Summary
Red Hat Security Advisory: Updated Red Hat OpenStack Platform 16.2 director Operator container images
Severity
Important
Notes
Topic: Updated container images are now available for director Operator for Red Hat OpenStack Platform 16.2 (Train) for RHEL 8.4.
Details: Red Hat OpenStack Platform provides the facilities for building, deploying and monitoring a private or public infrastructure-as-a-service (IaaS) cloud running on commonly available physical hardware. The Red Hat OpenStack Platform (RHOSP) director Operator adds the ability to install and run a RHOSP cloud within OpenShift Container Platform (OCP). Security Fixes: * golang.org/x/crypto/ssh: Denial of Service via crafted public key with excessive parameters (CVE-2026-39829) * golang.org/x/crypto/ssh: Denial of Service via resource leak from unsolicited SSH responses (CVE-2026-39830) * golang.org/x/crypto/ssh: Denial of Service via crafted AES-GCM packet decoder inputs (CVE-2026-46597)

CVE-2026-39829

A flaw was found in golang.org/x/crypto/ssh. The RSA and DSA public key parsers in the affected component did not enforce size limits on key parameters. This vulnerability allows an unauthenticated client to provide a crafted public key with an excessively large modulus or DSA parameter during public key authentication. Successful exploitation could lead to a denial of service (DoS) due to prolonged CPU consumption during signature verification.

Threats
Impact Important
CVE-2026-39830

A flaw was found in golang.org/x/crypto/ssh. A remote malicious SSH peer can exploit this by sending unsolicited global request responses, which fills an internal buffer and blocks the connection's read loop. This prevents the associated resources from being released, leading to a resource leak per connection. The consequence is a Denial of Service (DoS) for the affected system.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CWE-772 - Missing Release of Resource after Effective Lifetime
Affected products

Impact Important
CVE-2026-46597

A flaw was found in golang.org/x/crypto/ssh. A remote attacker could send specially crafted inputs to the AES-GCM packet decoder. This could lead to an incorrectly placed cast from bytes to an integer, causing a server-side panic and resulting in a Denial of Service (DoS) for the affected system.

7.5 (High)
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
