CVE-2016-9951 (opens in a new tab)How to fix?
Upgrade Ubuntu:14.04 apport to version 2.14.1-0ubuntu3.23 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream apport package and not the apport package as distributed by Ubuntu.
See How to fix? for Ubuntu:14.04 relevant fixed versions and status.
An issue was discovered in Apport before 2.20.4. A malicious Apport crash file can contain a restart command in RespawnCommand or ProcCmdline fields. This command will be executed if a user clicks the Relaunch button on the Apport prompt from the malicious crash file. The fix is to only show the Relaunch button on Apport crash files generated by local systems. The Relaunch button will be hidden when crash files are opened directly in Apport-GTK.
