[CLSA-2026:1781103532] alt-python27: Fix of 2 CVEs
Type:
security
Severity:
Important
Release date:
2026-06-10 14:59:27 UTC
Description:
- CVE-2025-15366: imaplib.IMAP4._command() concatenated each argument into the wire-level command without inspecting it, so user-controlled text (e.g. a username passed to IMAP4.login()) containing CR/LF or other control characters could inject a second IMAP command. A module-level _control_chars regex and a guard in _command() now reject any argument containing a byte in [\x00-\x1F\x7F] with ValueError before concatenation. - CVE-2025-15367: poplib.POP3._putcmd() sent its argument to the server without inspecting it, so user-controlled text passed to user()/pass_()/apop()/rpop()/top() could inject a second POP3 command. _putcmd() now rejects any argument containing a byte in [\x00-\x1F\x7F] with ValueError before sending.
