NVD Description
Note: Versions mentioned in the description apply only to the upstream golang-src package and not the golang-src package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
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.
