Ubuntu 10.04 LTS / 12.04 LTS / 13.10 / 14.04 LTS : gnutls26 vulnerability (USN-2229-1)

Medium Nessus Plugin ID 74285


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


Joonas Kuorilehto discovered that GnuTLS incorrectly handled Server Hello messages. A malicious remote server or a man in the middle could use this issue to cause GnuTLS 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 libgnutls26 package.
