'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.
