Amazon Linux 2 Security Advisory: ALAS-2021-1694
Advisory Release Date: 2021-08-04 20:32 Pacific
Advisory Updated Date: 2021-08-05 21:15 Pacific
A vulnerability was found in archive/zip of the Go standard library. Applications written in Go can panic or potentially exhaust system memory when parsing malformed ZIP files. (CVE-2021-33196)
A flaw was found in golang. A 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. (CVE-2021-34558)
