Descriptions

A buffer overflow vulnerability exists in all versions of sngrep since v0.4.2, due to improper handling of 'Call-ID' and 'X-Call-ID' SIP headers. The functions sip_get_callid and sip_get_xcallid in sip.c use the strncpy function to copy header contents into fixed-size buffers without checking the data length. This flaw allows remote attackers to execute arbitrary code or cause a denial of service (DoS) through specially crafted SIP messages.

Existe una vulnerabilidad de desbordamiento del búfer en todas las versiones de sngrep desde la v0.4.2, debido al manejo inadecuado de los encabezados SIP 'Call-ID' y 'X-Call-ID'. Las funciones sip_get_callid y sip_get_xcallid en sip.c usan la función strncpy para copiar el contenido del encabezado en buffers de tamaño fijo sin verificar la longitud de los datos. Esta falla permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (DoS) a través de mensajes SIP especialmente manipulados.
