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"
