Multiple vulnerabilities have been discovered in nfs-utils that could lead to a Denial of Service, or the execution of arbitrary code.
|Package||net-fs/nfs-utils on all architectures|
|Affected versions||< 1.0.6-r6|
|Unaffected versions||>= 1.0.6-r6|
nfs-utils is a package containing the client and daemon implementations for the NFS protocol.
Arjan van de Ven has discovered a buffer overflow on 64-bit architectures in 'rquota_server.c' of nfs-utils (CAN-2004-0946). A remotely exploitable flaw on all architectures also exists in the 'statd.c' file of nfs-utils (CAN-2004-1014), which can be triggered by a mishandled SIGPIPE.
A remote attacker could potentially cause a Denial of Service, or even execute arbitrary code (64-bit architectures only) on a remote NFS server.
There is no known workaround at this time.
All nfs-utils users should upgarde to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=net-fs/nfs-utils-1.0.6-r6"
