CentOS 6 : zsh (CESA-2018:1932)

High Nessus Plugin ID 110652

Synopsis

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

Description

An update for zsh is now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

The zsh shell is a command interpreter usable as an interactive login
shell and as a shell script command processor. Zsh resembles the ksh
shell (the Korn shell), but includes many enhancements. Zsh supports
command-line editing, built-in spelling correction, programmable
command completion, shell functions (with autoloading), a history
mechanism, and more.

Security Fix(es) :

* zsh: Stack-based buffer overflow in gen_matches_files() at compctl.c
(CVE-2018-1083)

* zsh: buffer overflow when scanning very long directory paths for
symbolic links (CVE-2014-10072)

* zsh: buffer overrun in symlinks (CVE-2017-18206)

* zsh: buffer overflow in utils.c:checkmailpath() can lead to local
arbitrary code execution (CVE-2018-1100)

For more details about the security issue(s), including the impact, a

The CVE-2018-1083 and CVE-2018-1100 issues were discovered by Richard
