Descripción |
|
|
Se han descubierto múltiples vulnerabilidades en Linux kernel 2.6. Las vulnerabilidades son descritas a continuación: - CVE-2008-3831: La vulnerabilidad reside en un error en "drivers/char/drm/i915_dma.c" y en "sys/dev/pci/drm/i915_drv.c". Un atacante local podría causar una denegación de servicio mediante una llamada ioctl especialmente diseñada relacionada con los flags "DRM_MASTER" y "DRM_ROOT_ONLY" en la configuración ioctl. - CVE-2008-4445: La vulnerabilidad reside en un error en la implementación del protocolo SCTP en la función "sctp_auth_ep_set_hmacs" en el fichero "net/sctp/auth.c" cuando la extensión "SCTP-AUTH" está activada, la cual no verifica correctamente los límites del índice del identificador establecidos por "SCTP_AUTH_HMAC_ID_MAX". Un atacante local podría acceder a información privilegiada mediante una consulta "SCTP_HMAC_IDENT IOCTL" especialmente diseñada empleando la función "sctp_getsockopt". |
