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

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
