Multiple integer overflows in Python have an unspecified impact.
|Package||dev-lang/python on all architectures|
|Affected versions||< 2.5.4-r2|
|Unaffected versions||>= 2.5.4-r2, revision >= 2.4.6|
Python is an interpreted, interactive, object-oriented programming language.
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.
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.
There is no known workaround at this time.
All Python 2.5 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/python-2.5.4-r2"
All Python 2.4 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-lang/python-2.4.6"
