Python is an interpreted, interactive, object-oriented programming language.
Python 2.3 includes a copy of PCRE which is vulnerable to an integer overflow vulnerability, leading to a buffer overflow.
An attacker could exploit the vulnerability by tricking a vulnerable Python application to compile a regular expressions, which could possibly lead to the execution of arbitrary code, a Denial of Service or the disclosure of sensitive information.
There is no known workaround at this time.
All Python 2.3 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-lang/python-2.3.6-r4"
