Ubuntu 12.04 LTS / 14.04 LTS / 14.10 : libksba vulnerability (USN-2427-1)

Medium Nessus Plugin ID 79623


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


Hanno Bock discovered that Libksba incorrectly handled certain S/MIME messages or ECC based OpenPGP data. An attacker could use this issue to cause Libksba 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.


Update the affected libksba8 package.
