Subject: CVE Request -- dtach: Memory portion (random stack data) disclosure
 to the client by unclean client disconnect

Hello Kurt, Steve, vendors,

   a portion of memory (random stack data) disclosure flaw was found in the way dtach, a simple 
program emulating the detach feature of screen, performed client connection termination under 
certain circumstances. A remote attacker could use this flaw to potentially obtain sensitive 
information by issuing a specially-crafted dtach client connection close request.
