Summary

Git could be made to run programs as your login if it recursively

opened a malicious git repository.

Software Description:

- git: fast, scalable, distributed revision control system

Details:

It was discovered that git did not properly validate git submodule

urls or paths. A remote attacker could possibly use this to craft a

git repository that causes arbitrary code execution when recursive

operations are used.
