Apply the official fix by upgrading to GNU C Library version 2.44 or later. Red Hat and Ubuntu have released updated packages that address this vulnerability. Standard system updates will incorporate these fixes, so ensure systems are fully updated to the fixed versions.
Description
A vulnerability in the GNU C Library (glibc) prior to version 2.44 allows an attacker to cause a denial of service due to incorrect memory handling in the wordexp function when called with the WRDE_APPEND flag. This flaw affects Linux and other Unix-based systems that rely on glibc for system calls and basic functionality. The issue has been fixed in version 2.44.
