==========================================================================
Ubuntu Security Notice USN-6899-1
July 16, 2024

gtk+2.0, gtk+3.0 vulnerability
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 24.04 LTS
- Ubuntu 22.04 LTS
- Ubuntu 20.04 LTS

Summary:

GTK could be made to run programs from the current directory.

Software Description:
- gtk+2.0: GTK graphical user interface library
- gtk+3.0: GTK graphical user interface library

Details:

It was discovered that GTK would attempt to load modules from the current
directory, contrary to expectations. If users started GTK applications from
shared directories, a local attacker could use this issue to execute
arbitrary code, and possibly escalate privileges.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 24.04 LTS
   libgail-3-0t64                  3.24.41-4ubuntu1.1
   libgtk2.0-0t64                  2.24.33-4ubuntu1.1

Ubuntu 22.04 LTS
   libgtk-3-0                      3.24.33-1ubuntu2.2
   libgtk2.0-0                     2.24.33-2ubuntu2.1

Ubuntu 20.04 LTS
   libgtk-3-0                      3.24.20-0ubuntu1.2
   libgtk2.0-0                     2.24.32-4ubuntu4.1

After a standard system update you need to restart your session to make all
the necessary changes.
