+  <title>Multiple vulnerabilities in LHa</title>
+  <synopsis>
+    Two stack-based buffer overflows and two directory traversal problems have
+    been found in LHa. These vulnerabilities can be used to execute arbitrary
+    code or as a denial of service attack.

+  <description>
+    <p>
+    Ulf Harnhammar found two stack overflows and two directory traversal
+    vulnerabilities in LHa version 1.14 and 1.17. A stack overflow occurs when
+    testing or extracting archives containing long file or directory names.
+    Furthermore, LHa doesn't contain sufficient protection against relative or
+    absolute archive paths.
+    </p>
+  </description>
+  <impact type="high">
+    <p>
+    The stack overflows can be exploited to execute arbitrary code with the
+    rights of the user testing or extracting the archive. The directory
+    traversal vulnerabilities can be used to overwrite files in the filesystem
+    with the rights of the user extracting the archive, potentially leading to
+    denial of service or privilege escalation. Since LHa is often interfaced to
+    other software like an email virus scanner, this attack can be used
+    remotely.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time. All users are advised to upgrade
+    to the latest available version of LHa.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All users of LHa should upgrade to the latest stable version:
