Unknown vulnerability in the systems message queue in HP Tru64 Unix 4.0F PK8 through 5.1B-2/PK4 allows local users to cause a denial of service (process crash) for processes such as nfsstat, pfstat, arp, ogated, rarpd, route, sendmail, srconfig, strsetup, trpt, netstat, and xntpd.
The ps (/usr/ucb/ps) command on HP Tru64 UNIX 5.1 1885 allows local users to obtain sensitive information, including environment variables of arbitrary processes, via the "auxewww" argument, a similar issue to CVE-1999-1587.
