SuSE 10 Security Update : Mozilla Firefox (ZYPP Patch Number 6606)

Critical Nessus Plugin ID 42365


The remote SuSE 10 host is missing a security-related patch.


The Mozilla Firefox browser was updated to version 3.5.4 to fix various bugs and security issues.

The following security issues have been fixed :

- Security researcher Paul Stone reported that a user's form history, both from web content as well as the smart location bar, was vulnerable to theft. A malicious web page could synthesize events such as mouse focus and key presses on behalf of the victim and trick the browser into auto-filling the form fields with history entries and then reading the entries. (MFSA 2009-52 / CVE-2009-3370)

- Security researcher Jeremy Brown reported that the file naming scheme used for downloading a file which already exists in the downloads folder is predictable. If an attacker had local access to a victim's computer and knew the name of a file the victim intended to open through the Download Manager, he could use this vulnerability to place a malicious file in the world-writable directory used to save temporary downloaded files and cause the browser to choose the incorrect file when opening it. Since this attack requires local access to the victim's machine, the severity of this vulnerability was determined to be low.
(MFSA 2009-53 / CVE-2009-3274)

- Security researcher Orlando Berrera of Sec Theory reported that recursive creation of JavaScript web-workers can be used to create a set of objects whose memory could be freed prior to their use. These conditions often result in a crash which could potentially be used by an attacker to run arbitrary code on a victim's computer. (MFSA 2009-54 / CVE-2009-3371)

- Security researcher Marco C. reported a flaw in the parsing of regular expressions used in Proxy Auto-configuration (PAC) files. In certain cases this flaw could be used by an attacker to crash a victim's browser and run arbitrary code on their computer. Since this vulnerability requires the victim to have PAC configured in their environment with specific regular expresssions which can trigger the crash, the severity of the issue was determined to be moderate. (MFSA 2009-55 / CVE-2009-3372)

- Security research firm iDefense reported that researcher regenrecht discovered a heap-based buffer overflow in Mozilla's GIF image parser. This vulnerability could potentially be used by an attacker to crash a victim's browser and run arbitrary code on their computer. (MFSA 2009-56 / CVE-2009-3373)

- Mozilla security researcher moz_bug_r_a4 reported that the XPCOM utility XPCVariant::VariantDataToJS unwrapped doubly-wrapped objects before returning them to chrome callers. This could result in chrome privileged code calling methods on an object which had previously been created or modified by web content, potentially executing malicious JavaScript code with chrome privileges. (MFSA 2009-57 / CVE-2009-3374)

- Security researcher Alin Rad Pop of Secunia Research reported a heap-based buffer overflow in Mozilla's string to floating point number conversion routines.
Using this vulnerability an attacker could craft some malicious JavaScript code containing a very long string to be converted to a floating point number which would result in improper memory allocation and the execution of an arbitrary memory location. This vulnerability could thus be leveraged by the attacker to run arbitrary code on a victim's computer. (MFSA 2009-59 / CVE-2009-1563)

- Security researcher Gregory Fleischer reported that text within a selection on a web page can be read by JavaScript in a different domain using the document.getSelection function, violating the same-origin policy. Since this vulnerability requires user interaction to exploit, its severity was determined to be moderate. (MFSA 2009-61 / CVE-2009-3375)

- Mozilla security researchers Jesse Ruderman and Sid Stamm reported that when downloading a file containing a right-to-left override character (RTL) in the filename, the name displayed in the dialog title bar conflicts with the name of the file shown in the dialog body. An attacker could use this vulnerability to obfuscate the name and file extension of a file to be downloaded and opened, potentially causing a user to run an executable file when they expected to open a non-executable file.
(MFSA 2009-62 / CVE-2009-3376)

- Mozilla upgraded several thirdparty libraries used in media rendering to address multiple memory safety and stability bugs identified by members of the Mozilla community. Some of the bugs discovered could potentially be used by an attacker to crash a victim's browser and execute arbitrary code on their computer. liboggz, libvorbis, and liboggplay were all upgraded to address these issues. Audio and video capabilities were added in Firefox 3.5 so prior releases of Firefox were not affected. Georgi Guninski reported a crash in liboggz.
(CVE-2009-3377), Lucas Adamski, Matthew Gregan, David Keeler, and Dan Kaminsky reported crashes in libvorbis.
(CVE-2009-3379), Juan Becerra reported a crash in liboggplay. (CVE-2009-3378). (MFSA 2009-63 / CVE-2009-3377 / CVE-2009-3379 / CVE-2009-3378)

- Mozilla developers and community members identified and fixed several stability bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these crashes 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. (MFSA 2009-64 / CVE-2009-3380 / CVE-2009-3381 / CVE-2009-3382 / CVE-2009-3383)
