Descriptions
The XMPP protocol plugin in libpurple in Pidgin before 2.10.1 does not properly handle missing fields in (1) voice-chat and (2) video-chat stanzas, which allows remote attackers to cause a denial of service (application crash) via a crafted message.
El complemento del protocolo XMPP de libpurple de Pidgin en versiones anteriores a 2.10.1 no maneja apropiadamente campos faltantes en párrafos (1) voice-chat y (2) video-chat, lo que permite a atacantes remotos provocar una denegación de servicio (caída de la aplicación) a través de un mensaje modificado.
