Echo: libxml-libxml-perl: security update to 2.0207+dfsg+really+2.0134-5+e1

high Tenable Cloud Security Plugin ID 463618

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)

Solution

Update the libxml-libxml-perl library and its related packages to version 2.0207+dfsg+really+2.0134-5+e1 or later.
