RHSA-2005:014 - Security Advisory

Topic

An updated nfs-utils package that fixes various security issues is now
available.

Description

The nfs-utils package provides a daemon for the kernel NFS server and
related tools.

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.

All users of nfs-utils should upgrade to this updated package, which
resolves these issues.
