A cryptographic vulnerability was discovered in the pseudo random number generator in python-crypto. In some situations, a race condition could prevent the reseeding of the generator when multiple processes are forked from the same parent. This would lead it to generate identical output on all processes, which might leak sensitive values like cryptographic keys.

For the oldstable distribution (squeeze), this problem has been fixed in version 2.1.0-2+squeeze2. For the stable distribution (wheezy), this problem has been fixed in version 2.6-4+deb7u3. For the testing distribution (jessie), this problem has been fixed in version 2.6.1-2. For the unstable distribution (sid), this problem has been fixed in version 2.6.1-1. We recommend that you upgrade your python-crypto packages.

A collection of cryptographic algorithms and protocols, implemented for use from Python. Among the contents of the package:
