"Florian Weimer discovered that RPM incorrectly handled temporary
files. A local attacker could use this issue to execute arbitrary
code. (CVE-2013-6435)

Florian Weimer discovered that RPM incorrectly handled certain CPIO
headers. If a user or automated system were tricked into installing a
malicious package file, a remote attacker could use this issue to
cause RPM to crash, resulting in a denial of service, or possibly
execute arbitrary code. (CVE-2014-8118).

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.");
