Stack-based buffer overflow in Pragma FortressSSH 4.0.7.20 allows remote attackers to execute arbitrary code via long SSHMSGKEXINIT messages, which may cause an overflow when being logged. NOTE: the provenance of this information is unknown; the details are obtained solely from third party information.

Pragma FortressSSH 5.0 Build 4 Revision 293 and earlier handles long input to sshd.exe by creating an error-message window and waiting for the administrator to click in this window before terminating the sshd.exe process, which allows remote attackers to cause a denial of service (connection slot exhaustion) via a flood of SSH connections with long data objects, as demonstrated by (1) a long list of keys and (2) a long username.
