python3-ldap: python-ldap is a lightweight directory access protocol (LDAP) client APIfor Python
CVE-2025-61912 is fixed in 4 products on 1 platform, first by python-ldap 3.0.0-1ubuntu0.2+esm1, released October 10, 2025. It is not reported as exploited. Patch Radar priority: Routine.
python-ldap is a lightweight directory access protocol (LDAP) client APIfor Python. In versions prior to 3.4.5, ldap.dn.escape_dn_chars() escapes\x00 incorrectly by emitting a backslash followed by a literal NUL byteinstead of the RFC-4514 hex form \00. Any application that uses this helperto construct DNs from untrusted input can be made to consistently failbefore a request is sent to the LDAP server (e.g., AD), resulting in aclient-side denial of service. Version 3.4.5 contains a patch for theissue.
