| Python is an interpreted, interactive, object-oriented programming |
| language. |

| Multiple vulnerabilities were discovered in Python: |
| </p> |
| <ul> |
| <li> |
| David Remahl of Apple Product Security reported several integer |
| overflows in core modules such as stringobject, unicodeobject, |
| bufferobject, longobject, tupleobject, stropmodule, gcmodule, |
| mmapmodule (CVE-2008-2315). |
| </li> |
| <li> |
| David Remahl of Apple Product Security also reported an integer |
| overflow in the hashlib module, leading to unreliable cryptographic |
| digest results (CVE-2008-2316). |
| </li> |
| <li> |
| Justin Ferguson reported multiple buffer overflows in unicode string |
| processing that only affect 32bit systems (CVE-2008-3142). |
| </li> |
| <li> |
| The Google Security Team reported multiple integer overflows |
| (CVE-2008-3143). |
| </li> |
| <li> |
| Justin Ferguson reported multiple integer underflows and overflows in |
| the PyOS_vsnprintf() function, and an off-by-one error when passing |
| zero-length strings, leading to memory corruption (CVE-2008-3144). |
| </li> |
| </ul> |
| </description> |
| <impact type="normal"> |
| <p> |
| A remote attacker could exploit these vulnerabilities in Python |
| applications or daemons that pass user-controlled input to vulnerable |
| functions. Exploitation might lead to the execution of arbitrary code |
| or a Denial of Service. Vulnerabilities within the hashlib might lead |
| to weakened cryptographic protection of data integrity or authenticity. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Python 2.4 users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=dev-lang/python-2.4.4-r14"</code> |
| <p> |
| All Python 2.5 users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=dev-lang/python-2.5.2-r6"</code> |
| <p> |
| Please note that Python 2.3 is masked since June 24, and we will not be |
| releasing updates to it. It will be removed from the tree in the near |
| future. |
