Debian DSA-3532-1 : quagga - security update

high Nessus Plugin ID 90207

Synopsis

The remote Debian host is missing a security-related update.

Description

Kostya Kortchinsky discovered a stack-based buffer overflow vulnerability in the VPNv4 NLRI parser in bgpd in quagga, a BGP/OSPF/RIP routing daemon. A remote attacker can exploit this flaw to cause a denial of service (daemon crash), or potentially, execution of arbitrary code, if bgpd is configured with BGP peers enabled for VPNv4.

Solution

Upgrade the quagga packages.

For the oldstable distribution (wheezy), this problem has been fixed in version 0.99.22.4-1+wheezy2.

For the stable distribution (jessie), this problem has been fixed in version 0.99.23.1-1+deb8u1.
