Descriptions

libpurple in Pidgin before 2.7.4 does not properly validate the return value of the purple_base64_decode function, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and application crash) via a crafted message, related to the plugins for MSN, MySpaceIM, XMPP, and Yahoo! and the NTLM authentication support.

libpurple en Pidgin anterior a v2.7.4 no valida correctamente el valor de retorno de la función purple_base64_decode, lo cual permite a usuarios remotos autenticados causar una denegación de servicio (desreferencia de puntero nulo y cuelgue de la aplicación) a través de un mensaje hecho a mano, relacionado con los plugins para el MSN, MySpaceIM, XMPP y Yahoo y con el soporte de autenticación NTLM.
