Some security fixes and some touch ups. tar and unzip are both prone to
undesirable directory traversal (nothing like leaving .. unlinked *shudder*) I
package.masked unzip-5.42 since thier server is busted and I can't test it yet.
http://www.security.nnov.ru/advisories <-- is the advisories. rar is also
suceptible. Remeber you should run archivers under a privleged UID.
