Antoine Delignat-Lavaud from Inria discovered an issue in the way NSS (the Mozilla Network Security Service library) was parsing ASN.1 data used in signatures, making it vulnerable to a signature forgery attack. An attacker could craft ASN.1 data to forge RSA certificates with a valid certification chain to a trusted CA. For the stable distribution (wheezy), this problem has been fixed in version 2:3.14.5-1+deb7u2. For the testing distribution (jessie), this problem has been fixed in version 2:3.17.1. For the unstable distribution (sid), this problem has been fixed in version 2:3.17.1. We recommend that you upgrade your nss packages.
