Date: April 09, 2008

Background

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

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.
