    Debian Bug     : 1009926

    A couple of vulnerabilities were reported against ruby-git, a Ruby
    interface to the Git revision control system, that could lead to a
    command injection and execution of an arbitrary ruby code by having
    a user to load a repository containing a specially crafted filename
    to the product.

    For Debian 11 bullseye, these problems have been fixed in version
    1.7.0-1+deb11u1.

    We recommend that you upgrade your ruby-git packages.

    For the detailed security status of ruby-git please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/ruby-git
