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.
