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
    -------------------------------------------------------------------
  1  dev-libs/libpcre        < 6.3                              >= 6.3

Description
==========
libpcre fails to check certain quantifier values in regular expressions
for sane values.

Impact
=====
An attacker could possibly exploit this vulnerability to execute
arbitrary code by sending specially crafted regular expressions to
applications making use of the libpcre library.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All libpcre users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-libs/libpcre-6.3"
