x/vulndb: potential Go vuln in github.com/git-for-windows/git: CVE-2022-41953

[GoVulnBot]

CVE-2022-41953 references github.com/git-for-windows/git, which may be a Go module.

Description:
Git GUI is a convenient graphical tool that comes with Git for Windows. Its target audience is users who are uncomfortable with using Git on the command-line. Git GUI has a function to clone repositories. Immediately after the local clone is available, Git GUI will automatically post-process it, among other things running a spell checker called aspell.exe if it was found. Git GUI is implemented as a Tcl/Tk script. Due to the unfortunate design of Tcl on Windows, the search path when looking for an executable always includes the current directory. Therefore, malicious repositories can ship with an aspell.exe in their top-level directory which is executed by Git GUI without giving the user a chance to inspect it first, i.e. running untrusted code. This issue has been addressed in version 2.39.1. Users are advised to upgrade. Users unable to upgrade should avoid using Git GUI for cloning. If that is not a viable option, at least avoid cloning from untrusted sources.
