The remote SUSE host is missing one or more security updates.

Description

This update for git fixes the following issues :

On case-insensitive filesystems, 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. (bsc#1183026, CVE-2021-21300)

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
