When the apr_exp_time*() or apr_os_exp_time*() functions were invoked with an invalid month field value, out of bounds memory may have been be accessed when converting this value to an apr_time_exp_t value. This could have potentially revealed the contents of a different static heap value or resulted in program termination.

For Debian 7 Wheezy, this issue has been fixed in apr version 1.4.6-3+deb7u2.

We recommend that you upgrade your apr packages.");
