{"id":"AZL-112403","summary":"CVE-2026-118767 affecting package botan2 2.14.0-2","details":"Botan is a C++ cryptography library. From 1.11.22 until 3.13.0, Botan's Python binding converted Python strings containing U+0000 to const char* values without consistently rejecting the embedded NUL, causing bcrypt and check_bcrypt to process only the prefix before the NUL. Applications could validate a longer password but hash a shorter effective value, allowing application password-policy bypass; scrypt and argon2 are unaffected. This issue is fixed in version 3.13.0.","modified":"2026-11-02T14:18:11.791600583Z","published":"2026-10-29T18:17:28Z","upstream":["CVE-2026-118767"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-118767"}],"affected":[{"package":{"name":"botan2","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/botan2"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"2.14.0-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-112403.json"}}],"schema_version":"1.9.2"}
