Description

This security bulletin contains information about 2 vulnerabilities.


1) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2022-41717)

CWE-ID: CWE-770 - Allocation of Resources Without Limits or Throttling

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Green


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) Path traversal (CVE-ID: CVE-2022-41720)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to the way os.DirFS function and http.Dir type handle empty values on Windows, allowing an attacker with control over the path to view arbitrary files on the system.
