{"id":"AZL-105066","summary":"CVE-2026-94184 affecting package fetchmail 6.4.39-2","details":"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.","modified":"2026-10-01T14:15:23.308872550Z","published":"2026-09-21T15:17:38Z","upstream":["CVE-2026-94184"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-94184"}],"affected":[{"package":{"name":"fetchmail","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/fetchmail"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.4.39-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-105066.json"}}],"schema_version":"1.9.0"}
