RHEL 2.1 : fileutils (RHSA-2003:310)

Synopsis :

The remote Red Hat host is missing a security update.

Description :

Updated fileutils packages that close a potential denial of service
vulnerability are now available.

The fileutils package contains several basic system utilities. One of
these utilities is the 'ls' program, which is used to list information
about files and directories.

Georgi Guninski discovered a memory starvation denial of service
vulnerability in the ls program. It is possible to make ls allocate a
huge amount of memory by specifying certain command line arguments.
This vulnerability is remotely exploitable through services like
wu-ftpd, which pass user arguments to ls. The Common Vulnerabilities
and Exposures project (cve.mitre.org) has assigned the name
CVE-2003-0854 to this issue.

A non-exploitable integer overflow in ls has been discovered. It is
possible to make ls crash by specifying certain command line
arguments. This vulnerability is remotely exploitable through services
like wu-ftpd, which pass user arguments to ls. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the
name CVE-2003-0853 to this issue.

Users are advised to update to these erratum packages, which contain
backported security patches that correct these vulnerabilities.

These packages also add support for the O_DIRECT flag, which controls
the use of synchronous I/O on file systems such as OCFS.
