Security Bulletin

This security bulletin contains information about 8 vulnerabilities.

1) Resource management error

EUVDB-ID: #VU72685

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-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 golang-1.19 to the latest version.
