November 2017 by Vigil@nce
This bulletin was written by Vigil@nce : https://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can force a NULL pointer to be dereferenced via
assoc_array_apply_edit() of the Linux kernel, in order to trigger
a denial of service.
Impacted products: Fedora, Linux.
Severity: 1/4.
Creation date: 02/11/2017.
DESCRIPTION OF THE VULNERABILITY
The Noyau Linux product offers a web service.
However, it does not check if a pointer is NULL, before using it.
An attacker can therefore force a NULL pointer to be dereferenced
via assoc_array_apply_edit() of the Linux kernel, in order to
trigger a denial of service.
