-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Updated nfs-utils package fixes security vulnerabilities Advisory ID: RHSA-2004:583-01 Advisory URL: https://rhn.redhat.com/errata/RHSA-2004-583.html Issue date: 2004-12-20 Updated on: 2004-12-20 Product: Red Hat Enterprise Linux CVE Names: CAN-2004-1014 CAN-2004-0946 - --------------------------------------------------------------------- 1. Summary: An updated nfs-utils package that fixes various security issues is now available. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Desktop version 3 - i386, x86_64 Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64 3. Problem 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. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: http://www.redhat.com/docs/manuals/enterprise/ 5. Bug IDs fixed (http://bugzilla.redhat.com/): 123900 - LTC5609-Wrong uid/gid for anonuid in nfs mount 139611 - CAN-2004-1014 DoS in statd 138062 - CAN-2004-0946 buffer overflow in rquotad 6.
