Vigil@nce - FreeBSD: information disclosure via Linux TIOCGSERIAL
June 2016 by Vigil@nce
SYNTHESIS OF THE VULNERABILITY
A local attacker can read a memory fragment via Linux TIOCGSERIAL
on FreeBSD, in order to obtain sensitive information.
Impacted products: FreeBSD.
Severity: 1/4.
Creation date: 01/06/2016.
DESCRIPTION OF THE VULNERABILITY
The FreeBSD product offers a Linux compatibility layer.
However, the linux_ioctl.c/linux_misc.c file does not initialize a
memory area before returning it to the user.
A local attacker can therefore read a memory fragment via Linux
TIOCGSERIAL on FreeBSD, in order to obtain sensitive information.
