CVE-2024-6387: regreSSHion RCE in OpenSSH Vulnerability

A signal handler race condition was found in OpenSSH's server sshd, where a client does not authenticate within LoginGraceTime seconds 120 by default, 600 in old OpenSSH versions, then sshd's SIGALRM handler is called asynchronously. However, this signal handler calls various functions that are n...

K000140222: OpenSSH server vulnerability CVE-2024-6387

Security Advisory Description A security regression CVE-2006-5051 was discovered in OpenSSH's server sshd. There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a se...
