<title>Python: Heap overflow in the included PCRE library</title>
The "re" Python module is vulnerable to a heap overflow, possibly leading
to the execution of arbitrary code.

Python is an interpreted, interactive, object-oriented,
cross-platform programming language. The "re" Python module provides
regular expression functions.
The "re" Python module makes use of a private copy of libpcre
which is subject to an integer overflow leading to a heap overflow (see
GLSA 200508-17).
<impact type="normal">
An attacker could target a Python-based web application (or SUID
application) that would use untrusted data as regular expressions,
potentially resulting in the execution of arbitrary code (or privilege
Python users that don't run any Python web application or SUID
application (or that run one that wouldn't use untrusted inputs as
regular expressions) are not affected by this issue.
All Python users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-lang/python-2.3.5-r2&quot;</code>
