Description Marcus Meissner 2005-11-08 16:44:36 UTC
CVE-2005-3276

The sys_get_thread_area function in process.c in Linux 2.6 before 2.6.12.4 and 2.6.13 does not clear a data structure before copying it to userspace, which might allow a user process to obtain sensitive information.

I think these info leak issues are really lame. This is your local kernel
stack you're leaking data from - so your chances are really really slim
to find anything useful there.

Marcus, please let me know if you really think this is a must-have.
I think it's a WONTFIX, but if you want it fixed we can do it of course.
It's not a very complex patch :)
Comment 4 Marcus Meissner 2005-11-11 14:45:56 UTC
yes. i agree. near impossible to exploit too.
