Descriptions
regexp.Compile in Go before 1.16.15 and 1.17.x before 1.17.8 allows stack exhaustion via a deeply nested expression.
El archivo regexp.Compile en Go versiones anteriores a 1.16.15 y versiones 1.17.x anteriores a 1.17.8, permite un agotamiento de la pila por medio de una expresión profundamente anidada
A stack overflow flaw was found in Golang's regexp module, which can crash the runtime if the application using regexp accepts very long or arbitrarily long regexps from untrusted sources that have sufficient nesting depths. To exploit this vulnerability, an attacker would need to send large regexps with deep nesting to the application. Triggering this flaw leads to a crash of the runtime, which causes a denial of service.
