"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)

    Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in
    Apache Portable Runtime Utility via apr_dbd_oracle provider.

    This issue affects Apache Portable Runtime Utility: from 1.6.0 through 1.6.3(CVE-2026-34191)

    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.(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.");
