Advisory:
========================

Updated git packages fix security vulnerability:

On case-insensitive file systems with support for symbolic links, if Git is
configured globally to apply delay-capable clean/smudge filters (such as Git
LFS), Git could be fooled into running remote code during a clone
(CVE-2021-21300).
