Prior to version 0.9.0, Boxlite allows users to specify the OCI image used by containers in the sandbox. However, when processing tar entries in OCI images, Boxlite does not account for the possibility that entries may be symlinks pointing to absolute paths. An attacker can craft a malicious OCI image and distribute it on image hosting platforms such as DockerHub, tricking users into using it. Once a user loads the malicious image, the attacker can write arbitrary content to any path on the host, which can further lead to remote code execution on the host. This issue has been patched in version 0.9.0."},{"lang":"es","value":"Boxlite es un servicio de sandbox que permite a los usuarios crear máquinas virtuales ligeras (Boxes) y lanzar contenedores OCI dentro de ellas para ejecutar código no confiable.
