Descriptions

Uncontrolled recursion in the Parse functions in go/parser before Go 1.17.12 and Go 1.18.4 allow an attacker to cause a panic due to stack exhaustion via deeply nested types or declarations.

Una recursión no controlada en las funciones Parse en go/parser versiones anteriores a Go 1.17.12 y Go 1.18.4, permite a un atacante causar un pánico debido al agotamiento de la pila por medio de tipos o declaraciones profundamente anidados

A flaw was found in the golang standard library, go/parser. When calling any Parse functions on the Go source code, which contains deeply nested types or declarations, a panic can occur due to stack exhaustion. This issue allows an attacker to impact system availability.
