CVE-2009-1046 Detail
Current Description
The console selection feature in the Linux kernel 2.6.28 before 2.6.28.4, 2.6.25, and possibly earlier versions, when the UTF-8 console is used, allows physically proximate attackers to cause a denial of service (memory corruption) by selecting a small number of 3-byte UTF-8 characters, which triggers an "off-by-two memory error." NOTE: it is not clear whether this issue crosses privilege boundaries.

La funcionalidad de selección de consola en el kernel de Linux 2.6.28 en versiones anteriores a 2.6.28.4, 2.6.25 y posiblemente versiones anteriores, cuando se utiliza la consola UTF-8, permite a atacantes físicamente próximos causar una denegación de servicio (corrupción de memoria) seleccionando un número pequeño de carácteres de 3 bytes UTF-8, lo que desencadena un "error de memoria off-by-two". NOTA: no queda claro si el problema traspasa límites de privilegio. |
