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

The fileutils package contains several basic system utilities. One of

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."
