+  <title>glibc: Insecure tempfile handling in catchsegv script</title>
+  <synopsis>
+    The catchsegv script in the glibc package is vulnerable to symlink attacks,
+    potentially allowing a local user to overwrite arbitrary files with the
+    rights of the user running the script.
+  </synopsis>

+  <background>
+    <p>
+    glibc is a package that contains the GNU C library.

+  <description>
+    <p>
+    The catchsegv script 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
+    catchsegv script is called, this would result in the file being overwritten
+    with the rights of the user running the utility, which could be the root
+    user.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All glibc users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge sync
+
+    # emerge -pv sys-libs/glibc
+    # emerge sys-libs/glibc</code>
