Vigil@nce: PHP, memory reading via mb_strcut

November 2010 by Vigil@nce

This bulletin was written by Vigil@nce : http://vigilance.fr/

SYNTHESIS OF THE VULNERABILITY

An attacker can use a PHP application using the mb_strcut()
function, in order to read a memory fragment.

 Severity: 1/4
 Creation date: 08/11/2010

DESCRIPTION OF THE VULNERABILITY

The mb_strcut() function, which uses libmbfl, is used to extract a
substring from a string using a Multi-Byte encoding:
mb_strcut(string, start, length);

However, if the start position is inside a Multi-Byte character,
the mb_strcut() function reads after the end of the string.

An attacker can therefore use a PHP application using the
mb_strcut() function, in order to read a memory fragment.
