Security Bulletin

This security bulletin contains information about 3 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

Update the affected package go1.18 to the latest version.

2) Resource management error

EUVDB-ID: #VU72685

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-2022-41724

CWE-ID: CWE-399 - Resource Management Errors

Exploit availability: No

Description

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

The vulnerability exists due to improper management of internal resources in crypto/tls when handling large TLS handshake records. A remote attacker can send specially crafted data to the application and perform a denial of service (DoS) attack.

The vulnerability affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable session resumption (by setting Config.ClientSessionCache to a non-nil value), and TLS 1.3 servers which request client certificates (by setting Config.ClientAuth >= RequestClientCert).

Mitigation

Update the affected package go1.18 to the latest version.
