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"
