TITLE

zsh  Vulnerability in

DESCRIPTION

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. zsh Exists in unspecified vulnerabilities.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. ========================================================================== Ubuntu Security Notice USN-5325-1 March 14, 2022 zsh vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 21.10 - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS - Ubuntu 16.04 ESM Summary: Several security issues were fixed in Zsh. Software Description: - zsh: shell with lots of features Details: Sam Foxman discovered that Zsh incorrectly handled certain inputs. An attacker could possibly use this issue to regain dropped privileges. (CVE-2019-20044) It was discovered that Zsh incorrectly handled certain inputs. An attacker could possibly use this issue to execute arbitrary code. (CVE-2021-45444) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 21.10: zsh 5.8-6ubuntu0.1 zsh-static 5.8-6ubuntu0.1 Ubuntu 20.04 LTS: zsh 5.8-3ubuntu1.1 zsh-static 5.8-3ubuntu1.1 Ubuntu 18.04 LTS: zsh 5.4.2-3ubuntu3.2 zsh-static 5.4.2-3ubuntu3.2 Ubuntu 16.04 ESM: zsh 5.1.1-1ubuntu2.3+esm1 zsh-static 5.1.1-1ubuntu2.3+esm1 In general, a standard system update will make all the necessary changes.
