USN-126-1: GNU TLS library vulnerability

Publication date

Overview

GNU TLS library vulnerability

Releases


Details

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 consistency 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.
