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 &quot;&gt;=dev-php5/pecl-apc-3.0.16-r1&quot;
