Specifically, it is only vulnerable in GOPATH mode, but not in module mode (the distinction is documented at https://golang.org/cmd/go/#hdr-Module_aware_go_get). Using custom domains, it's possible to arrange things so that a Git repository is cloned to a folder named ".git" by using a vanity import path that ends with "/.git". If the Git repository root contains a "HEAD" file, a "config" file, an "objects" directory, a "refs" directory, with some work to ensure the proper ordering of operations, "go get -u" can be tricked into considering the parent directory as a repository root, and running Git commands on it. That will use the "config" file in the original Git repository root for its configuration, and if that config file contains malicious commands, they will execute on the system running "go get -u".

Specifically, it is only vulnerable in GOPATH mode, but not in module mode (the distinction is documented at https://golang.org/cmd/go/#hdr-Module_aware_go_get). The attacker can cause an arbitrary filesystem write, which can lead to code execution. CVE-2018-16874 SUSE Linux Enterprise Module for Containers 15 SP1:helm-mirror-0.2.1-1.7.1 moderate 6.8 AV:N/AC:M/Au:N/C:P/I:P/A:P To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or "zypper patch". https://www.suse.com/support/update/announcement/2019/suse-su-20190048-2/ https://www.suse.com/security/cve/CVE-2018-16874.html CVE-2018-16874 https://bugzilla.suse.com/1118897 SUSE Bug 1118897 https://bugzilla.suse.com/1118898 SUSE Bug 1118898 https://bugzilla.suse.com/1118899 SUSE Bug 1118899 The crypto/x509 package of Go before 1.10.6 and 1.11.x before 1.11.3 does not limit the amount of work performed for each chain verification, which might allow attackers to craft pathological inputs leading to a CPU denial of service. Go TLS servers accepting client certificates and TLS clients are affected.
