overflow may lead to a crash or possibly\nattacker controlled code execution or other undefined behaviour.\n\nIn ASN1_mbstring_copy() and ASN1_mbstring_ncopy() the destination\nsize for Unicode output is computed in a signed int: by left shift\nof the input character count for BMPSTRING (UTF-16) and\nUNIVERSALSTRING (UTF-32), and by summing per-character byte counts\nfor UTF8STRING. The calculation overflows when the input reaches\naround 2^30 characters. In the worst case (UNIVERSALSTRING at 2^30\ncharacters) the size wraps to zero, OPENSSL_malloc(1) is called, and\nthe subsequent character copy writes several gigabytes past the\none-byte allocation.\n\nX.509 certificate processing routes through ASN1_STRING_set_by_NID(),\nwhose DIRSTRING_TYPE mask excludes UNIVERSALSTRING and whose per-NID\nsize limits cap the input length; no network protocol or\ncertificate-handling path in OpenSSL exercises the overflow.\nTriggering the bug requires an application that calls\nASN1_mbstring_copy() or ASN1_mbstring_ncopy() directly, or registers\na custom string type via ASN1_STRING_TABLE_add(), with\nattacker-controlled input on the order of half a gigabyte or more.\nFor these reasons this issue was assigned Low severity.\n\nThe FIPS modules in 4.0, 3.6, 3.5, 3.4 and 3.0 are not affected by\nthis issue, as the affected code is outside the OpenSSL FIPS module\nboundary.", "title": "Vulnerability description" }, { "category": "general", "text": "The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.", "title": "CVSS score applicability" } ], "product_status": { "known_affected": [ "Debian-11:libssl-dev-0:1.1.1w-0+deb11u8+tuxcare.els1.amd64", "Debian-11:libssl-dev-0:1.1.1w-0+deb11u8+tuxcare.els1.arm64", "Debian-11:libssl-dev-0:1.1.1w-0+deb11u8+tuxcare.els1.armel", "Debian-11:libssl-dev-0:1.1.1w-0+deb11u8.amd64", "Debian-11:libssl-dev-0:1.1.1w-0+deb11u8.arm64", "Debian-11:libssl-dev-0:1.1.1w-0+deb11u8.armel", "Debian-11:libssl-doc-0:1.1.1w-0+deb11u8+tuxcare.els1.all", "Debian-11:libssl-doc-0:1.1.1w-0+deb11u8.all", "Debian-11:libssl1.1-0:1.1.1w-0+deb11u8+tuxcare.els1.amd64", "Debian-11:libssl1.1-0:1.1.1w-0+deb11u8+tuxcare.els1.arm64", "Debian-11:libssl1.1-0:1.1.1w-0+deb11u8+tuxcare.els1.armel", "Debian-11:libssl1.1-0:1.1.1w-0+deb11u8.amd64", "Debian-11:libssl1.1-0:1.1.1w-0+deb11u8.arm64", "Debian-11:libssl1.1-0:1.1.1w-0+deb11u8.armel", "Debian-11:openssl-0:1.1.1w-0+deb11u8+tuxcare.els1.amd64", "Debian-11:openssl-0:1.1.1w-0+deb11u8+tuxcare.els1.arm64", "Debian-11:openssl-0:1.1.1w-0+deb11u8+tuxcare.els1.armel", "Debian-11:openssl-0:1.1.1w-0+deb11u8.amd64", "Debian-11:openssl-0:1.1.1w-0+deb11u8.arm64", "Debian-11:openssl-0:1.1.1w-0+deb11u8.armel" ] }, "references": [ { "category": "self", "summary": "Canonical URL", "url": "https://cve.tuxcare.com/els/cve/CVE-2026-7383" }, { "category": "external", "summary": "https://github.com/openssl/openssl/commit/4f8d2bddaa2c8e06f9c33390ee1717059a6e4be6", "url": "https://github.com/openssl/openssl/commit/4f8d2bddaa2c8e06f9c33390ee1717059a6e4be6" }, { "category": "external", "summary": "https://github.com/openssl/openssl/commit/80c15faaf78042bbb8654a0e234c50c381732f74", "url": "https://github.com/openssl/openssl/commit/80c15faaf78042bbb8654a0e234c50c381732f74" }, { "category": "external", "summary": "https://github.com/openssl/openssl/commit/bd17511070fb39a67bfa19682affb765e706a974", "url": "https://github.com/openssl/openssl/commit/bd17511070fb39a67bfa19682affb765e706a974" }, { "category": "external", "summary": "https://github.com/openssl/openssl/commit/c332adaced43bcbb85f97410597e951c11ec3083", "url": "https://github.com/openssl/openssl/commit/c332adaced43bcbb85f97410597e951c11ec3083" }, { "category": "external", "summary": "https://github.com/openssl/openssl/commit/d32350ae8ef7426718f5aa9e383d4b51398ee255", "url": "https://github.com/openssl/openssl/commit/d32350ae8ef7426718f5aa9e383d4b51398ee255" }, { "category": "external", "summary": "https://openssl-library.org/news/secadv/20260609.txt", "url": "https://openssl-library.org/news/secadv/20260609.txt" } ], "release_date": "2026-06-09T17:17:00Z", "remediations": [ { "category": "no_fix_planned", "date": "2026-09-01T14:20:14.818015Z", "details": "This overflow is only reachable when an application directly calls ASN1_mbstring_copy()/ASN1_mbstring_ncopy() or registers a custom ASN.1 string type, and it requires attacker-controlled input of roughly 2^30 characters (~0.5 GB) to trigger; OpenSSL’s standard X.509/certificate-processing path excludes UNIVERSALSTRING and enforces per‑NID size limits, so normal TLS/certificate handling does not exercise the bug.
