The information in the following Security Bulletin should be acted upon
as soon as possible. Hewlett-Packard Company will not be liable for any
consequences to any customer resulting from customer's failure to fully

PROBLEM: The SharedX program recserv is vulnerable to a denial of
service attack.

I.
A. Background
HP SharedX Receiver Service (recserv) provides a method for a
receiver to allow the sharing of windows without explicitly
performing any xhost commands. The Internet daemon, inetd,
executes recserv when it receives a service request at the port
listed in the services database. Certain messages to the port
can cause recserv to enter a tight processing loop
B. Fixing the problem - Install the applicable patch:
HP-UX revision 10.01 HP9000 Series 7/800 PHSS_16646
HP-UX revision 10.10 HP9000 Series 7/800 PHSS_16647
HP-UX revision 10.20 HP9000 Series 7/800 PHSS_16648
HP-UX revision 11.00 HP9000 Series 7/800 PHSS_16649
Note - For HP-UX revisions prior to 10.01, update to 10.X,
or 11.X and install the applicable patch.
