Title
ALAS-2023-1825 -- обновление безопасности для amazon-ssm-agent
Description
The x/crypto/ssh package before 0.0.0-20211202192323-5770296d904e of golang.org/x/crypto allows an attacker to panic an SSH server. (CVE-2021-43565)
A broken cryptographic algorithm flaw was found in golang.org/x/crypto/ssh. This issue causes a client to fail authentification with RSA keys to servers that reject signature algorithms based on SHA-2, enabling an attacker to crash the server, resulting in a loss of availability. (CVE-2022-27191)
In net/http in Go before 1.18.6 and 1.19.x before 1.19.1, attackers can cause a denial of service because an HTTP/2 connection can hang during closing if shutdown were preempted by a fatal error. (CVE-2022-27664)
