Mandriva Linux Security Advisory MDVSA-2013:229
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : bzr
Date : September 10, 2013
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Updated bzr packages fix security vulnerabilities:

A denial of service flaw was found in the way SSL module implementation
of Python 3 performed matching of the certificate's name in the case
it contained many '*' wildcard characters. A remote
attacker, able to
obtain valid certificate with its name containing a lot of
'*' wildcard
characters could use this flaw to cause denial of service (excessive
CPU consumption) by issuing request to validate such a certificate
for / to an application using the Python's ssl.match_hostname()
functionality (CVE-2013-2099).
