<!-- Firefox 1.5 buffer overflow
|
|
|
|
Basically firefox logs all kinda of URL data in it's history.dat file,
|
|
this little script will set a really large topic and Firefox will then
|
|
save that topic into it's history.dat.. The next time that firefox is
|
|
opened, it will instantly crash due to a buffer overflow -- this will
|
|
happen everytime until you manually delete the history.dat file -- which
|
|
most users won't figure out.
|
|
|
|
this proof of concept will only prevent someone from reopening
|
|
their browser after being exploited. DoS if you will. however, code
|
|
execution is possible with some modifcations.
|
|
|
|
Tested with Firefox 1.5 on Windows XP SP2.
