"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 example.com/pkg1 points to a Subversion repository but
example.com/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.'

For Debian 7 'Wheezy', these problems have been fixed in version
2:1.0.2-1.1+deb7u2.

We recommend that you upgrade your golang packages.

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