Severity:	high
Title:	PHP: Integer overflow
Date:	10/30/2006
Bugs:	#150261
ID:	200610-14

Synopsis

PHP is vulnerable to an integer overflow potentially allowing the remote execution of arbitrary code.

Background

PHP is a widely-used general-purpose scripting language that is especially suited for Web development and can be embedded into HTML.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
dev-lang/php	< 5.1.6-r6	>= 4.4.4-r6	All supported architectures

Description

A flaw in the PHP memory handling routines allows an unserialize() call to be executed on non-allocated memory due to a previous integer overflow.

Impact

An attacker could execute arbitrary code with the rights of the web server user or the user running a vulnerable PHP script.

Workaround

There is no known workaround at this time.

Resolution

All PHP 5.x users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-lang/php-5.1.6-r6"

All PHP 4.x users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-lang/php-4.4.4-r6"
