"The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced
in the ALINUX3-SA-2023:0055 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2023-29402:
    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-2023-29403:
    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-2023-29404:
    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. 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-2023-29405:
    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.
