Linux kernel 2.4.22 - 2.4.25 Linux kernel 2.6.1- 2.6.3 |
Descripción |
|
|
Se ha descubierto una vulnerabilidad de desbordamiento de entero en las versiones de la 2.4.22 a la 2.4.25 y de la 2.6.1 a la 2.6.3 del kernel de Linux. La vulnerabilidad reside en la función ip_setsockopt(), una subrutina de la llamada al sistema setsockopt. Esta llamada al sistema permite la manipulación de varias opciones de un socket IP, el código vulnerable se encuentra concretamente en el manejo de la opción MCAST_MSFILTER. La explotación de esta vulnerabilidad podría permitir a un atacante local conseguir privilegios de root. |
