HP-UX contains a flaw that may allow a remote denial of service. The issue is triggered when sending certain messages to the listening port of the SharedX Receiver Service (recserv) program, which causes the service to enter a infinite processing loop, and will result in loss of availability for the service. No further details have been provided.
Currently, there are no known workarounds or upgrades to correct this issue. However, Hewlett-Packard has released a patch to address this vulnerability.
