Descriptions

drivers/net/r8169.c in the r8169 driver in the Linux kernel 2.6.32.3 and earlier does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to (1) cause a denial of service (temporary network outage) via a packet with a crafted size, in conjunction with certain packets containing A characters and certain packets containing E characters; or (2) cause a denial of service (system crash) via a packet with a crafted size, in conjunction with certain packets containing '\0' characters, related to the value of the status register and erroneous behavior associated with the RxMaxSize register. NOTE: this vulnerability exists because of an incorrect fix for CVE-2009-1389.

drivers/net/r8169.c en el driver r8169 en el kernel de Linux v2.6.32.3 y anteriores no comprueba correctamente el tamaño de una trama Ethernet que excede el tamaño MTU, lo que permite a atacantes remotos (1) producir una denegación de servicio (caída temporal de la red) a través de un paquete con un tamaño manipulado, en unión con ciertos paquetes que contienen caracteres "A" y otros paquetes que contienen caracteres "E"; o (2) producir una denegación de servicio (caída del sistema) a través de un paquete con el tamaño manipulado, junto con algunos paquetes que contienen el carácter '/0', relacionado con el valor del estado de registro y un comportamiento erróneo relacionado con el registro RxMaxSize , NOTA: Esta vulnerabilidad se produjo por un arreglo incorrecto de CVE-20091389.
