  • apport - automatically generate crash reports for debugging

Details

It was discovered that Apport could be tricked into writing core files as
root into arbitrary directories in certain scenarios. A local attacker
could possibly use this issue to escalate privileges. This update will
cause Apport to generate all core files in the /var/lib/apport/coredump
directory.

Update instructions

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

Ubuntu 21.10
Ubuntu 21.04
Ubuntu 20.04
Ubuntu 18.04

In general, a standard system update will make all the necessary changes.
