Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:4923-1 advisory.

 - CVE-2026-39882: go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracehttp: Memory exhaustion via uncapped HTTP response body reading (bsc#1274214).
 - CVE-2026-47262: Denial of Service (DoS) condition via a maliciously crafted image (bsc#1268441).
 - CVE-2026-53493: a crafted OCI index graph can force very high CPU/memory usage during PullImage (before container start), causing long ContainerCreating stalls and, at larger sizes, node/runtime instability (bsc#1282669).
 - CVE-2026-53495: CRI ExecSync Goroutine Leak Leads to Node-Level Denial of Service (bsc#1280007).
 - CVE-2026-95838: github.com/containerd/containerd: processing of certain image layers causes superlinear time complexity in unpack handler and can lead to DoS (bsc#1285124).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
