Mandriva Linux Security Advisory : firefox (MDVSA-2010:251-2)

high Nessus Plugin ID 51106

Language:

Synopsis

The remote Mandriva Linux host is missing one or more security updates.

Description

Security issues were identified and fixed in firefox :

Security researchers Yosuke Hasegawa and Masatoshi Kimura reported that the x-mac-arabic, x-mac-farsi and x-mac-hebrew character encodings are vulnerable to XSS attacks due to some characters being converted to angle brackets when displayed by the rendering engine.
Sites using these character encodings would thus be potentially vulnerable to script injection attacks if their script filtering code fails to strip out these specific characters (CVE-2010-3770).

Google security researcher Michal Zalewski reported that when a window was opened to a site resulting in a network or certificate error page, the opening site could access the document inside the opened window and inject arbitrary content. An attacker could use this bug to spoof the location bar and trick a user into thinking they were on a different site than they actually were (CVE-2010-3774).

Mozilla security researcher moz_bug_r_a4 reported that the fix for CVE-2010-0179 could be circumvented permitting the execution of arbitrary JavaScript with chrome privileges (CVE-2010-3773).

Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that JavaScript arrays were vulnerable to an integer overflow vulnerability. The report demonstrated that an array could be constructed containing a very large number of items such that when memory was allocated to store the array items, the integer value used to calculate the buffer size would overflow resulting in too small a buffer being allocated. Subsequent use of the array object could then result in data being written past the end of the buffer and causing memory corruption (CVE-2010-3767).

Security researcher regenrecht reported via TippingPoint's Zero Day Initiative that a nsDOMAttribute node can be modified without informing the iterator object responsible for various DOM traversals.
This flaw could lead to a inconsistent state where the iterator points to an object it believes is part of the DOM but actually points to some other object. If such an object had been deleted and its memory reclaimed by the system, then the iterator could be used to call into attacker-controlled memory (CVE-2010-3766).

Security researcher Gregory Fleischer reported that when a Java LiveConnect script was loaded via a data: URL which redirects via a meta refresh, then the resulting plugin object was created with the wrong security principal and thus received elevated privileges such as the abilities to read local files, launch processes, and create network connections (CVE-2010-3775).

Mozilla added the OTS font sanitizing library to prevent downloadable fonts from exposing vulnerabilities in the underlying OS font code.
This library mitigates against several issues independently reported by Red Hat Security Response Team member Marc Schoenefeld and Mozilla security researcher Christoph Diehl (CVE-2010-3768).

Security researcher wushi of team509 reported that when a XUL tree had an HTML \<div\> element nested inside a \<treechildren\> element then code attempting to display content in the XUL tree would incorrectly treat the \<div\> element as a parent node to tree content underneath it resulting in incorrect indexes being calculated for the child content. These incorrect indexes were used in subsequent array operations which resulted in writing data past the end of an allocated buffer. An attacker could use this issue to crash a victim's browser and run arbitrary code on their machine (CVE-2010-3772).

Security researcher echo reported that a web page could open a window with an about:blank location and then inject an \<isindex\> element into that page which upon submission would redirect to a chrome:
document. The effect of this defect was that the original page would wind up with a reference to a chrome-privileged object, the opened window, which could be leveraged for privilege escalation attacks (CVE-2010-3771).

Dirk Heinrich reported that on Windows platforms when document.write() was called with a very long string a buffer overflow was caused in line breaking routines attempting to process the string for display.
Such cases triggered an invalid read past the end of an array causing a crash which an attacker could potentially use to run arbitrary code on a victim's computer (CVE-2010-3769).

Mozilla developers identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products.
Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code (CVE-2010-3776, CVE-2010-3777).

Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more:

Additionally, some packages which require so, have been rebuilt and are being provided as updates.

Update :

A mistake was done with the MDVSA-2010:251 and the MDVSA-2010:251-1 advisories where the localization files for firefox software was NOT updated to the 3.6.13 version. The secteam wishes to apologise for the unfortunate mistake and also wishes everyone a great christmas.

Regards // Santa Claus

Solution
