Package        : zsh
Version        : 4.3.17-1+deb7u2
CVE ID         : CVE-2018-1071 CVE-2018-1083
Debian Bug     : 894044 894043

Two security vulnerabilities were discovered in the Z shell.

CVE-2018-1071
  Stack-based buffer overflow in the exec.c:hashcmd() function.
  A local attacker could exploit this to cause a denial of service.

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.
