+  <title>MySQL: Insecure temporary file creation in mysqlhotcopy</title>
+  <synopsis>
+    The mysqlhotcopy utility can create temporary files with predictable paths,
+    allowing an attacker to use a symlink to trick MySQL into overwriting
+    important data.

+  <background>
+    <p>
+    MySQL is a popular open-source multi-threaded, multi-user SQL database
+    server.

+  <description>
+    <p>
+    Jeroen van Wolffelaar discovered that the MySQL database hot copy utility
+    (mysqlhotcopy.sh), when using the scp method, uses temporary files with
+    predictable names. A malicious local user with write access to the /tmp
+    directory could create a symbolic link pointing to a file, which may then
+    be overwritten. In cases where mysqlhotcopy is run as root, a malicious
+    user could create a symlink to a critical file such as /etc/passwd and
+    cause it to be overwritten.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A local attacker could use this vulnerability to destroy other users' data
+    or corrupt and destroy system files, possibly leading to a denial of
+    service condition.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All MySQL users should upgrade to the latest version:
+    </p>
+    <code>
+    # emerge sync
+
+    # emerge -pv ">=dev-db/mysql-4.0.20-r1"
+    # emerge ">=dev-db/mysql-4.0.20-r1"</code>
+  </resolution>
