CVE-2022-24778
Description
A flaw was found in the imgcrypt library when checking the keys of an authorized user to access an encrypted image on systems where layers are not available and cannot run on the host architecture. This flaw allows an attacker to run an image without providing the previously decrypted keys.
Statement
Only Fedora is using the affected codebase. Hence, marking other products as of Low impact as they are using an affected version of 'imgcrypt' as a transitive dependency.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
