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 [ CONTENT OF TYPE application/pgp-signature SKIPPED ]
