The remote Red Hat host is missing a security update.
An updated nfs-utils package that fixes various security issues is now
The nfs-utils package provides a daemon for the kernel NFS server and
related tools, providing a much higher level of performance than the
traditional Linux NFS server used by most users.
This package also contains the showmount program. Showmount queries
the mount daemon on a remote host for information about the NFS
(Network File System) server on the remote host.
SGI reported that the statd daemon did not properly handle the SIGPIPE
signal. A misconfigured or malicious peer could cause statd to crash,
leading to a denial of service. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-1014
to this issue.
Arjan van de Ven discovered a buffer overflow in rquotad. On 64-bit
architectures, an improper integer conversion can lead to a buffer
overflow. An attacker with access to an NFS share could send a
specially crafted request which could lead to the execution of
arbitrary code. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2004-0946 to this issue.
Additionally, this updated package addresses the following issues :
- The UID of the nfsnobody account has been fixed for
32-bit and 64-bit machines. Because the st_uid field of
the stat structure is an unsigned integer, an actual
value of -2 cannot be used when creating the account, so
the decimal value of -2 is used. On a 32-bit machine,
the decimal value of -2 is 65534 but on a 64-bit machine
it is 4294967294. This errata enables the nfs-utils
post-install script to detect the target architecture,
so an appropriate decimal value is used.
All users of nfs-utils should upgrade to this updated package, which
resolves these issues.
