Hi, The following vulnerability was published for python-ldap. CVE-2025-61912[0]: | python-ldap is a lightweight directory access protocol (LDAP) client | API for 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 byte instead of the RFC-4514 hex | form \00. Any application that uses this helper to construct DNs | from untrusted input can be made to consistently fail before a | request is sent to the LDAP server (e.g., AD), resulting in a | client-side denial of service. Version 3.4.5 contains a patch for | the issue. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
