Ubuntu 14.04 LTS : libytnef vulnerabilities (USN-3288-1)

Medium Nessus Plugin ID 100219


The remote Ubuntu host is missing a security-related patch.


It was discovered that libytnef incorrectly handled malformed TNEF streams. If a user were tricked into opening a specially crafted TNEF attachment, an attacker could cause 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.


Update the affected libytnef0 package.
