"This update for zsh to version 5.5 fixes the following issues :

Security issues fixed :

  - CVE-2018-1100: Fixes a buffer overflow in
    utils.c:checkmailpath() that can lead to local arbitrary
    code execution (bsc#1089030)

  - CVE-2018-1071: Fixed a stack-based buffer overflow in
    exec.c:hashcmd() (bsc#1084656)

  - CVE-2018-1083: Fixed a stack-based buffer overflow in
    gen_matches_files() at compctl.c (bsc#1087026)

Non-security issues fixed :

  - The effect of the NO_INTERACTIVE_COMMENTS option extends
    into $(...) and `...` command substitutions when used on
    the command line.

  - The 'exec' and 'command' precommand modifiers, and
    options to them, are now parsed after parameter
    expansion.

  - Functions executed by ZLE widgets no longer have their
    standard input closed, but redirected from /dev/null
    instead.

  - There is an option WARN_NESTED_VAR, a companion to the
    existing WARN_CREATE_GLOBAL that causes a warning if a
    function updates a variable from an enclosing scope
    without using typeset -g.

  - zmodload now has an option -s to be silent on a failure
    to find a module but still print other errors.

This update was imported from the SUSE:SLE-15:Update update project.");
