Synopsis
========

A buffer overflow vulnerability in PECL APC might allow for the remote
execution of arbitrary code.

Background
==========

PECL Alternative PHP Cache (PECL APC) is a free, open, and robust
framework for caching and optimizing PHP intermediate code.

Affected packages
=================

    -------------------------------------------------------------------
     Package            /   Vulnerable   /                  Unaffected
    -------------------------------------------------------------------
  1  dev-php5/pecl-apc      < 3.0.16-r1                   >= 3.0.16-r1

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

Daniel Papasian discovered a stack-based buffer overflow in the
apc_search_paths() function in the file apc.c when processing long
filenames.

Impact
======

A remote attacker could exploit this vulnerability to execute arbitrary
code in PHP applications that pass user-controlled input to the
include() function.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All PECL APC users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-php5/pecl-apc-3.0.16-r1"
