FKIE_CVE-2004-2069
Vulnerability from fkie_nvd - Published: 2004-12-31 05:00 - Updated: 2026-06-16 22:08
Severity
Summary
sshd.c in OpenSSH 3.6.1p2 and 3.7.1p2 and possibly other versions, when using privilege separation, does not properly signal the non-privileged process when a session has been terminated after exceeding the LoginGraceTime setting, which leaves the connection open and allows remote attackers to cause a denial of service (connection consumption).
