Fetchmail 5.0.8 through 6.3.21, when using NTLM authentication in debug mode, allows remote NTLM servers to (1) cause a denial of service (crash and delayed delivery of inbound mail) via a crafted NTLM response that triggers an out-of-bounds read in the base64 decoder, or (2) obtain sensitive information from memory via an NTLM Type 2 message with a crafted Target Name structure, which triggers an out-of-bounds read.

Security readout for executives and security teams

This issue affects fetchmail versions 5.0.8 through 6.3.21 only in a narrow configuration: NTLM authentication with debug mode enabled. A malicious or compromised NTLM mail server could crash fetchmail, delaying inbound mail, or cause limited memory disclosure. No source provided evidence of active exploitation. Exposure is most likely on legacy systems running fetchmail 5.0.8 through 6.3.21 with NTLM authentication and debug logging enabled. Systems not using NTLM, not using debug mode, or not connecting to attacker-controlled NTLM servers have materially lower exposure based on the provided description. Treat this as a targeted legacy-mail risk rather than a broad internet emergency. Prioritize remediation if fetchmail still handles business mail with NTLM and debug mode enabled, because crashes can delay mail delivery and memory disclosure could expose sensitive process data. Mitigation focus: Check vendor and distribution advisories for the corrected fetchmail package.; Upgrade fetchmail away from versions 5.0.8 through 6.3.21 where applicable.; Disable fetchmail debug mode when using NTLM authentication..
