openSUSE Security Update: Security update for zsh

Announcement ID: openSUSE-SU-2018:1893-1
Rating: moderate
References: #1084656 #1087026 #1089030
Cross-References: CVE-2018-1071 CVE-2018-1083 CVE-2018-1100

Affected Products:
openSUSE Leap 15.0

An update that fixes three vulnerabilities is now available.


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()
– 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.
