Package : powerline-gitstatus
Version : 1.3.2-0+deb10u1
CVE ID : CVE-2022-42906

Powerline Gitstatus, a status line plugin for the VIM editor, 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.

For Debian 10 buster, this problem has been fixed in version
1.3.2-0+deb10u1.

We recommend that you upgrade your powerline-gitstatus packages.
