openssh: Heap out-of-bounds read in Red Hat Enterprise Linux versions of OpenSSH GSSAPI indicator cleanup due to missing NULL sentinel termination
A flaw was found in OpenSSH. This vulnerability, a heap out-of-bounds read, occurs during the cleanup of GSSAPI Generic Security Service Application Programming Interface indicators when a trailing NULL termination is missing in the auth-indicators array. A remote attacker, under specific...
openssh: Double free in Red Hat Enterprise Linux versions of OpenSSH DH-GEX client path during FIPS known-group validation leads to client-side denial of service
A flaw was found in OpenSSH. A malicious SSH server can exploit a double free vulnerability in the Diffie-Hellman Group Exchange DH-GEX client path. This occurs during FIPS Federal Information Processing Standards mode known-group validation when the client processes attacker-controlled DH-GEX...

CVE-2026-59995
A flaw was found in OpenSSH. The sftp client, when used to download files from a malicious server with the 'sftp server:/path .' command, does not properly restrict where those files are saved. This allows an attacker to control the download location, potentially overwriting existing files or...
CVE-2026-59997
A flaw was found in OpenSSH. The internal-sftp component within sshd incorrectly processes command-line arguments, recognizing only the first nine. This limitation can prevent the application of intended security configurations for SFTP SSH File Transfer Protocol connections, potentially leading ...
CVE-2026-59998
A flaw was found in OpenSSH. The sshd component has an undocumented security-relevant behavior where GSSAPIStrictAcceptorCheck has no value when the server is in a Windows Active Directory environment. This could lead to unintended information disclosure and impact data integrity. Mitigation To...
CVE-2026-60001
A flaw was found in OpenSSH's SSH daemon sshd. A remote attacker could exploit this vulnerability by repeatedly attempting authentication. The flaw allows the attacker to bypass the intended minimum authentication delay, which can facilitate brute-force attacks. This makes it easier for an attack...
CVE-2026-60002
A flaw was found in OpenSSH. A remote attacker could exploit a use-after-free vulnerability on the client side when a server changes its host key during a key re-exchange. This could lead to high impact on confidentiality and integrity, and low impact on availability. Mitigation To mitigate this...
CVE-2026-59999
A flaw was found in sshd, the OpenSSH server daemon. When DisableForwarding=yes is configured to prevent network traffic forwarding, it incorrectly fails to take precedence over PermitTunnel=yes. This allows a remote attacker to bypass intended security restrictions and establish a tunnel,...
CVE-2026-60000
A flaw was found in OpenSSH's Secure Shell Daemon sshd. This vulnerability allows a remote attacker to cause a denial of service by initiating an excessive number of authentication attempts. The issue arises from the mishandling of the MaxAuthTries setting specifically when using...
Allocation of Resources Without Limits or Throttling
Overview Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to improper handling of the MaxAuthTries parameter during the authentication process. An attacker can exhaust server resources by repeatedly attempting authentication using GSSAPI...
