Vigil@nce - Linux kernel: information disclosure via x25_negotiate_facilities
May 2016 by Vigil@nce
This bulletin was written by Vigil@nce : https://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
A local attacker can read a memory fragment of
x25_negotiate_facilities() on the Linux kernel, in order to obtain
sensitive information.
Impacted products: Linux.
Severity: 1/4.
Creation date: 11/05/2016.
DESCRIPTION OF THE VULNERABILITY
The Linux kernel implements the X25 protocol.
However, the x25_negotiate_facilities() function of the
net/x25/x25_facilities.c file does not initialize a memory area
before returning it to the user.
A local attacker can therefore read a memory fragment of
x25_negotiate_facilities() on the Linux kernel, in order to obtain
sensitive information.
