Fedora 43 perl-CSS-Minifier-XS Critical Memory Leak Fix CVE-2026-13593

fedora
Calendar Grey July 8, 2026
Dist Fedora Esm H88
Update for perl-CSS-Minifier-XS in Fedora 43 fixes memory leak issue, ensuring better performance and stability.
This package contains the Perl module CSS::Minifier::XS

Summary

'CSS::Minifier::XS' is a CSS "minifier". It's designed to remove

unnecessary white-space and comments from CSS files, while also

*not* breaking the CSS. 'CSS::Minifier::XS' is similar in function

to 'CSS::Minifier', but is substantially faster as it's written

in XS and not just pure Perl.

Update Information:

This package contains the Perl module CSS::Minifier::XS. Versions of the module before 0.14 have a memory leak when the entire document is minified away (CVE-2026-13593). This update brings version 0.15 which fixes this issue.
