Less critical

Noam Rathaus has discovered a vulnerability in KMail, which can be exploited by malicious people to conduct spoofing attacks.

The vulnerability is caused due to an error where HTML code can overlay part of the user interface. This can e.g. be exploited to trick a user into believing a specially crafted mail is signed and coming from a trusted source.

Successful exploitation requires that the option "Prefer HTML to plain text" is enabled (not default setting).

The vulnerability has been confirmed in KMail 1.7.1 on KDE 3.3.1. KDE 3.3.2 is reportedly also affected. Other versions may also be affected.

Solution:

Disable the "Prefer HTML to plain text" setting. Link.

Serious
Red Hat Inc. is warning enterprise Linux users to update their installations of XFree86 to fix a number of serious security bugs, some of which could allow attackers to take over a system. Affected operating systems include Enterprise Linux AS 3, Enterprise Linux ES 3 and Enterprise Linux WS 3, Red Hat said in an advisory. XFree86 is an implementation of the X Window System that provides low-level graphics functionality for graphical user interface systems such as KDE and Gnome. The most serious flaw is an integer overflow in the libXpm library, used by some applications in opening XPixMap images, Red Hat said. An attacker could use a malicious XPixMap file to execute code on a user's system. Source for this one.

Open Source Software A Core Competency For Effective Tech M&A

Imagine your company just acquired its competitor for $100 million. Now imagine the company’s most important asset – its proprietary software – is subject to third-party license conditions that require the proprietary software to be distributed free of charge or in source code form. Or, imagine these license conditions are discovered late in the diligence process, and the cost to replace the offending third-party software will costs tens of thousands of dollars and take months to remediate. Both scenarios exemplify the acute, distinct and often overlooked risks inherent to the commercial use of open source software. An effective tech M&A attorney must appreciate these risks and be prepared to take the steps necessary to mitigate or eliminate them. Over the past decade, open source software has become a mainstay in the technology community. Since its beginnings, open source software has always been viewed as a way to save money and jumpstart development projects, but it is increasingly being looked to for its quality solutions and operational advantages. Today, only a fraction of technology companies do not use open source software in any way. For most of the rest, it is mission critical. Read more
