A buffer overflow flaw was found in the zsh shell auto-complete 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 auto-complete to traverse the before mentioned path. If the user affected is privileged, this leads to privilege escalation.
