Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Incorrect authorization

EUVDB-ID: #VU64699

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-24778

CWE-ID: CWE-863 - Incorrect Authorization

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists in 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. A remote attacker can run an image without providing the previously decrypted keys and gain access to sensitive information.

Mitigation
