Vigil@nce - ruby-lz4: memory corruption

July 2014 by Vigil@nce

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

SYNTHESIS OF THE VULNERABILITY

An attacker can generate a memory corruption of ruby-lz4, in order
to trigger a denial of service, and possibly to execute code.

Impacted products: Unix (platform)

Severity: 2/4

Creation date: 10/07/2014

DESCRIPTION OF THE VULNERABILITY

The ruby-lz4 product uses LZ4 Core, so it is also impacted by
VIGILANCE-VUL-14947 (https://vigilance.fr/tree/1/14947?w=66901)
and VIGILANCE-VUL-14982 (https://vigilance.fr/tree/1/14982?w=66901).

An attacker can therefore generate a memory corruption of
ruby-lz4, in order to trigger a denial of service, and possibly to
execute code.
