A vulnerability within Python's copy of PCRE might lead to the execution of
Python is an interpreted, interactive, object-oriented programming
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:
