This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote Gentoo host is missing one or more security-related
patches.

Description :

The remote host is affected by the vulnerability described in GLSA-201709-10
(Git: Command injection)

Specially crafted ‘ssh://...’ URLs may allow the owner of the
repository to execute arbitrary commands on client’s machine if those
commands are already installed on the client’s system. This is
especially dangerous when the third-party repository has one or more
submodules with specially crafted ‘ssh://...’ URLs. Each time the
repository is recursively cloned or submodules are updated the payload
will be triggered.

Impact :

A remote attacker, by enticing a user to clone a specially crafted
repository, could possibly execute arbitrary code with the privileges of
the process.

Workaround :

There is no known workaround at this time.
