Descriptions

A buffer overflow vulnerability exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent from the server could potentially result in arbitrary code execution. A malicious server or an attacker who intercepts the network traffic can send an invalid size for a packet which will trigger a buffer overflow.

Existe una vulnerabilidad de desbordamiento de búfer en el manejo del protocolo MXIT en Pidgin. Datos MXIT especialmente manipulados enviados desde el servidor podrían resultar potencialmente en ejecución de código arbitrario. Un servidor malicioso o un atacante que intercepte el tráfico red puede enviar un tamaño inválido para un paquete que desencadenará un desbordamiento de búfer.

Yves Younan of Cisco Talos discovered several vulnerabilities in the MXit protocol support in pidgin, a multi-protocol instant messaging client. A remote attacker can take advantage of these flaws to cause a denial of service (application crash), overwrite files, information disclosure, or potentially to execute arbitrary code.
