USN-3480-2 fixed regressions in Apport. The update introduced a new regression in the container support. This update addresses the problem.
We apologize for the inconvenience.
Sander Bos discovered that Apport incorrectly handled core dumps for setuid binaries. A local attacker could use this issue to perform a denial of service via resource exhaustion or possibly gain root privileges. (CVE-2017-14177)
Sander Bos discovered that Apport incorrectly handled core dumps for processes in a different PID namespace. A local attacker could use this issue to perform a denial of service via resource exhaustion or possibly gain root privileges.
(CVE-2017-14180).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
