Description Josh Bressers 2006-02-16 14:11:47 UTC 
Jim Meyering discovered and silently fixed a buffer overflow bug in GNU
tar.  It looks exploitable.  There is a public mail message about it here:
http://lists.gnu.org/archive/html/bug-tar/2005-06/msg00029.html

My limited testing has shown this issue to only affect tar versions 1.14
and above.

Upstream has asked we not announce this issue until they release an update.
