Descriptions
The NFSv2 and NFSv3 server implementations in the Linux kernel through 4.10.13 lack certain checks for the end of a buffer, which allows remote attackers to trigger pointer-arithmetic errors or possibly have unspecified other impact via crafted requests, related to fs/nfsd/nfs3xdr.c and fs/nfsd/nfsxdr.c.
Las implementaciones de los servidores NFSv2 y NFSv3 en versiones del kernel de Linux 4.10.13 y anteriores, no realizan ciertas comprobaciones de la parte final de un búfer lo que permitiría a atacantes remotos desencadenar errores de aritmética de punteros o provocar otro impacto inespecífico a través de peticiones especialmente diseñadas. Relacionado con fs/nfsd/nfs3xdr.c y fs/nfsd/nfsxdr.c.
