Descriptions
Multiple integer overflows in the evbuffer API in Libevent 1.4.x before 1.4.15, 2.0.x before 2.0.22, and 2.1.x before 2.1.5-beta allow context-dependent attackers to cause a denial of service or possibly have other unspecified impact via "insanely large inputs" to the (1) evbuffer_add, (2) evbuffer_expand, or (3) bufferevent_write function, which triggers a heap-based buffer overflow or an infinite loop. NOTE: this identifier has been SPLIT per ADT3 due to different affected versions. See CVE-2015-6525 for the functions that are only affected in 2.0 and later.
Vulnerabilidad de desbordamientos de entero múltiple en la API evbuffer en Libevent 1.4.x en versiones anteriores a 1.4.15, 2.0.x en versiones anteriores a 2.0.22 y 2.1.x en versiones anteriores a 2.1.5-beta, permite a atacantes dependientes del contexto causar una denegación de servicio o posiblemente tener otro impacto no especificado a través de 'entradas increíblemente grandes' en la función (1) evbuffer_add, (2) evbuffer_expand o (3) bufferevent_write, lo que desencadena un desbordamiento de buffer basado en memoria dinámica o un bucle infinito. NOTA: este identificador ha sido SEPARADO por ADT3 debido a diferentes versiones afectadas. Ver CVE-2015-6525 para las funciones que solo son afectadas en la versión 2.0 y anteriores.
