+        <p>GNU Gzip is a popular data compression program.
+
+XZ Utils is free general-purpose data compression software with a high compression ratio.</p>

+    <description>
+        <p>GNU Gzip and XZ Utils&#39; grep helpers do not sufficiently validate certain multi-line file names.</p>
+    </description>
+    <impact type="high">
+        <p>In some cases, writing to arbitrary files such as shell initialization files can be escalation to remote code execution.</p>
+    </impact>
+    <workaround>
+        <p>Ensuring only trusted input is passed to GNU Gzip and XZ Utils&#39; grep helpers minimizes the potential impact.</p>
+    </workaround>
+    <resolution>
+        <p>All GNU Gzip users should upgrade to the latest version:</p>
+        
+        <code>
+          # emerge --sync
+          # emerge --ask --oneshot --verbose ">=app-arch/gzip-1.12"
+        </code>
+        
+        <p>All XZ Utils users should upgrade to the latest version:</p>
