Summary
openssh security update
Details

An open source implementation of SSH protocol version 2

Security Fix(es):

sshd in OpenSSH before 10.4 allows remote attackers to cause a denial of service (resource consumption from excessive authentication attempts) because MaxAuthTries was mishandled for GSSAPIAuthentication.(CVE-2026-60000)

sshd in OpenSSH before 10.4 does not always honor the minimum authentication delay.(CVE-2026-60001)

ssh in OpenSSH before 10.4 can have a use-after-free when a server changes its host key during a key re-exchange. (This outcome occurs only on the client side.)(CVE-2026-60002)
