Description

According to the versions of the apr-util packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

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-2025-49506)

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-2026-34501)

This issue affects Apache Portable Runtime Utility: from 1.3.0 through 1.6.3.(CVE-2026-34502)

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.(CVE-2026-32327)

Tenable has extracted the preceding description block directly from the EulerOS apr-util security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
