Security Bulletin

This security bulletin contains information about 4 vulnerabilities.

1) Resource exhaustion

EUVDB-ID: #VU72686

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-2022-41723

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to application does not properly control consumption of internal resources in the HPACK decoder. A remote attacker can send a specially crafted HTTP/2 stream to the application, cause resource exhaustion and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

openEuler: 22.03 LTS SP1

cri-o-debugsource: before 1.23.2-11

cri-o-debuginfo: before 1.23.2-11

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker 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: #VU70478

Risk: Low

CVSSv3.1: 4.1 [CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:U/C:L/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-4318

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a local user to bypass certain security restrictions.

The vulnerability exists due to improper input validation when handling newline characters in environment variables. A local user can create a specially crafted environment variable and add entries to a container's /etc/passwd. It is also possible to circumvent admission validation of username/UID by adding such an entry.

Mitigation

Install updates from vendor's repository.

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

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

3) Resource exhaustion

EUVDB-ID: #VU82064

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-2023-39325

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to excessive consumption of internal resources when handling HTTP/2 requests. A remote attacker can bypass the http2.Server.MaxConcurrentStreams setting by creating new connections while the current connections are still being processed, trigger resource exhaustion and perform a denial of service (DoS) attack.

Mitigation

Install updates from vendor's repository.

4) Inadequate encryption strength

EUVDB-ID: #VU84537

Risk: Low

CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-48795

CWE-ID: CWE-326 - Inadequate Encryption Strength

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to incorrect implementation of the SSH Binary Packet Protocol (BPP), which mishandles the handshake phase and the use of sequence numbers. A remote attacker can perform MitM attack and delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5.

The vulnerability was dubbed "Terrapin attack" and it affects both client and server implementations.

Mitigation

Install updates from vendor's repository.
