Title:RHSA-2004:583: nfs-utils security update (Important)
Description: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 CAN-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 CAN-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.
