+  <title>f2c: Insecure temporary file creation</title>
+  <synopsis>
+    f2c is vulnerable to symlink attacks, potentially allowing a local user to
+    overwrite arbitrary files.

+  <background>
+    <p>
+    f2c is a Fortran to C translator. Portage uses this package in
+    some ebuilds to build Fortran sources.

+  <description>
+    <p>
+    Javier Fernandez-Sanguino Pena from the Debian Security Audit Team
+    discovered that f2c 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 f2c is executed, 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 f2c users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge --sync
+    # emerge --ask --oneshot --verbose "&gt;=dev-lang/f2c-20030320-r1"</code>
