• Ubuntu 12.04

Details

It was discovered that the distcheck rule in dist-check.mk in GNU
coreutils allows local users to gain privileges via a symlink attack
on a directory tree under /tmp. This issue only affected Ubuntu 10.04 LTS.
(CVE-2009-4135)

Bertrand Jacquin and Fiedler Roman discovered date and touch incorrectly
handled user-supplied input. An attacker could possibly use this to cause
a denial of service or potentially execute code. (CVE-2014-9471)
