CVE
High
False Positivecmd/go: Command Execution via GCC Spec Files in cgo Linker Search Directories
This advisory does not affect KrakenD
This is a build-time vulnerability in the Go toolchain (
cmd/go) that requires
compiling a malicious package. KrakenD distributes pre-compiled binaries and never
invokes the Go toolchain at runtime, so the gateway is not exposed. If you compile
KrakenD Enterprise plugins, build them with the krakend/builder-ee image of version
3.0.4 or 2.13.14, which ships the fixed toolchain.Addressed through routine dependency maintenance in CE 3.0.4 and EE 3.0.4, 2.13.14.

Description
When building with GCC, a malicious package that uses cgo could run arbitrary commands
at link time through untrusted GCC spec files. Linking with
-fopenmp, -fopenacc or
-fsanitize= makes GCC search for spec files in the -L and sysroot directories, and in
some cases in the working directory, so a package could ship its own. This is a
build-time issue in the Go toolchain and does not affect KrakenD.
