openssh-9.9p1-13.el9_8.ML.1

OpenSSH is an SSH protocol implementation supported by a number of Linux, UNIX, and similar operating systems. It includes the core files necessary for both the OpenSSH client and server.

Security Fix(es):

* openssh: OpenSSH: SFTP security bypass due to command-line argument parsing flaw (CVE-2026-59997)
* openssh: OpenSSH: Undocumented GSSAPIStrictAcceptorCheck behavior impacts security in Windows Active Directory (CVE-2026-59998)
* openssh: OpenSSH: Denial of Service via excessive GSSAPI authentication attempts (CVE-2026-60000)

CVE-2026-59997
internal-sftp in sshd in OpenSSH before 10.4 recognizes only the first 9 command-line arguments, which can be important if a later command-line argument would have helped to ensure the intended security properties of an SFTP connection.
CVE-2026-59998
sshd in OpenSSH before 10.4 has an undocumented security-relevant behavior: GSSAPIStrictAcceptorCheck has no value if the server is in Windows Active Directory.
CVE-2026-60000
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.
