CVE-2021-41190 – Clarify Content-Type handling in OCI spec

https://notcve.org/view.php?id=CVE-2021-41190

The OCI Distribution Spec project defines an API protocol to facilitate and standardize the distribution of content. In the OCI Distribution Specification version 1.0.0 and prior, the Content-Type header alone was used to determine the type of document during push and pull operations. Documents that contain both “manifests” and “layers” fields could be interpreted as either a manifest or an index in the absence of an accompanying Content-Type header. If a Content-Type header changed between two pulls of the same digest, a client may interpret the resulting content differently. The OCI Distribution Specification has been updated to require that a mediaType value present in a manifest or index match the Content-Type header used during the push and pull operations. • http://www.openwall.com/lists/oss-security/2021/11/19/10 https://github.com/opencontainers/distribution-spec/commit/ac28cac0557bcd3084714ab09f9f2356fe504923 https://github.com/opencontainers/distribution-spec/security/advisories/GHSA-mc8v-mgrf-8f4m https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/3TUZNDAH2B26VPBK342UC3BHZNLBUXGX https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4334HT7AZPLWNYHW4ARU6JBUF3VZJPZN https://lists.fedoraproject.org/archives/list/packa • CWE-843: Access of Resource Using Incompatible Type ('Type Confusion') •
