The swiotlb functionality in the r8169 driver in drivers/net/r8169.c in the Linux kernel before 2.6.27.22 allows remote attackers to cause a denial of service (IOMMU space exhaustion and system crash) by using jumbo frames for a large amount of network traffic, as demonstrated by a flood ping. La funcionalidad swiotlb en el controlador r8169 en drivers/net/r8169.c en el núcleo de Linux anterior a v2.6.27.22 permite a atacantes remotos provocar una denegación de servicio (agotamiento de espacio en la Unidad de Gestión de E/S de memoria y parada del sistema) mediante la utilización de una tramas grandes para una gran cantidad de tráfico de red, como se ha demostrado con un desbordamiento ping. • https://www.exploit-db.com/exploits/33289 http://bugzilla.kernel.org/show_bug.cgi?id=9468 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=97d477a914b146e7e6722ded21afa79886ae8ccd http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=a866bbf6aacf95f849810079442a20be118ce905 http://lists.opensuse.org/opensuse-security-announce/2009-12/msg00005.html http://lists.vmware.com/pipermail/security-announce/2010/000082.html http://marc.info/?l=o • CWE-399: Resource Management Errors •
