A medium severity heap out-of-bounds read vulnerability (CVE-2026-2303) was found in the GSSAPI error handling of the go.mongodb.org mongo-driver dependency used by Apptainer. The vulnerability is addressed by removing this dependency in a security update for the alloy component. The update also adds support for building the SUID starter on SLES 15. A patch is available for affected versions.

Multiple security issues were addressed in the trivy-0.75.0-1.1 package for openSUSE Tumbleweed, affecting the SUSE trivy product version 0.74.0-160000.3.1. These vulnerabilities impact the containerd container runtime across various Ubuntu package versions. The issues have been fixed in the updated trivy package version 0.75.0-1.1. There are no known exploits in the wild at this time.

A security update for the keybase-client addresses multiple vulnerabilities including authentication bypass and deadlocks in the crypto/ssh library. The update involves patching the affected crypto dependency and upgrading to Go 1.26 to incorporate the updated crypto library. These vulnerabilities are identified by CVE-2026-56854, CVE-2026-56855, and CVE-2026-78662. The issues could potentially allow bypassing authentication mechanisms and cause deadlocks, impacting the reliability and security of the client.

This security update for the hauler component addresses multiple vulnerabilities including authentication bypass and deadlocks in the golang.org/x/crypto/ssh library, as well as denial of service (DoS) issues in google.golang.org/grpc caused by missing ':authority' and 'Host' headers. The update advances hauler to version 2.1.0 and fixes several CVEs (CVE-2026-41888, CVE-2026-56854, CVE-2026-56855, CVE-2026-78662, CVE-2026-84303, CVE-2026-84304, CVE-2026-84445). The vulnerabilities are rated critical and a patch is available. No known exploits in the wild have been reported.

This security update for the Trivy tool addresses multiple vulnerabilities across several dependencies, including improper certificate validation, HTTP method override bypass, denial of service via oversized inputs, information disclosure through crafted tarball hardlinks, authentication bypass and deadlocks in SSH libraries, authorization bypass due to header case mismatches, heap memory exhaustion, and denial of service from missing headers in gRPC servers. These issues collectively pose risks ranging from low to potentially higher impact depending on context. The update fixes these issues to improve overall security.

CVE-2026-78662 is a high-severity vulnerability in the golang.org/x/crypto/ssh package. It allows a malicious peer to flood incoming requests on a channel before it is fully established, causing a deadlock of the entire connection. The root cause is the lack of limits or throttling on resource allocation for channels registered but not yet usable. The vulnerability is addressed by adding an atomic established state to drop packets other than open confirmation or failure until the channel is usable, preventing blocking or connection teardown.

The source-address critical option in the Permissions returned by an authentication callback was only enforced for the PublicKeyCallback and VerifiedPublicKeyCallback paths, extending the fix for CVE-2026-46595. Permissions returned by the PasswordCallback, KeyboardInteractiveCallback, NoClientAuthCallback, and GSSAPIWithMICConfig.AllowLogin callbacks were not validated against the client's remote address, so a source-address restriction set by those callbacks was silently ignored. The check is now applied to the Permissions returned by any authentication callback.
