CVE-2024-24793

Estado: ModificadaCrítica (9.8)—

A use-after-free vulnerability exists in the DICOM Element Parsing as implemented in Imaging Data Commons libdicom 1.0.5. A specially crafted DICOM file can cause premature freeing of memory that is used later. To trigger this vulnerability, an attacker would need to induce the vulnerable application to process a malicious DICOM image.The Use-After-Free happens in the `parse_meta_element_create()` parsing the elements in the File Meta Information header.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).
