Updated polarssl, pdns & ragel packages fix CVE-2013-5915

Publication date: 30 Nov 2013
Type: security
Affected Mageia releases : 3
CVE: CVE-2013-5915


Updated polarssl packages fix security vulnerability:

The researchers Cyril Arnaud and Pierre-Alain Fouque investigated the PolarSSL
RSA implementation and discovered a bias in the implementation of the Montgomery
multiplication that we used. For which they then show that it can be used to
mount an attack on the RSA key. Although their test attack is done on a local
system, there seems to be enough indication that this can properly be performed
from a remote system as well (CVE-2013-5915).

Also, the pdns package has been updated to work with the updated polarssl.
