+  <background>
+    <p>Git is a distributed version control system designed.</p>
+  </background>
+  <description>
+    <p>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).
+    </p>
+  </description>
+  <impact type="normal">
+    <p>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.
+    </p>
+  </impact>
+  <workaround>
+    <p>There is no known workaround at this time.</p>
+  </workaround>
+  <resolution>
+    <p>All Git users should upgrade to the latest version:</p>

+    <code>
+      # emerge --sync
+      # emerge --ask --oneshot --verbose "&gt;=dev-vcs/git-2.26.3"
