Descriptions

A denial of service vulnerability exists in the handling of the MXIT protocol in Pidgin. Specially crafted MXIT data sent via the server could potentially result in a null pointer dereference. A malicious server or an attacker who intercepts the network traffic can send invalid data to trigger this vulnerability and cause a crash.

Existe una vulnerabilidad de denegación de servicio en el manejo del protocolo MXIT en Pidgin. Datos MXIT especialmente manipulados enviados a través del servidor podrían resultar potencialmente en una referencia a puntero nulo. Un servidor malicioso o un atacante que intercepte el tráfico de red puede enviar datos no válidos para desencadenar esta vulnerabilidad y provocar un bloqueo.

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.
