Description Ratul Gupta 2013-12-24 02:03:06 EST
Gitolite was found to be vulnerable to local filesystem information leak, where it could create world writable files in the repositories (particularly the gitolite-admin one) depending on the user umask running gitolite setup.

This is fixed in gitolite3, which is on it's way everywhere it wasn't.

For gitolite, I think the packaging attrs take care of this in all branches.  Can you comfirm?

The patch to correct this is here:


with further discussion here:


which in particular states:

"If you *are* affected, (i.e., you did a fresh install of gitolite 
between fa06a34 and v3.5.3), merely upgrading will NOT fix the problem, 
and you *must* do a one-time chmod fixup as described below. "

the chmod fixup is noted in the workaround section (which is probably useful information to have put here...)

  - EXISTING INSTALLS: if it affects you (see next section for details), 
    you need to do a one-time 'chmod -R go-rwx' (or such) on 
    ~/.gitolite.rc, ~/.gitolite, and ~/repositories/gitolite-admin.git

Finally, the commit that introduced this was fa06a34, which set the umask as early as possible and was committed on September 3 2013 (https://github.com/sitaramc/gitolite/commit/fa06a34) and as a result earlier versions are _NOT_ affected.

Given that gitolite 2.3.1 was released in early 2012, it's not affected.

(As an aside, please don't change the status on SRT bugs; they stay NEW until they are CLOSED.  Thanks.)
