Descriptions

Calling any of the Parse functions on Go source code which contains //line directives with very large line numbers can cause an infinite loop due to integer overflow.

A flaw was found in Golang Go, where it is vulnerable to a denial of service caused by an infinite loop due to integer overflow when calling any of the Parse functions. By sending a specially crafted input, a remote attacker can cause a denial of service.
