Language:

Synopsis

The remote SUSE host is missing one or more security updates.

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.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
