The sdump function in sdump.c in fetchmail 6.3.11, 6.3.12, and 6.3.13, when running in verbose mode on platforms for which char is signed, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via an SSL X.509 certificate containing non-printable characters with the high bit set, which triggers a heap-based buffer overflow during escaping.

Security readout for executives and security teams

This is a legacy fetchmail flaw where specific SSL certificate contents can crash the program, and the source says code execution may be possible. Risk depends on running affected 6.3.x versions in verbose mode on signed-char platforms. Exposure is most likely in legacy systems still running affected fetchmail versions with verbose logging enabled. The reachable input is an SSL X.509 certificate from a remote mail endpoint. Treat as a targeted legacy remediation item. It is not KEV-listed, but the potential memory corruption impact justifies prompt action where affected fetchmail versions remain in use. Mitigation focus: Inventory systems for fetchmail 6.3.11, 6.3.12, and 6.3.13.; Upgrade fetchmail through vendor or OS package guidance.; Avoid verbose mode in production while assessing exposure..
