Synopsis
========
libpcre is vulnerable to a heap integer overflow, possibly leading to
the execution of arbitrary code.
Background
==========
libpcre is a library providing functions for Perl-compatible regular
expressions.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected

Description
===========

arbitrary code by sending specially crafted regular expressions to
applications making use of the libpcre library.
Workaround
