xosview is an X11 system monitoring application that ships with RedHat 5.1 installed setuid root. A buffer overflow vulnerability was found in Xrm.cc, the offending code listed below:
|
|
|
|
char userrfilename[1024];
|
|
|
|
strcpy(userrfilename, getenv("HOME"));
|
|
|
|
The userfilename can be overflowed and arbritrary code executed to gain root access locally.
|
|
|
|
* xosview 1.5.1 buffer overrun exploit
|
|
|
|
* brought to you by Kossak (ldvg@rnl.ist.utl.pt)
|
|
|
|
*
|
|
|
|
* yep, this is a shameless rip from Aleph's tutorials, but it sure
|
|
|
|
* works... Lets keep those exploits coming!! :)
|
|
|
|
* Thanks to Chris Evans for posting the bug.

|
|
/* NOTE!!! xosview needs an open X display for this to work, so remember
|
|
|
|
* to modify the source (line 62), with your ip.
|
|
|
|
* The offset and buffer size work with me fine, but you might need to
|
|
|
|
* change them.
