The git-changelog utility in git-extras 1.7.0 allows local users to overwrite arbitrary files via a symlink attack on (1) /tmp/changelog or (2) /tmp/.git-effort.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
