Format string vulnerability in the logging function in the IM Server (aka IMserve or IMserver) in Ipswitch Instant Messaging (IM) 2.0.8.1 and earlier allows remote authenticated users to cause a denial of service (daemon crash) and possibly have unspecified other impact via format string specifiers in an IP address field.
The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
