git: arbitrary command execution vulnerability on case-insensitive file systems

Published Feb 12, 2020

Description

Git before 1.8.5.6, 1.9.x before 1.9.5, 2.0.x before 2.0.5, 2.1.x before 2.1.4, and 2.2.x before 2.2.1 on Windows and OS X; Mercurial before 3.2.3 on Windows and OS X; Apple Xcode before 6.2 beta 3; mine all versions before 08-12-2014; libgit2 all versions up to 0.21.2; Egit all versions before 08-12-2014; and JGit all versions before 08-12-2014 allow remote Git servers to execute arbitrary commands via a tree containing a crafted .git/config file with (1) an ignorable Unicode codepoint, (2) a git~1/config representation, or (3) mixed case that is improperly handled on a case-insensitive filesystem.

Remediation

Red Hat statement

This flaw is only exploitable when the local git repository is stored on a case-insensitive filesystem. By default, Red Hat Enterprise Linux uses case-sensitive filesystems (such as ext2/3/4, XFS, etc.) and as such is not vulnerable to this flaw.
