Vulnerability from variot
A vulnerability in Multicast Source Discovery Protocol (MSDP) ingress packet processing for Cisco IOS XR Software could allow an unauthenticated, remote attacker to cause the MSDP session to be unexpectedly reset, causing a short denial of service (DoS) condition. The MSDP session will restart within a few seconds. More Information: CSCvd94828. Known Affected Releases: 4.3.2.MCAST 6.0.2.BASE. Known Fixed Releases: 6.3.1.19i.MCAST 6.2.3.1i.MCAST 6.2.2.17i.MCAST 6.1.4.12i.MCAST. Cisco IOS XR The software contains a buffer error vulnerability. Vendors have confirmed this vulnerability Bug ID CSCvd94828 It is released as.Service operation interruption (DoS) There is a possibility of being put into a state. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. A denial of service vulnerability exists in Cisco IOSXR, which can cause a denial of service (process overload) by sending a constructed SourceDiscoveryProtocol (MSDP) packet. An attacker can exploit this issue to restart the affected process, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCvd94828. The vulnerability is caused by the program not correctly handling errors in MSDP packets
