| <description> |
| <p> |
| Chris Evans reported multiple integer overflows in the expandtabs |
| method, as implemented by (1) the string_expandtabs function in |
| Objects/stringobject.c and (2) the unicode_expandtabs function in |
| Objects/unicodeobject.c. |
| </p> |
| </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. The security impact is currently unknown but may include the |
| execution of arbitrary code or a Denial of Service. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All Python 2.5 users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=dev-lang/python-2.5.4-r2"</code> |
| <p> |
| All Python 2.4 users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=dev-lang/python-2.4.6"</code> |
