CVE-2017-7895

Priority
Medium
Description
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.
Ubuntu-Description
Tuomas Haanpää and Ari Kauppi discovered that the NFSv2 and NFSv3 server
implementations in the Linux kernel did not properly check for the end of
buffer. A remote attacker could use this to craft requests that cause a
denial of service (system crash) or possibly execute arbitrary code.
