A Solaris 8 patch has been released for the 'xlock' heap overflow vulnerability (108652-40): http://sunsolve.sun.com/securitypatch Sun hasn't released the patches for Solaris 2.6 or 7 yet. I didn't get notice of the Solaris 8 patch through the usual channels (Sun security alert or CERT), thought I'd pass this along.
