September 2014 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
A local attacker can use a freed memory area in SPL ArrayIterator
of PHP, in order to trigger a denial of service, and possibly to
execute code.
Impacted products: PHP, Slackware
Severity: 2/4
Creation date: 05/09/2014
DESCRIPTION OF THE VULNERABILITY
SPL is a library for PHP that provides implementation of data
structures and associated iterators.
However, if data are changed while the ArrayIterator is run, a
freed memory area is used.
A local attacker can therefore use a freed memory area in SPL
ArrayIterator of PHP, in order to trigger a denial of service, and
possibly to execute code.
