+  <title>LHa: Multiple vulnerabilities</title>
+  <synopsis>
+    Several buffer overflows and a shell metacharacter command execution
+    vulnerability have been found in LHa. These vulnerabilities can be used to
+    execute arbitrary code.

+    <p>
+    LHa is a console-based program for packing and unpacking LHarc archives.

+  <description>
+    <p>
+    The command line argument as well as the archive parsing code of LHa lack
+    sufficient bounds checking. Furthermore, a shell meta character command
+    execution vulnerability exists in LHa, since it does no proper filtering on
+    directory names.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    Using a specially crafted command line argument or archive, an attacker can
+    cause a buffer overflow and could possibly run arbitrary code. The shell
+    meta character command execution could lead to the execution of arbitrary
+    commands by an attacker using directories containing shell meta characters
+    in their names.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All LHa users should upgrade to the latest stable version:
