Fedora 42 glibc Addresses Low Threat Regcomp Vulnerability CVE-2025-8058

Calendar Grey July 27, 2025
Dist Fedora Esm H88
The Fedora 42 release has introduced an update that resolves CVE-2025-8058, addressing a minor vulnerability in the glibc's regcomp functionality as well as in iconv.
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. It also includes a fix for the iconv; it no longer creates executable files.
