Descriptions
Go before 1.13.15 and 14.x before 1.14.7 can have an infinite read loop in ReadUvarint and ReadVarint in encoding/binary via invalid inputs.
Go versiones anteriores a 1.13.15 y versiones 14.x anteriores a 1.14.7, puede presentar un bucle de lectura infinito en las funciones ReadUvarint y ReadVarint en encoding/binary por medio de entradas no válidas
A flaw was found in the Go encoding/binary package. Certain invalid inputs to the ReadUvarint or the ReadVarint causes those functions to read an unlimited number of bytes from the ByteReader argument before returning an error. This flaw possibly leads to processing more input than expected. The highest threat from this vulnerability is to system availability.
