[snip] According to the Sun Alert on this vulnerability, http://sunsolve.sun.com/pub-cgi/retrieve.pl?doc=fsalert/55680 Various patchlevels of Solaris 2.6, 7, 8, and 9 sparc and i386 are all vulnerable. On Solaris 2.5.1, $ uname -a SunOS wallace 5.5.1 Generic_103640-40 sun4u sparc SUNW,Ultra-Enterprise When I try the simple, $ LD_PRELOAD=/`perl -e 'print "A"x2000'`/ passwd passwd: Changing password for cclark Enter login(NIS) password: It doesn't crash. That reassures me somewhat, but does anyone know if 2.5.1 is not listed because it is (a) no longer supported and not tested and patched, or (b) not actually vulnerable? Thanks. -- Crist J.
