A buffer overflow vulnerability in PECL APC might allow for the remote

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
