A buffer overflow vulnerability in the /usr/lib/fs/ufs/ufsdump setuid program allows local users to obtain root and tty group access. The vulnerability is the result of 'ufsdump' not being able to handle device names of a large length.

/* ufsdump.c
|
|
* Description: Overflows a buffer to give you EGID=tty.
|
|
* At least that's what id reports.
|
|
* The running shell thinks its still the user. Maybe I'm
|
|
* doing something wrong? At any
|
|
* rate, here ya go, have fun.
|

* smm@wpi.edu
|
|
* Thanks to: Jesse Schachter for the box, and
|
|
* Unknown parties for the shellcode. (probably Aleph1).
