Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

The BGP implementation in bgpd in Quagga before 0.99.20.1 does not properly use message buffers for OPEN messages, which allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a message associated with a malformed Four-octet AS Number Capability (aka AS4 capability).


Remediation

Install update from vendor's website.
