CVE
High
False Positivecmd/go: Code Execution via Crafted .syso Files and cgo Linker Inputs
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.
Component
Go toolchain (cmd/go)
Disclosed

Description
The
go command passed .syso files, direct linker inputs in #cgo LDFLAGS and
libraries in -L directories to the external linker without validating their format. A
malicious package could disguise a GNU ld linker script as a library, embed linker
options in Windows or macOS object files, or trigger LTO plugins, executing code or
injecting flags at link time. This is a build-time issue in the Go toolchain and does not
affect KrakenD.
