Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU64805

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-43565

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The 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.

Mitigation

Update the affected package containerd, docker to the latest version.

2) Security restrictions bypass

EUVDB-ID: #VU60972

Risk: Medium

CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N/E:P/RL:O/RC:C]

CVE-ID: CVE-2022-23648

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: Yes

Description

The 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.

Mitigation

Update the affected package containerd, docker to the latest version.
