Vulnerability Report: GO-2021-0356
- CVE-2022-27191, GHSA-8c26-wmh5-6g9v
- Affects: golang.org/x/crypto
- Published: Apr 25, 2022
- Modified: Jun 22, 2023
Attackers can cause a crash in SSH servers when the server has been configured by passing a Signer to ServerConfig.AddHostKey such that 1) the Signer passed to AddHostKey does not implement AlgorithmSigner, and 2) the Signer passed to AddHostKey returns a key of type “ssh-rsa” from its PublicKey method. Servers that only use Signer implementations provided by the ssh package are unaffected.
