Descriptions

A stack-buffer overflow vulnerability exists in all versions of sngrep since v1.4.1. The flaw is due to inadequate bounds checking when copying 'Content-Length' and 'Warning' headers into fixed-size buffers in the sip_validate_packet and sip_parse_extra_headers functions within src/sip.c. This vulnerability allows remote attackers to execute arbitrary code or cause a denial of service (DoS) via crafted SIP messages.

Existe una vulnerabilidad de desbordamiento de búfer en la región stack de la memoria en todas las versiones de sngrep desde la v1.4.1. La falla se debe a una verificación inadecuada de los límites al copiar los encabezados 'Content-Length' y 'Warning' en búferes de tamaño fijo en las funciones sip_validate_packet y sip_parse_extra_headers dentro de src/sip.c. Esta vulnerabilidad permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (DoS) a través de mensajes SIP manipulados.
