Overview

CVE-2021-40417 is a critical-severity vulnerability. It was published on December 22, 2021 and has a CVSS 3.1 base score of 9.8 (CRITICAL).

This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

When parsing a file that is submitted to the DPDecoder service as a job, the service will use the combination of decoding parameters that were submitted with the job along with fields that were parsed for the submitted video by the R3D SDK to calculate the size of a heap buffer. Due to an integer overflow with regards to this calculation, this can result in an undersized heap buffer being allocated. When this heap buffer is written to, a heap-based buffer overflow will occur. This can result in code execution under the context of the application.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
