When performing this operation, the initial validation of the source `/dev/null` was insufficient. Specifically, we initially failed to verify whether `/dev/null` was genuinely present. However, we did perform validation to ensure that the `/dev/null` path existed within the container, including checking for symbolic links. Additionally, there was a vulnerability in the timing between validation and the actual mount operation.</p> <p>As a result, by replacing `/dev/null` with a symbolic link, we can bind-mount arbitrary files from the host system.</p> <p>This is a different project, but the core logic is similar to the CVE in runc. Issues were identified in runc, and verification was also conducted in youki to confirm the problems. https://github.com/opencontainers/runc/security/advisories/GHSA-9493-h29p-rfm2</p> <p>### Credits</p> <p>Thanks to Lei Wang (@ssst0n3 from Huawei) for finding and reporting the original runc&#39;s vulnerability (Attack 1), and Li Fubang (@lifubang from acmcoder.com, CIIC) for discovering another attack vector in runc (Attack 2) based on @ssst0n3&#39;s initial findings.</p> <p>Also, @cyphar helped youki in finding the problem.</p> <p><strong>Affected:</strong> crates.io: youki</p> <p>### Impact ###</p> <p>youki utilizes bind mounting the container&#39;s `/dev/null` as a file mask.
