| Description: | Git is an open-source distributed revision control system. In affected
versions of Git a specially crafted repository that contains symbolic
links as well as files using a clean/smudge filter such as Git LFS,
may cause just-checked out script to be executed while cloning onto a
case-insensitive file system such as NTFS, HFS+ or APFS (i.e. the
default file systems on Windows and macOS). Note that clean/smudge
filters have to be configured for that. Git for Windows configures Git
LFS by default, and is therefore vulnerable. The problem has been
patched in the versions published on Tuesday, March 9th, 2021. As a
workaound, if symbolic link support is disabled in Git (e.g. via `git
config --global core.symlinks false`), the described attack won't
work. Likewise, if no clean/smudge filters such as Git LFS are
configured globally (i.e. _before_ cloning), the attack is foiled. As
always, it is best to avoid cloning repositories from untrusted
sources. The earliest impacted version is 2.14.2. The fix versions
are: 2.30.1, 2.29.3, 2.28.1, 2.27.1, 2.26.3, 2.25.5, 2.24.4, 2.23.4,
2.22.5, 2.21.4, 2.20.5, 2.19.6, 2.18.5, 2.17.62.17.6.
