This update for zsh to version 5.6.2 fixes the following issues :

These security issues were fixed :

  - CVE-2018-0502: The beginning of a #! script file was     mishandled, potentially leading to an execve call to a     program named on the second line (bsc#1107296)

  - CVE-2018-13259: Shebang lines exceeding 64 characters     were truncated, potentially leading to an execve call to     a program name that is a substring of the intended one     (bsc#1107294)

  - CVE-2018-1100: Prevent stack-based buffer overflow in     the utils.c:checkmailpath function that allowed local     attackers to execute arbitrary code in the context of     another user (bsc#1089030).

  - CVE-2018-1071: Prevent stack-based buffer overflow in     the exec.c:hashcmd() function that allowed local     attackers to cause a denial of service (bsc#1084656).

  - CVE-2018-1083: Prevent buffer overflow in the shell     autocomplete functionality that allowed local     unprivileged users to create a specially crafted     directory path which lead to code execution in the     context of the user who tries to use autocomplete to     traverse the mentioned path (bsc#1087026).

  - Disallow evaluation of the initial values of integer     variables imported from the environment

These non-security issues were fixed :

  - Fixed that the signal SIGWINCH was being ignored when     zsh is not in the foreground.

  - Fixed two regressions with pipelines getting     backgrounded and emitting the signal SIGTTOU

  - 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.

  - Fix typo in chflags completion

  - Fixed invalid git commands completion

  - VCS info system: vcs_info git: Avoid a fork.

  - Fix handling of 'printf -' and 'printf --'

  - fix broken completion for filterdiff (boo#1019130)

  - Unicode9 support, this needs support from your terminal     to work correctly.

  - The new word modifier ':P' computes the physical path of     the argument.

  - The output of 'typeset -p' uses 'export' commands or the     '-g' option for parameters that are not local to the     current scope.

  - vi-repeat-change can repeat user-defined widgets if the     widget calls zle -f vichange.

  - The parameter $registers now makes the contents of vi     register buffers available to user-defined widgets.

  - New vi-up-case and vi-down-case builtin widgets bound to     gU/gu (or U/u in visual mode) for doing case conversion.

  - A new select-word-match function provides vim-style text     objects with configurable word boundaries using the     existing match-words-by-style mechanism.

  - Support for the conditional expression [[ -v var ]] to     test if a variable is set for compatibility with other     shells.

  - The print and printf builtins have a new option -v to     assign the output to a variable.

  - New x: syntax in completion match specifications make it     possible to disable match specifications hardcoded in     completion functions.

  - Re-add custom zshrc and zshenv to unbreak compatibility     with old usage (boo#998858).

  - Read /etc/profile as zsh again. 

  - The new module zsh/param/private can be loaded to allow     the shell to define parameters that are private to a     function scope (i.e. are not propagated to nested     functions called within this function).

  - The GLOB_STAR_SHORT option allows the pattern **/* to be     shortened to just ** if no / follows. so **.c searches     recursively for a file whose name has the suffix '.c'.

  - The effect of the WARN_CREATE_GLOBAL option has been     significantly extended, so expect it to cause additional     warning messages about parameters created globally     within function scope.

  - The print builtin has new options -x and -X to expand     tabs.

  - Several new command completions and numerous updates to     others.

  - Options to 'fc' to segregate internal and shared     history.

  - All emulations including 'sh' use multibyte by default;
    several repairs to multibyte handling.

  - ZLE supports 'bracketed paste' mode to avoid     interpreting pasted newlines as accept-line. Pastes can     be highlighted for visibility and to make it more     obvious whether accept-line has occurred.

  - Improved (though still not perfect) POSIX compatibility     for getopts builtin when POSIX_BUILTINS is set.

  - New setopt APPEND_CREATE for POSIX-compatible NO_CLOBBER     behavior.

  - Completion of date values now displays in a calendar     format when the complist module is available.
    Controllable by zstyle.

  - New parameter UNDO_LIMIT_NO for more control over ZLE     undo repeat.

  - Several repairs/improvements to the contributed     narrow-to-region ZLE function.

  - Many changes to child-process and signal handling to     eliminate race conditions and avoid deadlocks on     descriptor and memory management.

  - New builtin sysopen in zsh/system module for detailed     control of file descriptor modes. 

  - Fix a printf regression boo#934175 

  - Global aliases can be created for syntactic tokens such     as command separators (';', '&', '|', '&&', '||'),     redirection operators, etc.

  - There have been various further improvements to builtin     handling with the POSIX_BUILTINS option (off by default)     for compatibility with the POSIX standard.

  - 'whence -v' is now more informative, and 'whence -S'     shows you how a full chain of symbolic links resolves to     a command.

  - The 'p' parameter flag now allows an argument to be     specified as a reference to a variable, e.g.
    $((ps.$sep.)foo) to split $foo on a string given by     $sep.

  - The option FORCE_FLOAT now forces variables, not just     constants, to floating point in arithmetic expressions.

  - The type of an assignment in arithmetic expressions,     e.g. the type seen by the variable res in $(( res = a =     b )), is now more logical and C-like.

  - The default binding of 'u' in vi command mode has     changed to undo multiple changes when invoked     repeatedly. '^R' is now bound to redo changes. To revert     to toggling of the last edit use: bindkey -a u     vi-undo-change

  - Compatibility with Vim has been improved for vi editing     mode. Most notably, Vim style text objects are supported     and the region can be manipulated with vi commands in     the same manner as Vim's visual mode.

  - Elements of the watch variable may now be patterns.

  - The logic for retrying history locking has been     improved.

  - Fix openSUSE versions in osc completion

  - Add back rpm completion file (boo#900424)
