Descripción |
|
|
Se ha descubierto una vulnerabilidad en libgadu, una librería que ofrece soporte para el protocolo de mensajería instantánea Gadu Gadu. La vulnerabilidad reside en un error de alineamiento de memoria que puede provocar, bajo determinadas arquitecturas, cómo Sparc, errores de bus. La explotación de esta vulnerabilidad podría permitir a un atacante remoto provocar una situación de denegación de servicio. Gaim es un ejemplo de aplicación que utiliza libgadu y que, por tanto, es vulnerable. |
