A flaw was found in the exsltFuncResultComp() function of libxslt, which handles EXSLT <func:result> elements during stylesheet parsing. Due to improper type handling, the function may treat an XML document node as a regular XML element node, resulting in a type confusion. This can cause unexpected memory reads and potential crashes. While difficult to exploit, the flaw could lead to application instability or denial of service.

The remote Fedora 43 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-84be018d47 advisory.

    Backport fix for CVE-2025-11731 and proposed fix for CVE-2025-10911

Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

The remote Fedora 42 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2026-00347cea5e advisory.

    Backport fix for CVE-2025-11731 and proposed fix for CVE-2025-10911

Tenable has extracted the preceding description block directly from the Fedora security advisory.

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

According to its self-reported version, the Tenable Nessus application running on the remote host is 10.8.0 prior or equal to 10.8.6, 10.9.0 prior to 10.9.6, 10.10.0 prior or equal to 10.10.1 and 10.11.0 prior to 10.11.1. It is, therefore, affected by multiple vulnerabilities as referenced in the TNS-2025-24 advisory.

  - xsltGetInheritedNsList in libxslt before 1.1.43 has a use-after-free issue related to exclusion of result     prefixes. (CVE-2024-55549)

  - A use-after-free vulnerability was found in libxml2. This issue occurs when parsing XPath elements under     certain circumstances when the XML schematron has the <sch:name path=.../> schema elements. This flaw     allows a malicious actor to craft a malicious XML document used as input for libxml, resulting in the     program's crash using libxml or other possible undefined behaviors. (CVE-2025-49794)

  - A vulnerability was found in libxml2. Processing certain sch:name elements from the input XML file can     trigger a memory corruption issue. This flaw allows an attacker to craft a malicious XML input file that     can lead libxml to crash, resulting in a denial of service or other possible undefined behavior due to     sensitive data being corrupted in memory. (CVE-2025-49796)

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

The version of libxslt installed on the remote host is prior to 1.1.44. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2025-332-01 advisory.

    New libxslt packages are available for Slackware 15.0 and -current to fix security issues.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - A flaw was found in the exsltFuncResultComp() function of libxslt, which handles EXSLT <func:result>     elements during stylesheet parsing. Due to improper type handling, the function may treat an XML document     node as a regular XML element node, resulting in a type confusion. This can cause unexpected memory reads     and potential crashes. While difficult to exploit, the flaw could lead to application instability or     denial of service. (CVE-2025-11731)

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