Description

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).

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.
