Description Jan Lieskovsky 2012-06-27 09:52:56 UTC 
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.
