A vulnerability was detected in HdrHistogram up to 2.2.2. Affected by this issue is the function org.HdrHistogram.AbstractHistogram.decodeFromCompressedByteBuffer of the file src/main/java/org/HdrHistogram/AbstractHistogram.java. The manipulation of the argument lengthOfCompressedContents results in uncontrolled memory allocation. The attack needs to be approached locally. The exploit is now public and may be used. The project was informed of the problem early through an issue report but has not responded yet.
AI BU triage note: The upstream HdrHistogram project closed the referenced GitHub issue (https://github.com/HdrHistogram/HdrHistogram/issues/219) as 'BOGUS/SPAM FAKE CVE Report'. NVD status is 'Deferred'. Red Hat CVSS is 3.3/LOW. Pre-existing OSIDB affects on odh-model-registry-job-async-upload-rhel9 and odh-llm-d-inference-scheduler-rhel9 were set to NOTAFFECTED (Vulnerable Code not Present): those images ship the Rust hdrhistogram crate (7.5.4, cargo), which is a separate implementation unaffected by this Java-specific flaw (AbstractHistogram.java:2275-2281, decodeFromCompressedByteBuffer). New AFFECTED/DEFER affects were created for odh-trustyai-service-rhel9 and odh-workbench-jupyter-trustyai-cpu-py312-rhel9 across rhoai-2.25, rhoai-3.3, rhoai-3.4, which ship org.hdrhistogram/HdrHistogram 2.1.12 (Maven, in range per CVE reporter's claim of '2.2.2 and earlier'). No trackers filed (LOW/DEFER).
