Cisco Security Advisory - The SSH server implementation in Cisco IOS XR Software contains a vulnerability that an unauthenticated, remote user could exploit to cause a denial of service condition. An attacker could trigger this vulnerability by sending a crafted SSH version 2 packet that may cause a new SSH connection handler process to crash. Repeated exploitation may cause each new SSH connection handler process to crash and lead to a significant amount of memory being consumed, which could introduce instability that may adversely impact other system functionality. During this event, the parent SSH daemon process will continue to function normally.
