{"id":"AZL-112741","summary":"CVE-2026-100407 affecting package git 2.45.4-3","details":"Git for Windows is the Windows port of Git. From 2.44.0.windows.1 until 2.55.0.windows.3, the git-credential-wincred store operation in contrib/credential/wincred/git-credential-wincred.c uses _scwprintf() to size a formatted wide-character credential buffer without space for the terminating NUL when both password and oauth_refresh_token are present. The operation also passes a byte count to _snwprintf_s() where a wide-character count is required, allowing the terminator to be written one WCHAR past the heap allocation before CredWriteW() persists the credential. The resulting fixed two-byte NUL overwrite can terminate the helper with Windows heap-corruption status and can cause git credential approve to report success even though the OAuth credential was not stored. This issue is fixed in version 2.55.0.windows.3.","modified":"2026-11-07T14:18:05.074668854Z","published":"2026-11-04T15:17:21Z","upstream":["CVE-2026-100407"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-100407"}],"affected":[{"package":{"name":"git","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/git"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.45.4-3"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-112741.json"}}],"schema_version":"1.9.2"}
