Dist Fedora Esm H88
Addresses minor security concern in regcomp method of glibc for Fedora 41, enhancing overall system reliability and protection.
This update fixes CVE-2025-8058, a low-impact security vulnerability in the regcomp function.

Summary

The glibc package contains standard libraries which are used by

multiple programs on the system. In order to save disk space and

memory, as well as to make upgrading easier, common system code is

kept in one place and shared between programs. This particular package

contains the most important sets of shared libraries: the standard C

library and the standard math library. Without these two libraries, a

Linux system will not function.

Update Information:

This update fixes CVE-2025-8058, a low-impact security vulnerability in the regcomp function.
