CVE-2025-49506
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.
CVE-2026-32327
A bug in APR-util version 1.6.3 (and earlier) allows a stack recursion attack against any library consumer which parses XML from untrusted sources and uses the apr_xml_quote_elem() function. Users are recommended to upgrade to version 1.6.4, which fixes this issue.
CVE-2026-34501
Heap-based Buffer Overflow vulnerability in Apache Portable Runtime Utility redis client. This issue affects Apache Portable Runtime Utility: from 1.6.0 through 1.6.3. Users are recommended to upgrade to version 1.6.4, which fixes the issue.
CVE-2026-34502
Heap-based Buffer Overflow vulnerability in Apache Portable Runtime Utility memcached client This issue affects Apache Portable Runtime Utility: from 1.3.0 through 1.6.3.
