Important: openssh security update
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: Local MITM of X11 forwarding via abstract UNIX socket pre-binding in Rocky Linux OpenSSH client versions (CVE-2026-55655)
-
openssh: Double free in Rocky Linux versions of OpenSSH DH-GEX client path during FIPS known-group validation leads to client-side denial of service (CVE-2026-55653)
-
openssh: Heap out-of-bounds read in Rocky Linux versions of OpenSSH GSSAPI indicator cleanup due to missing NULL sentinel termination (CVE-2026-55654)
-
openssh: OpenSSH: Use-after-free vulnerability during host key re-exchange on the client side (CVE-2026-60002)
-
openssh: OpenSSH:
scpfile misplacement vulnerability during remote copy (CVE-2026-59996)

Связанные уязвимости
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 configurations involving GSSAPI authentication and a Kerberos environment, could exploit this to cause the SSH authentication path to crash or abort. This leads to a denial of service (DoS), impacting the availability of the SSH service.
