Name of the Vulnerable Software and Affected Versions
Quagga versions prior to 1.2.3
Description
The issue is related to a bug in the parsing of "Capabilities" in BGP OPEN messages. Specifically, the
bgp packet.c:bgp capability msg parse function can enter an infinite loop on invalid capabilities if a Multi-Protocol capability does not have a recognized AFI/SAFI, causing a denial of service.Recommendations
For versions prior to 1.2.3, update to version 1.2.3 or later to resolve the issue. As a temporary workaround, consider restricting the use of the
bgp capability msg parse function until a patch is available.Correção
DoS
Infinite Loop
