Alpine: multiple go packages: security update to 1.20.5-r0

critical Tenable Self-Hosted Container Security Plugin ID 404781

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- The go command may generate unexpected code at build time when using cgo. This may result in unexpected
behavior when running a go program which uses cgo. This may occur when running an untrusted module which
contains directories with newline characters in their names. Modules which are retrieved using the go
command, i.e. via "go get", are not affected (modules retrieved using GOPATH-mode, i.e. GO111MODULE=off,
may be affected). (CVE-2023-29402)

- On Unix platforms, the Go runtime does not behave differently when a binary is run with the setuid/setgid
bits. This can be dangerous in certain cases, such as when dumping memory state, or assuming the status of
standard i/o file descriptors. If a setuid/setgid binary is executed with standard I/O file descriptors
closed, opening any files can result in unexpected content being read or written with elevated privileges.
Similarly, if a setuid/setgid program is terminated, either via panic or signal, it may leak the contents
of its registers. (CVE-2023-29403)

- The go command may execute arbitrary code at build time when using cgo. This may occur when running "go
get" on a malicious module, or when running any other command which builds untrusted code. This is can by
triggered by linker flags, specified via a "#cgo LDFLAGS" directive. The arguments for a number of flags
which are non-optional are incorrectly considered optional, allowing disallowed flags to be smuggled
through the LDFLAGS sanitization. This affects usage of both the gc and gccgo compilers. (CVE-2023-29404)

- The go command may execute arbitrary code at build time when using cgo. This may occur when running "go
get" on a malicious module, or when running any other command which builds untrusted code. This is can by
triggered by linker flags, specified via a "#cgo LDFLAGS" directive. Flags containing embedded spaces are
mishandled, allowing disallowed flags to be smuggled through the LDFLAGS sanitization by including them in
the argument of another flag. This only affects usage of the gccgo compiler. (CVE-2023-29405)
