Severity: High
Title: Quagga: Arbitrary code execution
Date: October 10, 2016
Bugs: #577156
ID: 201610-03
– – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – – –
Synopsis
========
A buffer overflow in Quagga might allow remote attackers to execute
arbitrary code.
Background
==========
Quagga is a free routing daemon replacing Zebra supporting RIP, OSPF
and BGP.
Affected packages
=================
——————————————————————-
Package / Vulnerable / Unaffected
——————————————————————-
1 net-misc/quagga < 1.0.20160315 >= 1.0.20160315
Description
===========
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.
Resolution
==========
All Quagga users should upgrade to the latest version:
# emerge –sync
# emerge –ask –oneshot –verbose “>=net-misc/quagga-1.0.20160315”
