ArchLinux: 201710-16: go-pie: arbitrary command execution
Summary
Go before 1.8.4 and 1.9.x before 1.9.1 allows "go get" remote command execution. Using custom domains, it is possible to arrange things so that /pkg1 points to a Subversion repository but /pkg1/pkg2 points to a Git repository. If the Subversion repository includes a Git checkout in its pkg2 directory and some other work is done to ensure the proper ordering of operations, "go get" can be tricked into reusing this Git checkout for the fetch of code from pkg2. If the Subversion repository's Git checkout has malicious commands in .git/hooks/, they will execute on the system running "go get".
Resolution
Upgrade to 2:1.9.1-1.
# pacman -Syu "go-pie>=2:1.9.1-1"
The problem has been fixed upstream in version 1.9.1.
