Updated python3, bzr and some python packages fix security vulnerabilties
Publication date: 22 Aug 2013Modification date: 26 Aug 2013
Type: security
Affected Mageia releases : 2 , 3
CVE: CVE-2013-2099 , CVE-2013-4238
Description
Updated python3 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). Ryan Sleevi of the Google Chrome Security Team has discovered that Python's SSL module doesn't handle NULL bytes inside subjectAltNames general names. This could lead to a breach when an application uses ssl.match_hostname() to match the hostname againt the certificate's subjectAltName's dNSName general names. (CVE-2013-4238). Additionally, a linking issue when compiling C extensions for Python 3 has been fixed in Mageia 3 (mga#9395). The CVE-2013-2099 issue also affects bzr, python-requests, python-tornado, python-pip, and python-virtualenv, and those have been updated as well.
