CVE-2004-2069: OpenBSD OpenSSH

Medium severity, CVSS 5.0. EPSS: 3.4% chance of exploitation in the next 30 days.

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).

Affected products

• OpenBSD OpenSSH: version 3.6.1p2 only; version 3.7.1p2 only
