Summary

CVE-2018-1083
Buffer overflow in the shell autocomplete functionality. A local
unprivileged user can create a specially crafted directory path which
leads to code execution in the context of the user who tries to use
autocomplete to traverse the before mentioned path. If the user
affected is privileged, this leads to privilege escalation.

For Debian 7 "Wheezy", these problems have been fixed in version
4.3.17-1+deb7u2.

We recommend that you upgrade your zsh packages.
