Specifying an incorrectly formatted file to /usr/bin/tar's -I option causes the program to crash with a segmentation fault.

I 
>How-To-Repeat:
Run the following command:

tar tIvf /kernel

(nevermind that the command is nonsensical; it should not crash tar)
>Fix:
Unknown; suspect buffer overflow in tar.

State-Changed-Why:  
I believe that this has been fixed in -stable after 4.3 was released. 
Can you try updating your system to 4.3-STABLE (which is currently 
4.4-PRERELEASE) and see if this problem persists?
