Security update for go1.11 SUSE Patch security@suse.de SUSE Security Team openSUSE-SU-2018:4181-1 Final 1 1 2018-12-19T07:11:45Z current 2018-12-19T07:11:45Z 2018-12-19T07:11:45Z cve-database/bin/generate-cvrf.pl 2017-02-24T01:00:00Z Security update for go1.11 This new package for go1.11 fixes the following issues: Security issues fixed: - CVE-2018-16873: Fixed a remote code execution in go get, when executed with the -u flag (bsc#1118897) - CVE-2018-16874: Fixed an arbitrary filesystem write in go get, which could lead to code execution (bsc#1118898) - CVE-2018-16875: Fixed a Denial of Service in the crypto/x509 package during certificate chain validation(bsc#1118899) Non-security issues fixed: - Fixed build error with PIE linker flags on ppc64le (bsc#1113978 bsc#1098017) - Make profile.d/go.sh no longer set GOROOT=, in order to make switching between versions no longer break. This ends up removing the need for go.sh entirely (because GOPATH is also set automatically) (bsc#1119634) The following tracked regression fix is included: - Fix a regression that broke go get for import path patterns containing "..."

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.

Go TLS servers accepting client certificates and TLS clients are affected.
