golang.org/x/net contains a fix for CVE-2022-41717, which was addressed in stdlib in go1.19.4 and go1.18.9; > net/http: limit canonical header cache by bytes, not entries > > An attacker can 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. > > This issue is also fixed in golang.org/x/net/http2 v0.4.0, > for users manually configuring HTTP/2. full diff: https://github.com/golang/net/compare/v0.2.0...v0.4.0 other dependency updates (due to (circular) dependencies): - golang.org/x/sys v0.3.0: https://github.com/golang/sys/compare/3c1f35247d10...v0.3.0 - golang.org/x/text v0.5.0: https://github.com/golang/text/compare/v0.3.7...v0.5.0 Signed-off-by: Sebastiaan van Stijn <github@gone.nl>

// Package windows contains an interface to the low-level operating system
|
|
// primitives. OS details vary depending on the underlying system, and
|
|
// by default, godoc will display the OS-specific documentation for the current
|
|
// system. If you want godoc to display syscall documentation for another
|
|
// system, set $GOOS and $GOARCH to the desired system. For example, if
|
|
// you want to view documentation for freebsd/arm on linux/amd64, set $GOOS
|
|
// to freebsd and $GOARCH to arm.
|
|
//
|
|
// The primary use of this package is inside other packages that provide a more
|
|
// portable interface to the system, such as "os", "time" and "net". Use
|
|
// those packages rather than this one if you can.
|
|
//
|
|
// For details of the functions and data types in this package consult
|
|
// the manuals for the appropriate operating system.
|
|
//
|
|
// These calls return err == nil to indicate success; otherwise
|
|
// err represents an operating system error describing the failure and
|
|
// holds a value of type syscall.Errno.
