Vulnerability from variot
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

- 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
