CVE-2002-0830 (CCN-9772)

Assigned:2002-08-05
Published:2002-08-05
Updated:2017-10-10
Summary:Network File System (NFS) in FreeBSD 4.6.1 RELEASE-p7 and earlier, NetBSD 1.5.3 and earlier, and possibly other operating systems, allows remote attackers to cause a denial of service (hang) via an RPC message with a zero length payload, which causes NFS to reference a previous payload and enter an infinite loop.
