Fedora 44 perl-HTML-Gumbo Critical Information Disclosure 2026-75010c7f44

Dist Fedora Esm H88
Heap memory exposure issue in perl-HTML-Gumbo leads to potential information disclosure in Fedora 44. Update recommended.
This package provides the Perl module HTML::Gumbo

Summary

Gumbo is an implementation of the HTML5 parsing algorithm implemented as a

pure C99 library with no outside dependencies.

Update Information:

This package provides the Perl module HTML::Gumbo. Versions before 0.19 disclose heap memory via type confusion. Support for the element was added to libgumbo 0.10.0 in 2015, but the walk_tree function in lib/HTML/Gumbo.xs was not updated to support it. The element was treated as a text-node, where strlen() over-reads the heap block that the pointer addresses.
