+  <title>Insecure Temporary File Creation In MySQL</title>
+  <synopsis>
+    Two MySQL utilities create temporary files with hardcoded paths, allowing
+    an attacker to use a symlink to trick MySQL into overwriting important
+    data.

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

+  <description>
+    <p>
+    The MySQL bug reporting utility (mysqlbug) creates a temporary file to log
+    bug reports to. A malicious local user with write access to the /tmp
+    directory could create a symbolic link of the name mysqlbug-<i>N</i>
+    pointing to a protected file, such as /etc/passwd, such that when mysqlbug
+    creates the <i>N</i>th log file, it would end up overwriting the target
+    file. A similar vulnerability exists with the mysql_multi utility, which
+    creates a temporary file called mysql_multi.log.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    Since mysql_multi runs as root, a local attacker could use this to destroy
+    any other users' data or corrupt and destroy system files.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    One could modify both scripts to log to a directory that users do not have
+    write permission to, such as /var/log/mysql/.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All users should upgrade to the latest stable version of MySQL.
+    </p>
