Descripción |
|
|
Se ha descubierto una vulnerabilidad en bzip2. La vulnerabilidad reside en el proceso de descompresión de archivos bzip2. Bajo determinadas circunstancias éste puede entrar en un bucle infinito, lo que podría resultar en un archivo de salida de tamaño indefinido que consuma todo el espacio disponible en disco. La explotación de esta vulnerabilidad podría permitir a un atacante local provocar una situación de denegación del sistema mediante un archivo bzip2 especialmente diseñado. |
