Synopsis
========

A buffer overflow in PECL HTTP might allow remote attackers to execute
arbitrary code.

Background
==========

This HTTP extension aims to provide a convenient and powerful
set of functionality for one of PHPs major applications.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-php/pecl-http < 2.5.6 *>= 2.5.6

Description
===========

A buffer overflow can be triggered in the URL parsing functions of the
PECL HTTP extension. This allows overflowing
a buffer with data originating from an arbitrary HTTP request.

Impact
======

A remote attacker, through a specially crafted URI, could possibly
execute arbitrary code with the privileges of the process.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All PECL HTTP users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-php/pecl-http-2.5.6"

References
==========
