========================================================================== Ubuntu Security Notice USN-4764-1 March 15, 2021
glib2.0 vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.10 - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS
Summary:
GLib could be made to create files if it opened a specially crafted archive.
Software Description: - glib2.0: GLib library of C routines
Details:
It was discovered that GLib incorrectly handled certain symlinks when replacing files. If a user or automated system were tricked into extracting a specially crafted file with File Roller, a remote attacker could possibly create files outside of the intended directory.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.10: libglib2.0-0 2.66.1-2ubuntu0.2
Ubuntu 20.04 LTS: libglib2.0-0 2.64.6-1~ubuntu20.04.3
Ubuntu 18.04 LTS: libglib2.0-0 2.56.4-0ubuntu0.18.04.8
Ubuntu 16.04 LTS: libglib2.0-0 2.48.2-0ubuntu4.8
In general, a standard system update will make all the necessary changes.
