What is CVE-2022-42906?
CVE-2022-42906 is a high-severity command injection vulnerability in Debian Debian Linux, published on 13 Oct 2022. It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.
Official description
powerline-gitstatus (aka Powerline Gitstatus) before 1.3.2 allows arbitrary code execution. git repositories can contain per-repository configuration that changes the behavior of git, including running arbitrary commands. When using powerline-gitstatus, changing to a directory automatically runs git commands in order to display information about the current repository in the prompt. If an attacker can convince a user to change their current directory to one controlled by the attacker, such as in a shared filesystem or extracted archive, powerline-gitstatus will run arbitrary commands under the attacker's control. NOTE: this is similar to CVE-2022-20001.
Weakness: CWE-77
