Updated python3 packages fix security vulnerabilities: |
| 22 |
|
| 23 |
A denial of service flaw was found in the way SSL module implementation of |
| 24 |
Python 3 performed matching of the certificate's name in the case it contained |
| 25 |
many '*' wildcard characters. A remote attacker, able to obtain valid |
| 26 |
certificate with its name containing a lot of '*' wildcard characters could use |
| 27 |
this flaw to cause denial of service (excessive CPU consumption) by issuing |
| 28 |
request to validate such a certificate for / to an application using the |
| 29 |
Python's ssl.match_hostname() functionality (CVE-2013-2099). |
| 30 |
|
| 31 |
Ryan Sleevi of the Google Chrome Security Team has discovered that Python's SSL |
| 32 |
module doesn't handle NULL bytes inside subjectAltNames general names. This |
| 33 |
could lead to a breach when an application uses ssl.match_hostname() to match |
| 34 |
the hostname againt the certificate's subjectAltName's dNSName general names. |
| 35 |
(CVE-2013-4238). |
| 36 |
|
| 37 |
Additionally, a linking issue when compiling C extensions for Python 3 has been |
| 38 |
fixed in Mageia 3 (mga#9395). |
| 39 |
|
| 40 |
The CVE-2013-2099 issue also affects bzr, python-requests, python-tornado, |
| 41 |
python-pip, and python-virtualenv, and those have been updated as well. |
