- Ubuntu 22.04 LTS
Summary:
Several security issues were fixed in GLib.
Software Description:
- glib2.0: GLib library of C routines
Details:
It was discovered that GLib incorrectly handled escaping URI strings. An
attacker could use this issue to cause GLib to crash, resulting in a
denial of service, or possibly execute arbitrary code. (CVE-2025-13601)
It was discovered that GLib incorrectly parsed certain GVariants. An
attacker could use this issue to cause GLib to crash, resulting in a
denial of service, or possibly execute arbitrary code. (CVE-2025-14087)
It was discovered that GLib incorrectly parsed certain long invalid ISO
8601 timestamps. An attacker could possibly use this issue to cause GLib to
crash, resulting in a denial of service. This issue only affected Ubuntu
22.04 LTS and Ubuntu 24.04 LTS. (CVE-2025-3360)
It was discovered that GLib incorrectly handled GString memory operations.
An attacker could use this issue to cause GLib to crash, resulting in a
denial of service, or possibly execute arbitrary code. This issue only
affected Ubuntu 24.04 LTS and Ubuntu 25.04. (CVE-2025-6052)
It was discovered that GLib incorrectly handled creating temporary files.
An attacker could possibly use this issue to access unauthorized data. This
issue only affected Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 25.04.
(CVE-2025-7039)

After a standard system update you need to reboot your computer to make
all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed.
Unless you manually uninstalled the standard kernel metapackages
(e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual,
linux-powerpc), a standard system upgrade will automatically perform
this as well.
