Description

It was discovered that RPM incorrectly handled certain package headers. If a user or automated system were tricked into installing a specially crafted RPM package, an attacker could cause RPM to crash, resulting in a denial of service, or possibly execute arbitrary code.

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.
