Security researchers have uncovered "critical" security flaws in a version of the Linux kernel used by a large number of popular distributions.The three bugs allow unauthorized users to read or write to kernel memory locations or to access certain resources in certain servers, according to a SecurityFocus advisory.They could be exploited by malicious, local users to cause denial of service attacks, disclose potentially sensitive information, or gain "root" privileges, according to security experts.The bug affects all versions of the Linux kernel up to version 2.6.24.1, which contains a patch. Distributions such as Ubuntu, Turbolinux, SuSE, Red Hat, Mandriva, Debian and others are affected.The problems are within three functions in the system call fs/splice.c, according to an advisory from Secunia."In the 2.6.23 kernel, the system call functionality has been further extended resulting in ... critical vulnerabilities," said iSEC Security Research in an advisory.Secunia disagreed about the bugs' seriousness, giving them a less critical ranking.Exploit code for the vulnerabilities has been released publicly on the hacker site milw0rm.com, and Core Security Technologies has also developed a commercial exploit for the bugs, researchers said.Researchers advised system administrators to update their kernels immediately.Last month, a U.S. Department of Homeland Security bug-fixing scheme uncovered an average of one security glitch per 1,000 lines of code in 180 widely used open-source software projects.Secunia also previously discovered that the number of security bugs in open-source Red Hat Linux operating system and Firefox browsers, far outstripped comparable products from Microsoft last year.

As per suggestions contained in the FAQ: Herein lies a report of two identified and as-of-yet uncorrected security flaws in Scoop. &nbsp;Enough detail will be provided to assist admins in investigating and correcting the flaws, but it is the author's hope that the details of the flaws will be sufficiently obscured to prevent abuse by the undesirables. Executive summary: Through the exploitation of various unchecked privileged operations, attackers may be able to perform admin-level actions leading to data loss. &nbsp;Additionally, well-intentioned security measures combined with XSS vulnerabilities can be exercised to simulate admin-level action, resulting in data loss.

Mozilla has released a critical security update to Firefox, taking a third shot at patching bugs in the way the browser can be used to launch programs from Web links.The bug, rated &quot;moderate&quot; by Mozilla, lies in the URI (Uniform Resource Identifier) protocol handling technology that is used to launch programs -- an e-mail client for example -- from within the browser. Over the past few months, security researchers have been discovering an increasing number of ways that this technology can be misused, often as a way to install unauthorized software on a victim&#39;s computer.The URI patch is one of eight security bug-fixes that Mozilla has pushed out with the 2.0.0.8 update, released late Thursday.Mozilla developers originally thought that the issue lay within Microsoft&#39;s Internet Explorer software, which could be invoked in a malicious fashion via Firefox. Several days after issuing their first patch, however, they realized that there was a problem with Firefox as well, and rushed out the 2.0.0.6 update.Now, three months after that fix, they&#39;ve patched another URI bug in Firefox that will cut down on the likelihood of programs being launched maliciously through the browser. The 2.0.0.6 release &quot;did not prevent the incorrect file-handling programs from launching which left some risk,&quot; Mozilla said in its advisory . &quot;An additional fix has been applied to Firefox 2.0.0.8 that detects when Windows would mishandle these URIs so that the wrong program does not get launched.&quot;Mozilla developers weren&#39;t certain that this latest twist on the URI problem could really be exploited in Firefox, but they decided to issue this latest URI patch rather than wait to find out for certain, said Window Snyder, Mozilla&#39;s security chief. &quot;We could just say this particular vector is not an issue because we do not have proof,&quot; she said. &quot;We could leave it alone. Rather than spend our time analyzing whether this is a vector that could be vulnerable, we would rather put the block in place and eliminate the possibility. This is a defense-in-depth measure.&quot;Microsoft has said that it plans to patch underlying components in the Windows operating system in an effort to prevent URI protocol handler attacks, and that will probably go a long way in preventing new attacks from cropping up, said Andrew Storms, director of security operations, with nCircle Network Security. &quot;We have to applaud the Mozilla team for attempting to protect their users, but in the end, it&#39;s going to be a Microsoft responsibility,&quot; he said.Of the eight vulnerabilities patched Thursday, two are rated critical by Mozilla.The 2.0.0.8 release also adds support for Apple&#39;s Mac OS X 10.5 operating system, code-named Leopard, although Mozilla warns &quot;there are some known issues affecting some media plugins,&quot; on this platform.
