Missing validation of offset and count parameters in the g_buffered_input_stream_peek() function can lead to an integer overflow during length calculation. When specially crafted values are provided, this overflow results in an incorrect size being passed to memcpy(), triggering a buffer overflow. This can cause application crashes, leading to a Denial of Service (DoS).\n\n## Affected\n\n- `glib2-main (all versions)`\n- `bootc (all versions)`\n- `glib2 (all versions)`\n- `glycin-loaders (all versions)`\n- `loupe (all versions)`\n- `mingw-glib2 (all versions)`\n- `papers (all versions)`\n- `rpm-ostree (all versions)`\n- `glib2 (all versions)`\n- `glib2 (all versions)`\n- `glib2 (all versions)`\n- `librsvg2 (all versions)`\n- `mingw-glib2 (all versions)`\n- `bootc (all versions)`\n- `glib2 (all versions)`\n- `librsvg2 (all versions)`\n- `mingw-glib2 (all versions)`\n- `rhoai/odh-ai-gateway-operator-rhel9`\n- `rhoai/odh-core-bff-rhel9`\n- `rhoai/odh-dashboard-operator-rhel9`\n- `rhoai/odh-dashboard-rhel9`\n- `rhoai/odh-data-science-pipelines-operator-controller-rhel9`\n- `rhoai/odh-kf-notebook-controller-rhel9`\n- `rhoai/odh-kserve-controller-rhel9`\n- `rhoai/odh-kserve-llmisvc-controller-rhel9`\n- `rhoai/odh-kserve-module-operator-rhel9`\n- `rhoai/odh-kuberay-operator-controller-rhel9`\n- `rhoai/odh-kube-rbac-proxy-rhel9`\n- `rhoai/odh-llama-stack-k8s-operator-rhel9`\n- `rhoai/odh-maas-controller-rhel9`\n- `rhoai/odh-mlflow-operator-rhel9`\n- `rhoai/odh-mlflow-rhel9`\n- `rhoai/odh-mod-arch-agent-ops-rhel9`\n- `rhoai/odh-mod-arch-automl-rhel9`\n- `rhoai/odh-mod-arch-autorag-rhel9`\n- `rhoai/odh-mod-arch-eval-hub-rhel9`\n- `rhoai/odh-mod-arch-gen-ai-rhel9`\n- `rhoai/odh-mod-arch-maas-rhel9`\n- `rhoai/odh-mod-arch-mlflow-rhel9`\n- `rhoai/odh-mod-arch-model-registry-rhel9`\n- `rhoai/odh-model-controller-rhel9`\n- `rhoai/odh-model-registry-operator-rhel9`\n- `rhoai/odh-model-serving-api-rhel9`\n- `rhoai/odh-notebook-controller-rhel9`\n- `rhoai/odh-ogx-k8s-operator-rhel9`\n- `rhoai/odh-ogx-module-operator-rhel9`\n- `rhoai/odh-training-operator-rhel9`\n- `rhoai/odh-trustyai-service-operator-rhel9`\n- `rhoai/odh-workbenches-operator-rhel9`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nMitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.","depth":"sunlit","depthScore":20,"depthScoreParts":{"impact":20.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
