CVE Request: BusyBox tar directory traversal
From: Tyler Hicks <tyhicks () canonical com>

Hello - The BusyBox implementation of tar will extract a symlink that points outside of the current working directory and then follow that symlink when extracting other files. This allows for a directory traversal attack when extracting untrusted tarballs. This behavior was documented in the BusyBox source with the following 2011 commit: http://git.busybox.net/busybox/commit/?id=a116552869db5e7793ae10968eb3c962c69b3d8c I've created an upstream bug report: https://bugs.busybox.net/8411 Can we get a CVE assigned to track this? Thanks! Tyler
