May 12, 2026
New expat packages are available for Slackware 15.0 and -current to fix a security issue.
Summary
Here are the details from the Slackware 15.0 ChangeLog: patches/packages/expat-2.7.5-i586-2_slack15.0.txz: Rebuilt. This update fixes a security issue: Fix quadratic runtime from attribute name collision checks that allowed denial of service attacks through moderately sized crafted XML input (CWE-407). Please note that a layer of compression around XML can significantly reduce the minimum attack payload size. For more information, see: https://www.cve.org/CVERecord?id=CVE-2026-45186 (* Security fix *)
