How to mitigate the Docker runc vulnerability In addition to the runc vulnerability, which was fixed in the newly released runc 1.1.12, McNamara also found container escape vulnerabilities in other Docker components such as BuildKit (CVE-2024-23652 and CVE-2024-23653) and a cache race ...
These vulnerabilities can only be exploited if a user actively engages with malicious content by incorporating it into the build process or running a container from a suspect image (particularly relevant for the CVE-2024-21626 container escape vulnerability). Potential impacts include unauthorized access...
