Go 1.6.1 is in the tree, and should contain the fix [1]. Do we need to do a fast stable for this? If so, go ahead and add arch teams. The targets should be amd64, arm and x86. [1] http://www.openwall.com/lists/oss-security/2016/04/05/1 I spoke with k_f about this bug and he agrees we should fast stable. I will handle amd64 and x86. Arm team, please stable dev-lang/go-1.6.1. @security: What do we want to do with this bug since all affected versions have been removed for a while? CVE-2016-3959 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2016-3959): The Verify function in crypto/dsa/dsa.go in Go before 1.5.4 and 1.6.x before 1.6.1 does not properly check parameters passed to the big integer library, which might allow remote attackers to cause a denial of service (infinite loop) via a crafted public key to a program that uses HTTPS client certificates or SSH server libraries. GLSA Vote: No. |
From ${URL} : Go has an infinite loop in several big integer routines that makes Go programs vulnerable to remote denial of service attacks. Programs using HTTPS client authentication or the Go ssh server libraries are both exposed to this vulnerability. Upstream fix: https://go-review.googlesource.com/#/c/21533/ References: http://seclists.org/oss-sec/2016/q2/11 @maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
