Uncontrolled recursion in XPath evaluation in libxml2 up to and including version 2.9.14 allows a local attacker to cause a stack overflow via crafted expressions. XPath processing functions `xmlXPathRunEval`, `xmlXPathCtxtCompile`, and `xmlXPathEvalExpr` were resetting recursion depth to zero before making potentially recursive calls. When such functions were called recursively this could allow for uncontrolled recursion and lead to a stack overflow. These functions now preserve recursion depth across recursive calls, allowing recursion depth to be controlled.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-991295 advisory.

    Package        : libxml2     Version        : 2.9.10+dfsg-6.7+deb11u9     CVE ID         : CVE-2025-9714 CVE-2025-7425     Debian Bug     : 1109122

    Two security issues were found in libxml2, the GNOME XML library, which     could yield denial of service or heap corruption.

    CVE-2025-9714

        It was discovered that recursion evaluation in XPath evaluation is         uncontrolled and therefore allows a local attacker to cause a stack         overflow via crafted expressions.

    CVE-2025-7425

        Sergei Glazunov discovered a heap-use-after-free in xmlFreeID()         caused by `atype` corruption.  While the vulnerability was reported         against libxslt, the XSLT 1.0 processing library, it is now         mitigated in this libxml2 version.

    For Debian 11 bullseye, this problem has been fixed in version     2.9.10+dfsg-6.7+deb11u9.

    We recommend that you upgrade your libxml2 packages.

    For the detailed security status of libxml2 please refer to     its security tracker page at:

Note that Nessus relies on the presence of the package as reported by the vendor.
