Agreement CVE-2026-7210 Debian 13 * SECURITY UPDATE: CVE-2026-7210 + CVE-2026-41080 (paired): backport the libexpat 16-byte salt API (XML_SetHashSalt16Bytes) into bundled expat 2.2.8 and wire pyexpat/_elementtree to use it. Together these restore proper hash-flood mitigation. xml.parsers.expat and xml.etree.ElementTree previously used only the legacy 8-byte XML_SetHashSalt API; that salt is brute-forceable with modern hardware, allowing a crafted XML document to trigger hash collisions and a denial of service. - debian/patches/CVE-2026-7210.patch: backport of cpython 24b8f12544 (gh-149018, Stan Ulbrych). Switches pyexpat and _elementtree to XML_SetHashSalt16Bytes when built/linked against libexpat >= 2.8.0, falling back to the legacy XML_SetHashSalt on older expat. Adds a hashsalt16[16] field to _Py_HashSecret_t in Include/object.h (seeded by _PyRandom_Init alongside prefix / suffix) and a NULL-able SetHashSalt16Bytes function pointer in the pyexpat CAPI struct so _elementtree can dispatch at runtime. No upstream backport to 2.7 exists; upstream backports landed only to 3.14 / 3.15. - debian/patches/CVE-2026-41080.patch: backport of libexpat PR #1183 into the bundled Modules/expat/ tree (libexpat 2.2.8). Widens m_hash_secret_salt from `unsigned long` to a 128-bit `struct sipkey` and adds the new public XML_SetHashSalt16Bytes() entry point. Since pyexpat.so / _elementtree.so are statically linked against this tree, the cpython half now consumes full 16-byte entropy without requiring an external libexpat >= 2.8.0 at runtime. - CVE-2026-7210 - CVE-2026-41080 Critical TuxCare License Agreement CVE-2026-7210 Debian 13 * SECURITY UPDATE: CVE-2026-7210 + CVE-2026-41080 (paired) — backport the libexpat 16-byte salt API (XML_SetHashSalt16Bytes) into bundled expat 2.4.1 and wire pyexpat/_elementtree to use it. Together these restore proper hash-flood mitigation for xml.parsers.expat and xml.etree.ElementTree. - debian/patches/CVE-2026-7210.patch: backport of cpython 24b8f12544 (gh-149018, Stan Ulbrych). Adds a new 16-byte _Py_HashSecret.expat.hashsalt16 slot in Include/pyhash.h (overlapping the existing padding), extends the PyExpat CAPI in Include/pyexpat.h with SetHashSalt16Bytes, and prefers the new API in Modules/pyexpat.c and Modules/_elementtree.c when built against libexpat exposing it; falls back to the legacy XML_SetHashSalt path otherwise. The two XML_COMBINED_VERSION gates are extended with `|| defined(XML_HAS_HASHSALT16BYTES_BACKPORT)` so the new code path activates against the bundled patched libexpat without bumping its advertised version, while --with-system-expat builds (Alpine) keep the upstream `>= 20800` semantics. - debian/patches/CVE-2026-41080.patch: backport of libexpat PR #1183. Widens the parser's internal hash salt from `unsigned long m_hash_secret_salt` to a full `struct sipkey m_hash_secret_salt_128` (+ an m_hash_secret_salt_set flag), adds the new XML_SetHashSalt16Bytes API and the matching XML_HAS_HASHSALT16BYTES_BACKPORT marker in expat.h, and namespaces the new symbol via pyexpatns.h. Applied to bundled Modules/expat/; on Alpine `prepare()` deletes Modules/expat after the patch, so the libexpat backport is a no-op there and the system libexpat decides whether the new API is available. - CVE-2026-7210 - CVE-2026-41080 Critical TuxCare License Agreement CVE-2026-7210 Debian 13 * SECURITY UPDATE: xml.parsers.expat and xml.etree.ElementTree used insufficient entropy for the Expat hash-flooding salt (only the 8-byte Py_hash_t field _Py_HashSecret.expat.hashsalt was passed to XML_SetHashSalt), allowing a crafted XML document to trigger hash flooding in Expat's internal hash tables. Full mitigation requires libexpat 2.8.0+ at runtime (or a distro-backported equivalent that exports XML_SetHashSalt16Bytes). - debian/patches/CVE-2026-7210.patch: backport of cpython 24b8f12544 (gh-149018, Stan Ulbrych). Adds a 16-byte hashsalt16 field to _Py_HashSecret.expat and prefers the new XML_SetHashSalt16Bytes API in both Modules/pyexpat.c (newxmlparseobject + capi export) and Modules/_elementtree.c (XMLParser.