Description: 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.
