Description:
Fredrik Widell has reported a vulnerability in Quagga, which can be exploited by malicious, local users to cause a DoS (Denial of Service).
The vulnerability is caused due to an infinite loop error in bgpd within the "community_str2com()" function. This can be exploited to cause the process to consume large amounts of CPU resources by issuing the "sh ip bgp command" command via the telnet management interface.
The vulnerability has been reported in version 0.98.3. Other versions may also be affected.
Solution:
Update to version 0.98.6.
