Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU64805
Risk: Medium
CVSSv4.0: 6.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]
CVE-ID: CVE-2021-43565
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when parsing a Signer to ServerConfig.AddHostKey in cases where the Signer passed to AddHostKey does not implement AlgorithmSigner or the Signer passed to AddHostKey returns a key of type “ssh-rsa” from its PublicKey method. A remote attacker can pass specially crafted input to the application and perform a denial of service (DoS) attack.
MitigationUpdate the affected package containerd, docker to the latest version.

EUVDB-ID: #VU60972
Risk: Medium
CVSSv4.0: 5.5 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:P/U:Green]
CVE-ID: CVE-2022-23648
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to an error when handling specially crafted image configuration in containerd where containers launched through containerd’s CRI implementation. A remote attacker can bypass any policy-based enforcement on container setup and access the read-only copies of arbitrary files and directories on the host.
MitigationUpdate the affected package containerd, docker to the latest version.

CVE-ID: CVE-2022-24769
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to escalate privileges on the system.
