Vulnerability Spotlight: Vulnerabilities in DaVinci Resolve video editing software could lead to code execution


Cisco Talos recently discovered two vulnerabilities in the DaVinci Resolve video editing software that could allow an adversary to execute code in the context of the application. 

DaVinci Resolve is a non-linear video editing application from Blackmagic Software that is available on multiple operating systems. Both these vulnerabilities exist in the DPDecoder service inside DaVinci Resolve.TALOS-2021-1426 (CVE-2021-40417) is a heap-based buffer overflow vulnerability that occurs when the application faces an integer overflow condition that leads to a sign extension while trying to decode a video file. Alternatively, TALOS-2021-1427 (CVE-2021-40418) could also lead to code execution, but is instead triggered as the result of an uninitialized object member as a result of an incorrect UUID. 

Cisco Talos worked with Blackmagic to ensure that these issues are resolved and an update is available for affected customers, all in adherence to Cisco’s vulnerability disclosure policy
