[OE-core] [PATCH] git: CVE-2017-14867

Mon Oct 23 17:39:16 UTC 2017
Git before 2.10.5, 2.11.x before 2.11.4, 2.12.x before 2.12.5, 2.13.x before
2.13.6, and 2.14.x before 2.14.2 uses unsafe Perl scripts to support
subcommands such as cvsserver, which allows attackers to execute arbitrary
OS commands via shell metacharacters in a module name. The vulnerable code
is reachable via git-shell even without CVS support.

+Subject: [PATCH] cvsimport: shell-quote variable used in backticks
+
+We run `git rev-parse` though the shell, and quote its
+argument only with single-quotes. This prevents most
+metacharacters from being a problem, but misses the obvious
+case when $name itself has single-quotes in it. We can fix
+this by applying the usual shell-quoting formula.

+Subject: [PATCH] shell: drop git-cvsserver support by default
+
+The git-cvsserver script is old and largely unmaintained
+these days. But git-shell allows untrusted users to run it
+out of the box, significantly increasing its attack surface.
+
+Let's drop it from git-shell's list of internal handlers so
+that it cannot be run by default. This is not backwards
+compatible. But given the age and development activity on
+CVS-related parts of Git, this is likely to impact very few
+users, while helping many more (i.e., anybody who runs
+git-shell and had no intention of supporting CVS).
+
+There's no configuration mechanism in git-shell for us to
+add a boolean and flip it to "off". But there is a mechanism
+for adding custom commands, and adding CVS support here is
+fairly trivial. Let's document it to give guidance to
+anybody who really is still running cvsserver.
