CVE-2017-14177
What it is
Apport through 2.20.7 does not properly handle core dumps from setuid binaries allowing local users to create certain files as root which an attacker could leverage to perform a denial of service via resource exhaustion or possibly gain root privileges. NOTE: this vulnerability exists because of an incomplete fix for CVE-2015-1324.
