CVE-2022-24778 – Incorrect Authorization in imgcrypt

https://notcve.org/view.php?id=CVE-2022-24778

The imgcrypt library provides API exensions for containerd to support encrypted container images and implements the ctd-decoder command line tool for use by containerd to decrypt encrypted container images. The imgcrypt function `CheckAuthorization` is supposed to check whether the current used is authorized to access an encrypted image and prevent the user from running an image that another user previously decrypted on the same system. In versions prior to 1.1.4, a failure occurs when an image with a ManifestList is used and the architecture of the local host is not the first one in the ManifestList. Only the first architecture in the list was tested, which may not have its layers available locally since it could not be run on the host architecture. Therefore, the verdict on unavailable layers was that the image could be run anticipating that image run failure would occur later due to the layers not being available. • https://github.com/containerd/imgcrypt/commit/6fdd9818a4d8142107b7ecd767d839c9707700d9 https://github.com/containerd/imgcrypt/issues/69 https://github.com/containerd/imgcrypt/releases/tag/v1.1.4 https://github.com/containerd/imgcrypt/security/advisories/GHSA-8v99-48m9-c8pm https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4SJUNSC7YZLA745EMKWK2GKEV57GE52K https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TAHAAOOA3KZJC2I5WHCR3XVBJBNWTWUE https://lists.fe • CWE-303: Incorrect Implementation of Authentication Algorithm CWE-863: Incorrect Authorization •
