The latest maintenance release Git v2.14.1 is now available at the usual places, together with releases for older maintenance track for the same issue: v2.7.6, v2.8.6, v2.9.5, v2.10.4, v2.11.3, v2.12.4, and v2.13.5.
These contain a security fix for CVE-2017-1000117, and are released in coordination with Subversion and Mercurial that share a similar issue. CVE-2017-9800 and CVE-2017-1000116 are assigned to these systems, respectively, for issues similar to it that are now addressed in their part of this coordinated release. The tarballs are found at: https://www.kernel.org/pub/software/scm/git/ The following public repositories all have a copy of these tags: url = https://kernel.googlesource.com/pub/scm/git/git url = git://repo.or.cz/alt-git.git url = https://github.com/gitster/git A malicious third-party can give a crafted "ssh://..." URL to an unsuspecting victim, and an attempt to visit the URL can result in any program that exists on the victim's machine being executed. Such a URL could be placed in the .gitmodules file of a malicious project, and an unsuspecting victim could be tricked into running "git clone --recurse-submodules" to trigger the vulnerability. Credits to find and fix the issue go to Brian Neel at GitLab, Joern Schneeweisz of Recurity Labs and Jeff King at GitHub. * A "ssh://..." URL can result in a "ssh" command line with a hostname that begins with a dash "-", which would cause the "ssh" command to instead (mis)treat it as an option. This is now prevented by forbidding such a hostname (which should not impact any real-world usage). * Similarly, when GIT_PROXY_COMMAND is configured, the command is run with host and port that are parsed out from "ssh://..." URL; a poorly written GIT_PROXY_COMMAND could be tricked into treating a string that begins with a dash "-" as an option. This is now prevented by forbidding such a hostname and port number (again, which should not impact any real-world usage). * In the same spirit, a repository name that begins with a dash "-" is also forbidden now.
