A flaw was found in the way the Mozilla Network Security Service library (nss) read uninitialized data when there was a decryption failure. A remote attacker could use this flaw to cause a denial of service (application crash) for applications linked with the nss library.
The oldstable distribution (squeeze) is not affected by this problem.
