Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Type Confusion

EUVDB-ID: #VU58229

Risk: Low

CVSSv4.0: 0.4 [CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:N/VI:L/VA:N/SC:N/SI:L/SA:N/E:U/U:Clear]

CVE-ID: CVE-2021-41190

CWE-ID: CWE-843 - Type confusion

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the system.

The vulnerability exists due to a type confusion error. A remote authenticated attacker can pass specially crafted data to the application, trigger a type confusion error and interpret the resulting content differently.

Mitigation

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

Vulnerable software versions

SUSE Linux Enterprise Server for SAP Applications: 12-SP3 - 12-SP5

SUSE Linux Enterprise High Performance Computing: 12

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote authenticated user via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Input validation error

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

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.

3) Security restrictions bypass

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

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.

4) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU61600

Risk: Medium

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2022-24769

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to containers are incorrectly started with non-empty inheritable Linux process capabilities, which leads to security restrictions bypass and privilege escalation.

Mitigation
