Description:
Paul Jakma has reported a vulnerability in Quagga, which can be exploited by malicious users to cause a DoS (Denial of Service).
The vulnerability is caused due to bgpd not checking the length information of the "MP_UNREACH_NLRI" and "MP_REACH_NLRI" attributes. This can be exploited to cause an assertion error or out of bounds read by sending a specially crafted UPDATE message.
Successful exploitation requires that the attacker is configured as peer of the victim system.
The vulnerability is reported in all existing Quagga versions.
