Package        : glib2.0
CVE ID         : CVE-2024-34397

Alicia Boya Garcia reported that the GDBus signal subscriptions in the
GLib library are prone to a spoofing vulnerability. A local attacker can
take advantage of this flaw to cause a GDBus-based client to behave
incorrectly, with an application-dependent impact.

gnome-shell is updated along with this update to avoid a screencast
regression after fixing CVE-2024-34397.

For the oldstable distribution (bullseye), this problem has been fixed
in version 2.66.8-1+deb11u2.

For the stable distribution (bookworm), this problem has been fixed in
version 2.74.6-2+deb12u1.

We recommend that you upgrade your glib2.0 packages.

For the detailed security status of glib2.0 please refer to its security
tracker page at:
