Looking at the integrity and accountability of financial reporting
has become headline news. Widely publicized financial scandals have
caused damage to investor, employee, and customer confidence.
Government and regulatory agencies have enacted and are starting to
enforce new regulations for corporate governance to restore
confidence and trust. The response from the United States government
regarding the Enron, WorldCom, and Tyco accounting scandals of the
late 1990's was the Sarbanes-Oxley Act (The Act) of 2002. It
establishes standards for maintaining and preserving electronic
and paper records in addition to the accountability of corporate
executives, employees, and auditors. The Act contains11 titles and
also established new standards for corporate accountability and
penalties of fines and imprisonment. Under the act, companies must
validate financial statements, maintain auditing practices, report
on the effectiveness of the internal controls, and assure integrity
and timeliness of data.
The main purpose of the legislation is to make organizations and
their executives be held responsible for the validity of corporate
reporting. The reporting requires all companies with public
interests to require executives to attest to the accuracy of
the financial conditions and disclosure of internal weaknesses.
An article written by Guardian Digital Inc. says that, "As mandated
by SOX (the Sarbanes-Oxley Act), corporations can accommodate these
regulations through the design, implementation, and maintenance of
efficient and effective internal controls."
There are many sections to the SOA that President Bush signed.
According to Mathew Bender in the book, "The Sarbanes Oxley Act
of 2002 with Analysis", SOA contains two provisions requiring CEOs
and CFOs to certify certain SEC filings. The first section requires
them to certify that annual and quarterly reports have been reviewed
by themselves, does not contain any untrue statement or omit to
state a material fact, information fairly represents the situation,
and they must disclose any deficiencies or changes to the internal
controls. The second section requires that when a report is filed,
the CEO or CFO must have a written statement saying that fully
complies with the requirements and that it fairly represents the
financial and operational results. If they certify the report
knowing that it is false, they can face criminal penalties.

Linux
File & Directory Permissions Mistakes - One common mistake Linux
administrators make is having file and directory permissions that are far
too liberal and allow access beyond that which is needed for proper system
operations. A full explanation of unix file permissions is beyond the scope
of this article, so I'll assume you are familiar with the usage of such
tools as chmod, chown, and chgrp. If you'd like a refresher, one is available
right here on linuxsecurity.com.

Debian
Debian: New OpenOffice.org packages fix
several vulnerabilities
29th, June, 2006
Several vulnerabilities have been discovered in OpenOffice.org,
a free office suite. The Common Vulnerabilities and Exposures Project
identifies the following problems: CVE-2006-2198 CVE-2006-2199 CVE-2006-3117

Debian: New OpenOffice.org packages fix
arbitrary code execution
6th, July, 2006
Loading malformed XML documents can cause buffer overflows in
OpenOffice.org, a free office suite, and cause a denial of service or
execute arbitrary code. It turned out that the correction in DSA 1104-1
was not sufficient, hence, another update.
http://www.linuxsecurity.com/content/view/123458
Multiple buffer overflows in the gd graphics library (libgd)
2.0.21 and earlier may allow remote attackers to execute arbitrary code
via malformed image files that trigger the overflows due to improper calls
to the gdMalloc function. (CVE-2004-0941)
Integer overflows were reported in the GD Graphics Library (libgd)
2.0.28, and possibly other versions. These overflows allow remote attackers
to cause a denial of service and possibly execute arbitrary code via
PNG image files with large image rows values that lead to a heap-based
buffer overflow in the gdImageCreateFromPngCtx() function. Libwmf contains
an embedded copy of the GD library code. (CVE-2004-0990)
Update:
The previous update incorrectly attributed the advisory text to CVE-2004-0941,
while it should have been CVE-2004-0990. Additional review of the code
found fixes for CVE-2004-0941 were missing and have also been included
in this update.
