Comment 3 Lewis Smith 2021-03-09 21:06:02 CET

Quick work! It will need the advisory.

Comment 4 David Walser 2021-03-10 00:31:12 CET

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).
