PECL APC: Buffer Overflow — GLSA 200804-07

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

Affected Packages

dev-php5/pecl-apc on all architectures
Affected versions < 3.0.16-r1
Unaffected versions >= 3.0.16-r1

Background

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

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"
