Reno,"New point version {{{ Git v2.19.1 Release Notes ========================= This release merges up the fixes that appear in v2.14.5 and in v2.17.2 to address the recently reported CVE-2018-17456; see the release notes for those versions for details. }}} {{{ Git 2.14.5, 2.15.3, 2.16.5, 2.17.2, 2.18.1, and 2.19.1 These releases fix a security flaw (CVE-2018-17456), which allowed an attacker to execute arbitrary code by crafting a malicious .gitmodules file in a project cloned with --recurse-submodules. When running ""git clone --recurse-submodules"", Git parses the supplied .gitmodules file for a URL field and blindly passes it as an argument to a ""git clone"" subprocess. If the URL field is set to a string that begins with a dash, this ""git clone"" subprocess interprets the URL as an option. This can lead to executing an arbitrary script shipped in the superproject as the user who ran ""git clone"". In addition to fixing the security issue for the user running ""clone"", the 2.17.2, 2.18.1 and 2.19.1 releases have an ""fsck"" check which can be used to detect such malicious repository content when fetching or accepting a push. See ""transfer.fsckObjects"" in git-config(1). Credit for finding and fixing this vulnerability goes to joernchen and Jeff King, respectively.
