An update for zsh is now available for openEuler-22.03-LTS Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2022-2094 Final 1.0 1.0 2022-11-11 Initial 2022-11-11 2022-11-11 openEuler SA Tool V1.0 2022-11-11 zsh security update An update for zsh is now available for openEuler-22.03-LTS. The zsh is a shell designed for interactive use, and it is also a powerful scripting language. Many of the useful features of bash, ksh, and tcsh were incorporated into zsh. It can match files by file extension without running an external program, share command history with any shell, and more. Security Fix(es): In zsh before 5.8.1, an attacker can achieve code execution if they control a command output inside the prompt, as demonstrated by a %F argument. This occurs because of recursive PROMPT_SUBST expansion.(CVE-2021-45444) An update for zsh is now available for openEuler-22.03-LTS. openEuler Security has rated this update as having a security impact of high.
