  • CVE-2022-30629: A flaw was found in the crypto/tls golang package. When session tickets are generated by crypto/tls, it is missing the ticket expiration. This issue may allow an attacker to observe the TLS handshakes to correlate successive connections during session resumption.
  • CVE-2022-41717: A flaw was found in the net/http library of the golang package. This flaw allows an attacker to cause excessive memory growth in a Go server accepting HTTP/2 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.

CVE-2022-41720: [security] Go 1.19.4 and Go 1.18.9 are released

On Windows, restricted files can be accessed via os.DirFS and http.Dir. The os.DirFS function and http.Dir type provide access to a tree of files rooted at a given directory. These functions permit access to Windows device files under that root. For example, os.DirFS("C:/tmp").Open("COM1") opens the COM1 device. Both os.DirFS and http.Dir only provide read-only filesystem access. In addition, on Windows, an os.DirFS for the directory (the root of the current drive) can permit a maliciously crafted path to escape from the drive and access any path on the system. With fix applied, the behavior of os.DirFS("") has changed. Previously, an empty root was treated equivalently to "/", so os.DirFS("").Open("tmp") would open the path "/tmp". This now returns an error.
