CVE-2026-8177

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 PUBLISHED

Description (CNA)

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.

A flaw was found in XML::LibXML for Perl. A remote attacker could exploit this vulnerability when processing specially crafted XML node names containing incomplete UTF-8 character sequences. This can lead to an out-of-bounds read in heap memory, potentially causing the application to crash and resulting in a denial of service.
