Description: 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 commandcompletion, 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 CVSS score, and other related information, refer to the CVE page(s) listed in the References section. The CVE-2018-1083 and CVE-2018-1100 issues were discovered by Richard Maciel Costa (Red Hat).
