Description Janusz 2008-02-10 21:00:27 UTC

"There is a security hole in all versions of linux-2.6 distributed by
Debian, including Etch's kernel."

This is taken from above Debian bugzilla. I confirm it on:

- vanilla 2.6.24.1
- gentoo-sources 2.6.24

both on x86_64. I failed to confirm on vanilla 2.6.23.8 on i586.


Reproducible: Always

Steps to Reproduce:
1.use
2.the exploit
3. included in Debian report! If it disappears for some reasons I can send it to you.

Actual Results:  
System took over by local user.

Expected Results:  
Total disaster. 

I'm waiting for a patch, any local user accounts should be disabled.
