dstack has insecure LUKS2 persistent storage partitions that may be opened and used

dstack is a software development kit (SDK) to simplify the deployment of arbitrary containerized apps into trusted execution environments. In versions of dstack prior to 0.5.4, a malicious host may provide a crafted LUKS2 data volume to a dstack CVM for use as the `/data` mount. The guest will open the volume and write secret data using a volume key known to the attacker, causing disclosure of Wireguard keys and other secret information. The attacker can also pre-load data on the device, which could potentially compromise guest execution. LUKS2 volume metadata is not authenticated and supports null key-encryption algorithms, allowing an attacker to create a volume such that the volume opens (cryptsetup open) without error using any passphrase or token, records all writes in plaintext (or ciphertext with an attacker-known key), and/or contains arbitrary data chosen by the attacker. Version 0.5.4 of dstack contains a patch that addresses LUKS headers.

dstack 安全漏洞

dstack是Dstack TEE开源的一个TEE部署工具。 dstack 0.5.4之前版本存在安全漏洞，该漏洞源于恶意主机可能提供特制LUKS2数据卷，导致Wireguard密钥和其他秘密信息泄露，并可能破坏客户机执行。
