CVE-2009-3245

OpenSSL before 0.9.8m does not check for a NULL return value from bnwexpand function calls in 1 crypto/bn/bndiv.c, 2 crypto/bn/bngf2m.c, 3 crypto/ec/ec2smpl.c, and 4 engines/eubsec.c, which has unspecified impact and context-dependent attack vectors...

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...

TLS Client Initiated Renegotiation (CVE-2009-3555)

Transport Layer Security TLS and Secure Sockets Layer SSL are cryptographic protocols that provide security for communications over networks. A spoofing vulnerability exists in multiple implementations of these protocols. The vulnerability is due to the flaw in the renegotiation aspect of the TLS...

Crypto flaws becoming a killer for Web applications

One of the few things that most people in the security community seem to agree on is that there is a dire need for better security around Web applications. That need begins with the lack of security training for most Web developers and extends through the inconsistent use of Web-application...
