+  <title>libarchive (formerly named as bsdtar): Multiple PaX Extension Header Vulnerabilities</title>
+  <synopsis>
+    Multiple vulnerabilities were found in libarchive (formerly named as
+    app-archive/bsdtar), possibly allowing for the execution of arbitrary code
+    or a Denial of Service.

+    <p>
+    libarchive is a library for manipulating different streaming archive
+    formats, including certain tar variants, several cpio formats, and both
+    BSD and GNU ar variants.

+    CPNI, CERT-FI, Tim Kientzle, and Colin Percival reported a buffer
+    overflow (CVE-2007-3641), an infinite loop (CVE-2007-3644), and a NULL
+    pointer dereference (CVE-2007-3645) within the processing of archives
+    having corrupted PaX extension headers.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    An attacker can trick a user or automated system to process an archive
+    with malformed PaX extension headers into execute arbitrary code, crash
+    an application using the library, or cause a high CPU load.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All libarchive or bsdtar users should upgrade to the latest libarchive
+    version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=app-arch/libarchive-2.2.4"</code>
