USN126-1 : gnutls11, gnutls10 vulnerability

Vulnerability Assessment Summary
gnutls11, gnutls10 vulnerability

Detailed Explanation for this Vulnerability Assessment

Summary :

These remote packages are missing security patches :
- gnutls-bin
- libgnutls-doc
- libgnutls10
- libgnutls10-dev
- libgnutls11
- libgnutls11-dbg
- libgnutls11-dev

Description :

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.

Solution :

Upgrade to :
- gnutls-bin-1.0.16-13ubuntu0.1 (Ubuntu 5.04)
- libgnutls-doc-1.0.4-3ubuntu1.1 (Ubuntu 4.10)
- libgnutls10-1.0.4-3ubuntu1.1 (Ubuntu 4.10)
- libgnutls10-dev-1.0.4-3ubuntu1.1 (Ubuntu 4.10)
- libgnutls11-1.0.16-13ubuntu0.1 (Ubuntu 5.04)
