Ubuntu 4.10 / 5.04 : gnutls11, gnutls10 vulnerability (USN-126-1)

Medium Nessus Plugin ID 20516


The remote Ubuntu host is missing one or more security-related patches.


A Denial of Service vulnerability was discovered in the GNU TLS library, which provides common cryptographic algorithms and is used by many applications in Ubuntu. Due to a missing sanity check of the padding length field, specially crafted ciphertext blocks caused an out of bounds memory access which could crash the application. It was not possible to exploit this to execute any attacker specified 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 packages.
