Hello MITRE, all,

The git project announced v2.6.1 https://lkml.org/lkml/2015/10/5/683
and included the following text:

       * Some protocols (like git-remote-ext) can execute arbitrary code
         found in the URL. The URLs that submodules use may come
         from arbitrary sources (e.g., .gitmodules files in a remote
         repository), and can hurt those who blindly enable recursive
         fetch. Restrict the allowed protocols to well known and
         safe ones.

The following commits appear to implement the restrictions:

I do not know if this is exhaustive.

The announcement also mentions some int-based overflows but does not
describe any situations that would allow crossing privilege boundaries.

Please assign CVEs as appropriate.

Can CVE be assigned to this vulnerability please?
