+    <background>
+        <p>RAR and UnRAR provide command line interfaces for compressing and decompressing RAR files.</p>
+    </background>
+    <description>
+        <p>Due to an error in the validation of symbolic links within archives, RAR and UnRAR can potentially write files to a directory which is outside of the intended unpack directory.</p>
+    </description>
+    <impact type="normal">
+        <p>If the user running RAR or UnRAR extracts a malicious archive, the archive could overwrite a file such as the user&#39;s shell initialization scripts, potentially resulting in arbitrary code execution in the context of that user.</p>
+    </impact>
+    <workaround>
+        <p>There is no known workaround at this time.</p>
+    </workaround>
+    <resolution>
+        <p>All RAR users should upgrade to the latest version:</p>
+        
+        <code>
+          # emerge --sync
+          # emerge --ask --oneshot --verbose ">=app-arch/rar-6.12"
+        </code>
