EulerOS 2.0 SP11 : perl-XML-LibXML (EulerOS-SA-2026-4273)

high Nessus Plugin ID 364923

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the perl-XML-LibXML package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 XML::LibXML versions through 2.0210 for Perl read out-of-bounds heap memory when parsing XML node names containing truncated UTF-8 byte sequences.

 A node name ending in the middle of a multi byte UTF-8 sequence causes the parser to read past the end of the input string into adjacent heap memory.

 Any Perl process that passes attacker controlled strings to XML::LibXML's DOM node-name methods can reach this path on the default API. The likely consequence is a crash, causing denial of service.(CVE-2026-8177)

Tenable has extracted the preceding description block directly from the EulerOS perl-XML-LibXML security advisory.

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

Solution

Update the affected perl-XML-LibXML packages.
