Descriptions

There is a stack-based buffer underflow in the third instance of the calculate_gain function in libfaad/sbr_hfadj.c in Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.8. A crafted input will lead to a denial of service or possibly unspecified other impact because limiting the additional noise energy level is mishandled for the G_max <= G case.

Hay un subdesbordamiento de búfer basado en pila en la tercera instancia de la función calculate_gain en libfaad/sbr_hfadj.c en Freeware Advanced Audio Decoder 2 (FAAD2) 2.8.8. Una entrada manipulada conducirá a una denegación de servicio (DoS) o, posiblemente, otro tipo de impacto sin especificar. Esto se debe a que el nivel de energía adicional de ruido se gestiona de manera incorrecta para el caso G_max <= G.

Multiple vulnerabilities have been discovered in faad2, the Freeware Advanced Audio Coder. These vulnerabilities might allow remote attackers to cause denial-of-service, or potentially execute arbitrary code if crafted MPEG AAC files are processed.
