Arch Linux Security Advisory ASA-201812-12 ========================================== Severity: High Date : 2018-12-18 CVE-ID : CVE-2018-16873 CVE-2018-16874 CVE-2018-16875 Package : go-pie Type : multiple issues Remote : Yes Link : https://security.archlinux.org/AVG-835 Summary ======= The package go-pie before version 2:1.11.3-1 is vulnerable to multiple issues including arbitrary command execution, directory traversal and denial of service. Resolution ========== Upgrade to 2:1.11.3-1. # pacman -Syu "go-pie>=2:1.11.3-1" The problems have been fixed upstream in version 1.11.3. Workaround ========== None. Description =========== - CVE-2018-16873 (arbitrary command execution) In Go before 1.10.6 and 1.11.x before 1.11.3, 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, or a package that imports it directly or indirectly. 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". - CVE-2018-16874 (directory traversal) In Go before 1.10.6 and 1.11.x before 1.11.3, 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). 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-2018-16875 (denial of service) 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. Impact ====== A remote attacker can execute arbitrary code or perform a denial of service attack.
