NVD Description

Note: Versions mentioned in the description apply only to the upstream fetchmailconf package and not the fetchmailconf package as distributed by SLES. See How to fix? for SLES:15.4 relevant fixed versions and status.

A stack-based buffer overflow flaw was found in fetchmail when built with NTLM support. A malicious or compromised mail server advertising NTLM authentication can send a crafted Type 2 challenge that causes fetchmail to write past a fixed stack buffer while building the NTLM authenticate response. This may lead to remote code execution depending on stack-frame layout, or to authentication failure or process termination under memory hardening.
