A vulnerability has been identified in OpenSSH, which could be exploited by local attackers to gain knowledge of sensitive information. This issue is caused by an error when binding to a port that has previously been bound with "SO_REUSEADDR" set while the "X11UseLocalhost" option is disabled, which could allow malicious users to hijack sessions via X11 man-in-the-middle attacks on certain operating systems (e.g. HP/UX) that do not check the effective user-id or the overlaping of bind addresses.
