Oct 1 RESCORED — CVE-2026-94184 (Red Hat Enterprise Linux 10). CVSS 8.1 → 5.3 (NVD).
Description
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.
