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

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

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