Description
This security bulletin contains information about 2 secuirty vulnerabilities.
1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2022-41717)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to excessive memory growth when handling HTTP/2 server requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection.
2) Input validation error (CVE-ID: CVE-2022-41716)
The vulnerability allows a local user to execute arbitrary OS commands on the system.
The vulnerability exists due to insecure processing of unsanitized NUL values in syscall.StartProcess and os/exec.Cmd. A local user on the Windows operating system can set a specially crafted environment variable and execute arbitrary OS commands on the system.
