Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Incorrect authorization
EUVDB-ID: #VU64699
Risk: Medium
CVSSv3.1: 5.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-24778
CWE-ID:
CWE-863 - Incorrect Authorization
Exploit availability: No
DescriptionThe 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.
MitigationInstall updates from vendor's website.
