Synopsis
========

A vulnerability has been found in Git that could allow a remote
attacker to execute arbitrary code.

Background
==========

Git is a distributed version control system designed.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-vcs/git < 2.26.3 >= 2.26.3

Description
===========

It was discovered that Git could be fooled into running remote code
during a clone 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).

Impact
======

A remote attacker could entice a user to clone a specially crafted
repository, possibly resulting in the remote execution of arbitrary
code with the privileges of the user running the application.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Git users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-vcs/git-2.26.3"

References
==========
