Gentoo Linux Security Advisory

Title: Python: Integer overflows (GLSA 200907-16)
Severity: normal
Exploitable: remote
Date: July 19, 2009
Bug(s): #246991
ID: 200907-16

Synopsis


Multiple integer overflows in Python have an unspecified impact.


Background


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


Affected Packages

Package: dev-lang/python
Vulnerable: < 2.5.4-r2
Unaffected: >= 2.5.4-r2
Unaffected: >= 2.4.6 < 2.4.7
Architectures: All supported architectures


Description


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.


Impact


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.


Workaround


There is no known workaround at this time.


Resolution


All Python 2.5 users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-lang/python-2.5.4-r2"

All Python 2.4 users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-lang/python-2.4.6"
