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
computer.

CVE-2017-15041

     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."

CVE-2018-16873

    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.

CVE-2018-16874

    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
    execution.

CVE-2019-9741

    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
    command.

CVE-2019-16276

    Go allows HTTP Request Smuggling.

CVE-2019-17596

    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
    certificates.

CVE-2021-3114

    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
1.7.4-2+deb9u3.

We recommend that you upgrade your golang-1.7 packages.
