Red Hat Security Advisory: glib2 security update
Two security vulnerabilities have been identified in the GLib library used by Red Hat Enterprise Linux 10 and related products. These include a buffer overflow in the set_connect_msg() function (CVE-2024-52533) and a buffer underflow in the g_string_insert_unichar function (CVE-2025-4373). Both vulnerabilities affect core GLib components used in C applications and GNOME. Red Hat has issued a security advisory rating the impact as moderate and has released updated packages to address these issues. No known exploits are reported in the wild. Users of affected Red Hat Enterprise Linux 10 versions and related CodeReady Linux Builder products should apply the available updates to remediate these vulnerabilities.
