+  <title>Davfs2, lvm-user: Insecure tempfile handling</title>
+  <synopsis>
+    Davfs2 and the lvmcreate_initrd script (included in the lvm-user package)
+    are both vulnerable to symlink attacks, potentially allowing a local user
+    to overwrite arbitrary files with the rights of the user running them.

+    <p>
+    Davfs2 is a file system driver that allows you to mount a WebDAV
+    server as a local disk drive. lvm-user is a package providing userland
+    utilities for LVM (Logical Volume Management) 1.x features.

+    <p>
+    Florian Schilhabel from the Gentoo Linux Security Audit Team found
+    that Davfs2 insecurely created .pid files in /tmp. Furthermore, Trustix
+    Secure Linux found that the lvmcreate_initrd script, included in the
+    lvm-user Gentoo package, also creates temporary files in
+    world-writeable directories with predictable names.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A local attacker could create symbolic links in the temporary
+    files directory, pointing to a valid file somewhere on the filesystem.
+    When Davfs2 or lvmcreate_initrd is called, this would result in the
+    file being overwritten with the rights of the user running the
+    software, which could be the root user.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All Davfs2 users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=net-fs/davfs2-0.2.2-r1"</code>
+    <p>
+    All lvm-user users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=sys-fs/lvm-user-1.0.7-r2"</code>
