Bug 802054 (CVE-2021-34558) – <dev-lang/go-{1.15.14,1.16.6}: Denial of service in crypto/tls (CVE-2021-34558)

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description Sam James 2021-07-13 20:18:58 UTC]

Description:
"crypto/tls clients can panic when provided a certificate of the wrong type for the negotiated parameters.
net/http clients performing HTTPS requests are also affected. The panic can be triggered by an attacker
in a privileged network position without access to the server certificate's private key, as long as a trusted
ECDSA or Ed25519 certificate for the server exists (or can be issued), or the client is configured with
Config.InsecureSkipVerify. Clients that disable all TLS_RSA cipher suites (that is, TLS 1.0–1.2 cipher
suites without ECDHE), as well as TLS 1.3-only clients, are unaffected.

This is issue #47143 and CVE-2021-34558. Thanks to Imre Rad for reporting this issue."

Please bump to 1.15.14, 1.16.6.
