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 10 buster, these problems have been fixed in version 1.2.8-1+deb10u1.
We recommend that you upgrade your ruby-git packages.
