high Nessus Plugin ID 93945

Language:

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-201610-03 (Quagga: Arbitrary code execution)

 A memcpy function in the VPNv4 NLRI parser of bgp_mplsvpn.c does not properly check the upper-bound length of received Labeled-VPN SAFI routes data, which may allow for arbitrary code execution on the stack.
 Impact :

 A remote attacker could send a specially crafted packet, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
 Workaround :

 There is no known workaround at this time.

Solution

All Quagga users should upgrade to the latest version:
 # emerge --sync # emerge --ask --oneshot --verbose '>=net-misc/quagga-1.0.20160315'
