Descriptions

Buffer overflow in DNS SRV and NAPTR lookups in Digium Asterisk 15.x before 15.6.2 and 16.x before 16.0.1 allows remote attackers to crash Asterisk via a specially crafted DNS SRV or NAPTR response, because a buffer size is supposed to match an expanded length but actually matches a compressed length.

Desbordamiento de búfer en las búsquedas DNS SRV y NAPTR en Digium Asterisk en versiones 15.x anteriores a la 15.6.2 y versiones 16.x anteriores a la 16.0.1 permite que atacantes remotos provoquen el cierre inesperado de Asterisk mediante una respuesta DNS SRV o NAPTR especialmente manipulada. Esto se debe a que se supone que un tamaño de búfer coincide con una longitud expandida, pero en realidad coincide con una longitud comprimida.
