Package : python-crypto
Vulnerability : PRNG not correctly reseeded in some situations
Problem type : local
Debian-specific: no
CVE ID : CVE-2013-1445
Debian Bug :

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.
