JSON

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.
