Ubuntu 4.10 / 5.04 / 5.10 : mozilla vulnerabilities (USN-275-1)
critical Nessus Plugin ID 21301
Synopsis
The remote Ubuntu host is missing one or more security-related patches.Description
Web pages with extremely long titles caused subsequent launches of Mozilla browser to hang for up to a few minutes, or caused Mozilla to crash on computers with insufficient memory. (CVE-2005-4134)Igor Bukanov discovered that the JavaScript engine did not properly declare some temporary variables. Under some rare circumstances, a malicious website could exploit this to execute arbitrary code with the privileges of the user. (CVE-2006-0292, CVE-2006-1742)
The function XULDocument.persist() did not sufficiently validate the names of attributes. An attacker could exploit this to inject arbitrary XML code into the file 'localstore.rdf', which is read and evaluated at startup. This could include JavaScript commands that would be run with the user's privileges. (CVE-2006-0296)
Due to a flaw in the HTML tag parser a specific sequence of HTML tags caused memory corruption. A malicious website could exploit this to crash the browser or even execute arbitrary code with the user's privileges. (CVE-2006-0748)
An invalid ordering of table-related tags caused Mozilla to use a negative array index. A malicious website could exploit this to execute arbitrary code with the privileges of the user.
(CVE-2006-0749)
Georgi Guninski discovered that embedded XBL scripts of websites could escalate their (normally reduced) privileges to get full privileges of the user if that page is viewed with 'Print Preview'. (CVE-2006-1727)
The crypto.generateCRMFRequest() function had a flaw which could be exploited to run arbitrary code with the user's privileges.
(CVE-2006-1728)
Claus Jorgensen and Jesse Ruderman discovered that a text input box could be pre-filled with a filename and then turned into a file-upload control with the contents intact. A malicious website could exploit this to read any local file the user has read privileges for.
(CVE-2006-1729)
An integer overflow was detected in the handling of the CSS property 'letter-spacing'. A malicious website could exploit this to run arbitrary code with the user's privileges. (CVE-2006-1730)
The methods valueOf.call() and .valueOf.apply() returned an object whose privileges were not properly confined to those of the caller, which made them vulnerable to cross-site scripting attacks. A malicious website could exploit this to modify the contents or steal confidential data (such as passwords) from other opened web pages.
(CVE-2006-1731) The window.controllers array variable (CVE-2006-1732) and event handlers (CVE-2006-1741) were vulnerable to a similar attack.
The privileged built-in XBL bindings were not fully protected from web content and could be accessed by calling valueOf.call() and valueOf.apply() on a method of that binding. A malicious website could exploit this to run arbitrary JavaScript code with the user's privileges. (CVE-2006-1733)
It was possible to use the Object.watch() method to access an internal function object (the 'clone parent'). A malicious website could exploit this to execute arbitrary JavaScript code with the user's privileges. (CVE-2006-1734)
By calling the XBL.method.eval() method in a special way it was possible to create JavaScript functions that would get compiled with the wrong privileges. A malicious website could exploit this to execute arbitrary JavaScript code with the user's privileges.
(CVE-2006-1735)
Michael Krax discovered that by layering a transparent image link to an executable on top of a visible (and presumably desirable) image a malicious site could fool the user to right-click and choose 'Save image as...' from the context menu, which would download the executable instead of the image. (CVE-2006-1736)
Several crashes have been fixed which could be triggered by websites and involve memory corruption. These could potentially be exploited to execute arbitrary code with the user's privileges. (CVE-2006-1737, CVE-2006-1738, CVE-2006-1739, CVE-2006-1790)
If the user has turned on the 'Entering secure site' modal warning dialog, it was possible to spoof the browser's secure-site indicators (the lock icon and the gold URL field background) by first loading the target secure site in a pop-up window, then changing its location to a different site, which retained the displayed secure-browsing indicators from the original site. (CVE-2006-1740).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
