Summary
Red Hat Security Advisory: mingw-glib2 security update

Notes

Topic
An update for mingw-glib2 is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Low. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
GLib provides the core application building blocks for libraries and applications written in C. It provides the core object system used in GNOME, the main loop implementation, and a large set of utility functions for strings and common data structures. Security Fix(es): * glib: GVariant offset table entry size is not checked in is_normal() (CVE-2023-29499) * glib: g_variant_byteswap() can take a long time with some non-normal inputs (CVE-2023-32611) * glib: Timeout in fuzz_variant_text (CVE-2023-32636) * glib: GVariant deserialisation does not match spec for non-normal data (CVE-2023-32665) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section. Additional Changes: For detailed information on changes in this release, see the Red Hat Enterprise Linux 9.4 Release Notes linked from the References section.

While a remote attack is possible if the application is configured to read GVariants over a network connection, this is not the default configuration which makes the likelihood low.
