Descriptions

The Generic Receive Offload (GRO) implementation in the Linux kernel 2.6.18 on Red Hat Enterprise Linux 5 and 2.6.32 on Red Hat Enterprise Linux 6, as used in Red Hat Enterprise Virtualization (RHEV) Hypervisor and other products, allows remote attackers to cause a denial of service via crafted VLAN packets that are processed by the napi_reuse_skb function, leading to (1) a memory leak or (2) memory corruption, a different vulnerability than CVE-2011-1478.

Vulnerabilidad en la implementación de Generic Receive Offload (GRO) en el kernel de Linux versión 2.6.18 en Red Hat Enterprise Linux versiones 5 y 2.6.32 en Red Hat Enterprise Linux versión 6, tal y como se utiliza en el Hypervisor Red Hat Enterprise Virtualization (RHEV) y otros productos, permite a los atacantes remotos generar un denegación de servicio mediante paquetes VLAN creados que son procesados por la función napi_reuse_skb, lo que conduce a (1) una fuga de memoria o (2) daños en la memoria, una vulnerabilidad diferente a CVE-2011-1478.
