First published: Mon Nov 04 2019(Updated: )
USN-4171-1 fixed several vulnerabilities in apport. This update provides the corresponding update for Ubuntu 14.04 ESM.

This could be used by a local attacker to possibly crash Apport or have other unspecified consequences. (CVE-2019-11481) Sander Bos discovered a race-condition in Apport during core dump creation. This could be used by a local attacker to generate a crash report for a privileged process that is readable by an unprivileged user.

This could be used by a local attacker to generate a crash report for a privileged process that is readable by an unprivileged user.
