Debian Bug     : 924630 941173 942628 942629

Several vulnerabilities were discovered in the Go programming
language. An attacker could trigger a denial-of-service (DoS), bypasss
access control, and execute arbitrary code on the developer's


     Go 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."


    The "go get" command is vulnerable to remote code execution when
    executed with the -u flag and the import path of a malicious Go
    package, as it may treat the parent directory as a Git repository
    root, containing malicious configuration.


    The "go get" command is vulnerable to directory traversal when
    executed with the import path of a malicious Go package which
    contains curly braces (both '{' and '}' characters). The attacker
    can cause an arbitrary filesystem write, which can lead to code


    In net/http, CRLF injection is possible if the attacker controls a
    url parameter, as demonstrated by the second argument to
    http.NewRequest with \r\n followed by an HTTP header or a Redis


    Go allows HTTP Request Smuggling.


    Go can panic upon an attempt to process network traffic containing
    an invalid DSA public key. There are several attack scenarios,
    such as traffic from a client to a server that verifies client


    crypto/elliptic/p224.go can generate incorrect outputs, related to
    an underflow of the lowest limb during the final complete
    reduction in the P-224 field.

For Debian 9 stretch, these problems have been fixed in version

We recommend that you upgrade your golang-1.7 packages.
