DESCRIPTION:
Some vulnerabilities have been reported in Cisco IOS XR, which can be
exploited by malicious people to cause a DoS (Denial of Service).
1) An unspecified error exists when processing IPv4 packets
originating from the Cisco Line Card or Cisco CRS MSC and can be
exploited to crash the NetIO process.
Successful exploitation of this vulnerability requires that an IPv4
address is configured on one of the interfaces of a Cisco Line Card
or Cisco CRS MSC.
2) An error in the SSH server when handling an SSHv1 connection does
not delete sshd_lock files in the /tmp directory. This can be
exploited to consume all available disk space in the /tmp filesystem
and cause a crash.
3) An unspecified error when processing IPv4 packets can be exploited
to reload the SPA (Shared Port Adapters) Interface Processor.
Successful exploitation of this vulnerability requires that an IPv4
address is configured on any of the SPA interface processor
interfaces.
Please see the vendor's advisory for the list of affected products
and versions.
