Debian DSA-1969-1 : krb5 - integer underflow

It was discovered that krb5, a system for authenticating users and services on a network, is prone to integer underflow in the AES and RC4 decryption operations of the crypto library. A remote attacker can cause crashes, heap corruption, or, under extraordinarily unlikely conditions, arbitrary co...

Four Questions for Bruce Schneier on the GSM Cipher Crack

Math is hard and cryptography is even harder. So in light of the news that another of the ciphers used to secure traffic on 3G GSM networks has been cracked, we turned to mathematician and cryptographer Bruce Schneier to explain the attack and its ramifications. So here are Schneier’s answer to a...
