Security readout for executives and security teams
Plain-English summary
Grassroot DICOM 3.0.23 can corrupt memory while decoding JPEG2000 content in a specially crafted DICOM file. Successful exploitation could compromise confidentiality, integrity, and availability. Automated systems accepting DICOM files from external or untrusted sources face the greatest business risk.
Executive priority
Treat this as a high-priority remediation for externally exposed or automated medical-image ingestion systems. Immediate emergency action is less supported for isolated systems because exploitation requires a crafted file and high attack complexity, with no active-exploitation evidence supplied.
Technical view
CVE-2024-22373 is an out-of-bounds write in JPEG2000Codec::DecodeByStreamsCommon. A crafted DICOM file can cause a heap buffer overflow. CVSS 3.1 rates it 8.1: network-accessible, no privileges or user interaction required, but high attack complexity, with potentially high impact across all three security objectives.
Likely exposure
Confirmed scope in the bundle is Grassroot DICOM 3.0.23. Prioritize systems that use this version to decode attacker-controlled DICOM or JPEG2000 data, particularly automated or network-facing ingestion services. The supplied evidence does not establish whether other versions are affected.
Exploitation context
An attacker must provide a specially crafted DICOM file that reaches the vulnerable decoding path. Attack complexity is rated high. The bundle does not report public exploitation, and the CVE is not identified as being in CISA's KEV catalog.
Researcher notes
The vulnerability is classified under CWE-119 and affects heap memory during JPEG2000 decoding. Potential impact is broad, but the bundle does not establish reliable code execution, observed attacks, fixed upstream versions, or the complete affected-version range. Avoid extending scope beyond version 3.0.23 without additional vendor evidence.
Mitigation direction
- Identify and prioritize every deployment or dependency using Grassroot DICOM 3.0.23.
- Check Talos, vendor, and distribution guidance for an approved corrected package or release.
- Until corrected, restrict processing of DICOM files from untrusted or external sources.
- Isolate affected decoding services and minimize their privileges and access to sensitive systems.
Validation and detection
- Confirm deployed Grassroot DICOM versions, including embedded and transitive application dependencies.
- Map which services accept DICOM files and whether external parties can submit them.
- Verify remediation against the vendor or distribution package version specified in published guidance.
- Review crashes and memory-corruption indicators associated with DICOM or JPEG2000 decoding.

Improper Restriction of Operations within the Bounds of a Memory Buffer
Improper Restriction of Operations within the Bounds of a Memory Buffer represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
