CVE-2017-7645 [HIGH] CWE-130 kernel: nfsd: Incorrect handling of long RPC replies
kernel: nfsd: Incorrect handling of long RPC replies
The NFSv2/NFSv3 server in the nfsd subsystem in the Linux kernel through 4.10.11 allows remote attackers to cause a denial of service (system crash) via a long RPC reply, related to net/sunrpc/svc.c, fs/nfsd/nfs3xdr.c, and fs/nfsd/nfsxdr.c.
The NFS2/3 RPC client could send long arguments to the NFS server. These encoded arguments are stored in an array of memory pages, and accessed using pointer variables. Arbitrarily long arguments could make these pointers point outside the array and cause an out-of-bounds memory access. A remote user or program could use this flaw to crash the kernel, resulting in denial of service.

CVE-2017-7645 [HIGH] CVE-2017-7645 kernel: nfsd: Incorrect handling of long RPC replies
CVE-2017-7645 kernel: nfsd: Incorrect handling of long RPC replies
The Linux kernel built with the NFS Server Support(CONFIG_NFSD) is vulnerable to an out-of-bounds memory access issue. It could occur while processing arbitrarily long arguments sent by the NFSv2/NFSv3 PRC clients.
A remote RPC user/program could use this flaw to crash the krenel, resulting in DoS.
