Re: Ray Cromwell: Another Netscape Bug (and possible security
On my BSDI2.0 machine running Netscape 1.1N, this causes a segmentation fault and subsequent coredump. GDB reports nothing useable (stripped executable)
I cannot reproduce this bug on the following platforms:
Solaris 2.5 beta/Netscape 1.1N
I've reproduced it fine under sol2.4 1.1N. The page I tested from is http://www.aloha.net/~newsham/test.html. Simply click on the long test url and core dump. (You can view source before clicking to see what you are clicking on if you dont trust me :)

Ive tried this url, it does indeed core dump. Just had a quick look at the core. From first impressions, it's a global overwrite. Therefore we're not overwriting a flushed stack frame, so a syslog(3) style exploit is impossible. Global overwrites can be exploited, but due to the scenario we're looking at, I'd consider exploit chances to be very low indeed.
