EulerOS 2.0 SP11 : golang (EulerOS-SA-2023-2842)

critical Nessus Plugin ID 188895

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the golang packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected golang packages.
