+  <synopsis>
+    Multiple vulnerabilities have been discovered in ClamAV allowing remote
+    execution of arbitrary code and Denial of Service attacks.

+    especially for e-mail scanning on mail gateways.

+    iDefense reported an integer overflow vulnerability in the cli_scanpe()
+    function when parsing Portable Executable (PE) files packed in the MEW
+    format, that could be exploited to cause a heap-based buffer overflow
+    (CVE-2007-6335). Toeroek Edwin reported an off-by-one error when
+    decompressing MS-ZIP compressed CAB files (CVE-2007-6336). An
+    unspecified vulnerability related to the bzip2 decompression algorithm
+    has also been discovered (CVE-2007-6337).

+  <impact type="high">
+    <p>
+    A remote attacker could entice a user or automated system to scan a
+    specially crafted file, possibly leading to the execution of arbitrary
+    code with the privileges of the user running ClamAV (either a system
+    user or the "clamav" user if clamd is compromised).
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All ClamAV users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose &quot;&gt;=app-antivirus/clamav-0.91.2-r1&quot;</code>
