CVE-2013-3710

SUSE Lifecycle Management Server SLMS before 1.3.7 does not generate a new secret key when the service starts, which allows remote attackers to defeat intended cryptographic protection mechanisms by leveraging knowledge of this key from a product installation elsewhere...

Insecure CHIASMUS encryption in GSTOOL

== Insecure CHIASMUS encryption in GSTOOL == GSTOOL versions 3.0 to 4.7 inclusive contain an insecure encryption feature using the non-public CHIASMUS block cipher. Due to the use of an insecure PRNG for key generation, files encrypted using the encryption feature of this tool can be decrypted...

Cryptocat Key Generation Vulnerability Put Chats at Risk

Cryptocat, an open source encrypted Web-based chat application, is taking heat from numerous places after a vulnerability was discovered that put chats at risk for relatively simple decryption, experts say. Worse, says researcher Steve Thomas who found the flaw, is that it likely was present in t...

Some Highway Traffic Systems Open to Man-in-the-Middle Attack

Highway traffic systems deployed across the United States could be open exploit via what a group of researchers has deemed an “insufficient entropy vulnerability” in the systems’ software. According to an advisory .PDF issued late last week by the U.S. Industrial Control System Computer Emergency...

Debian DSA-2502-1 : python-crypto - programming error

It was discovered that that the ElGamal code in PythonCrypto, a collection of cryptographic algorithms and protocols for Python used insecure insufficient prime numbers in key generation, which lead to a weakened signature or public key space, allowing easier brute-force attacks on such keys...

FreeBSD : pycrypto -- vulnerable ElGamal key generation (f45c0049-be72-11e1-a284-0023ae8e59f0)

Dwayne C. Litzenberger of PyCrypto reports : In the ElGamal schemes for both encryption and signatures, g is supposed to be the generator of the entire Z^p group. However, in PyCrypto 2.5 and earlier, g is more simply the generator of a random sub-group of Z^p. The result is that the signature...
