By nesting a git checkout inside another version control repository, it was possible for an attacker to trick the “go get” command into executing arbitrary code. The go command now refuses to use version control checkouts found inside other version control systems, with an exception for git submodules (git inside git).
The issue is tracked as https://golang.org/issue/22125 (Go 1.8.4) and https://golang.org/issue/22131 (Go 1.9.1). Fixes are linked from the issues.


In the smtp package, PlainAuth is documented as sending credentials only over authenticated, encrypted TLS connections, but it was changed in Go 1.1 to also send credentials on non-TLS connections when the remote server advertises that PLAIN authentication is supported. The change was meant to allow use of PLAIN authentication on localhost, but it has the effect of allowing a man-in-the-middle attacker to harvest credentials. PlainAuth now requires either TLS or a localhost connection before sending credentials, regardless of what the remote server claims.
This issue is tracked as https://golang.org/issue/22134 (Go 1.8.4) and https://golang.org/issue/22133 (Go 1.9.1). Fixes are linked from the issues.
