The latest maintenance release Git v2.17.1 and updates to older maintenance tracks are now available at the usual places.

Fixes since v2.17

  • This release contains the same fixes made in the v2.13.7 version of Git, covering CVE-2018-11233 and 11235, and forward- v2.14.4, v2.15.2 and v2.16.4 releases. See release notes to v2.13.7 for details.
  • In addition to the above fixes, this release adds support on the server side that reject pushes to repositories that attempt to create such problematic .gitmodules file etc. as tracked contents, to help hosting sites protect their customers with older clients by preventing malicious contents from spreading. This is enabled by the same receive.fsckObjects configuration on the server side as other security and sanity related checks (e.g. rejecting tree entry ".GIT" in a wrong case as tracked contents, targetting victims on case insensitive systems) that have already been implemented in the past releases. It is recommended to double check your configuration if you are hosting contents for other people.

Git v2.13.7 Release Notes

  • Submodule "names" come from the untrusted .gitmodules file, but we blindly append them to $GIT_DIR/modules to create our on-disk repo paths. This means you can do bad things by putting "../" into the name. We now enforce some rules for submodule names which will cause Git to ignore these malicious names (CVE-2018-11235).

Credit for finding this vulnerability and the proof of concept from which the test script was adapted goes to Etienne Stalmans.

  • It was possible to trick the code that sanity-checks paths on NTFS into reading random piece of memory (CVE-2018-11233).

Credit for fixing for these bugs goes to Jeff King, Johannes Schindelin and others.
