Buffer overflow in the POP3 client in Fetchmail before 6.2.5.2 allows remote POP3 servers to cause a denial of service and possibly execute arbitrary code via long UIDL responses. NOTE: a typo in an advisory accidentally used the wrong CVE identifier for the Fetchmail issue. This is the correct identifier.

Security readout for executives and security teams

CVE-2005-2335 is a Fetchmail POP3 client buffer overflow. A malicious or compromised POP3 server could send an overly long UIDL response, crashing Fetchmail and possibly running code. The risk matters mainly for legacy systems still using Fetchmail before 6.2.5.2 to pull mail from POP3 servers. Exposure is most likely on older Unix/Linux or macOS systems running Fetchmail as a scheduled mail retrieval client against POP3 servers. Systems using patched vendor packages, Fetchmail 6.2.5.2 or later, or not using POP3 Fetchmail polling are unlikely to be exposed. Treat this as a targeted legacy exposure issue, not a broad internet-facing emergency. Prioritize environments where Fetchmail still pulls mail from third-party or weakly controlled POP3 servers, especially on systems with sensitive mail-handling automation. Mitigation focus: Upgrade Fetchmail to 6.2.5.2 or a vendor-fixed package.; Apply relevant OS vendor advisories for Debian, Red Hat, Fedora, SUSE, or Apple systems.; Disable legacy Fetchmail POP3 polling where it is no longer required..