__init__); the legacy XML_SetHashSalt path is kept as fallback when the loaded libexpat does not export the new symbol. The symbol is declared __attribute__((weak)) in Modules/pyexpat.c so the same source path works whether the build links against bundled libexpat 2.8.0+ or a distro libexpat 2.5/2.7 that backports the entropy fix without bumping XML_COMBINED_VERSION (Debian, Ubuntu, RHEL/CL, Alpine). - CVE-2026-7210 Critical TuxCare License Agreement CVE-2026-7210 Debian 13 * SECURITY UPDATE: xml.parsers.expat / xml.etree.ElementTree used insufficient entropy for libexpat hash-flooding protection, allowing a crafted XML document to trigger hash collisions. Mitigation requires both libexpat 2.8.0+ (or a distro-backported equivalent that exports XML_SetHashSalt16Bytes) and a Python-side patch to seed the parser with the new 16-byte salt API. - debian/patches/CVE-2026-7210.patch: backport of cpython 24b8f12544 (gh-149018, Stan Ulbrych). pyexpat and _elementtree call XML_SetHashSalt16Bytes with _Py_HashSecret.expat.hashsalt16 (16 bytes of entropy); legacy XML_SetHashSalt remains as the fallback when the loaded libexpat does not export the new symbol. The symbol is declared __attribute__((weak)) in Modules/pyexpat.c so the same source path works whether the build links against bundled libexpat 2.8.0+ or a distro libexpat 2.5/2.7 that backports the entropy fix without bumping XML_COMBINED_VERSION (Debian, Ubuntu, RHEL/CL, Alpine). Extends the PyExpat CAPI with a nullable SetHashSalt16Bytes slot populated from the weak reference. - CVE-2026-7210 Critical TuxCare License Agreement CVE-2026-7210 Debian 13 * SECURITY UPDATE: tarfile normalized AREGTYPE blocks to DIRTYPE while processing GNU long name/link follow-up headers, allowing a crafted tar archive to be misinterpreted. - debian/patches/CVE-2025-13462.patch: backport of cpython 42d754e34c (gh-141707).

Declares XML_SetHashSalt16Bytes as __attribute__((weak)) at the top of Modules/pyexpat.c and replaces the compile-time XML_COMBINED_VERSION / XML_HAS_SET_HASH_SALT_16_BYTES gate with a single runtime "if (... != NULL)" check at every call site (newxmlparseobject in pyexpat.c, the pyexpat C-API capsule init, and _elementtree.c). RPM / Debian builds keep 16-byte mitigation via bundled libexpat 2.5.0 + CVE-2026-41080; Alpine activates the 16-byte path automatically the moment the system libexpat ships the entropy fix; libexpat without the symbol falls back to the legacy 8-byte XML_SetHashSalt path (no regression). - CVE-2026-41080.patch is unchanged. - CVE-2026-7210 * SECURITY UPDATE: urllib.parse.urlsplit / urlparse accepted bracketed hosts that were not valid IPv6 / IPvFuture, enabling SSRF and parser-differential attacks. - debian/patches/CVE-2024-11168.patch: backport of cpython 3.11 b2171a2 (gh-103848, Seth Larson). - CVE-2024-11168 * SECURITY UPDATE: bundled libexpat 2.5.0 crashes in XML_ResumeParser when XML_StopParser is called on an unstarted parser (NULL deref). - debian/patches/CVE-2024-50602.patch: backport of libexpat 51c70190 (PR #915).
