| summary: Denial of service due to unchecked parameters in crypto/dsa |
| description: |- |
| The Verify function in crypto/dsa passed certain parameters unchecked to the |
| underlying big integer library, possibly leading to extremely long-running |
| computations, which in turn makes Go programs vulnerable to remote denial of |
| service attacks. Programs using HTTPS client certificates or the Go SSH server |
| libraries are both exposed to this vulnerability. |
