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.
