Name of the Vulnerable Software and Affected Versions:
SCALANCE XM-400 versions prior to v6.4
XR-500 versions prior to v6.4
Description:
An unauthenticated remote attacker could create a permanent denial-of-service condition by sending specially crafted OSPF packets. Successful exploitation requires OSPF to be enabled on an affected device.
Recommendations:
For SCALANCE XM-400 versions prior to v6.4, update to version v6.4 or later to resolve the issue.
For XR-500 versions prior to v6.4, update to version v6.4 or later to resolve the issue.
As a temporary workaround, consider disabling OSPF on affected devices until a patch is available.
