CVE-2017-7895 (retired)

Priority
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.
Notes
jdstrandandroid kernels (flo, goldfish, grouper, maguro, mako and manta) are
not supported on the Ubuntu Touch 14.10 and earlier preview kernels
linux-lts-saucy no longer receives official support
linux-lts-quantal no longer receives official support
