     apr-util XML stack recursion crash (cve.mitre.org)
     A bug in APR-util version 1.6.3 (and earlier) allows a stack
     recursion attack against any library consumer which parses XML

  *) SECURITY: CVE-2025-49506: apr_password_validate() vulnerable to
     timing attack (cve.mitre.org)
     APR-util versions 1.6.3 (and earlier) function
     apr_password_validate() was not constant-time with regards to
     hashes or passwords comparisons, potentially leaking their
     content via a side channel timing attack particularly on
     platforms without crypt() such as  Windows, BeOS, NetWare, or
     Android.
     Users are recommended to upgrade to version 1.6.4, which fixes
     this issue.
