Mandriva Linux Security Advisory : python-pycrypto (MDVSA-2012:117)

Medium Nessus Plugin ID 61968


The remote Mandriva Linux host is missing a security update.


A vulnerability has been discovered and corrected in python-pycrypto :

PyCrypto before 2.6 does not produce appropriate prime numbers when using an ElGamal scheme to generate a key, which reduces the signature space or public key space and makes it easier for attackers to conduct brute-force attacks to obtain the private key (CVE-2012-2417).

The updated packages have been patched to correct this issue.


Update the affected python-pycrypto package.
