openSUSE Security Update : MozillaFirefox (MozillaFirefox-125)
High Nessus Plugin ID 39882
SynopsisThe remote openSUSE host is missing a security update.
DescriptionThis update brings Mozilla Firefox to version 3.0.1. It fixes various bugs and also following security problems :
MFSA 2008-34 / CVE-2008-2785: An anonymous researcher, via TippingPoint's Zero Day Initiative program, reported a vulnerability in Mozilla CSS reference counting code. The vulnerability was caused by an insufficiently sized variable being used as a reference counter for CSS objects. By creating a very large number of references to a common CSS object, this counter could be overflowed which could cause a crash when the browser attempts to free the CSS object while still in use. An attacker could use this crash to run arbitrary code on the victim's computer
MFSA 2008-35 / CVE-2008-2933: Security researcher Billy Rios reported that if Firefox is not already running, passing it a command-line URI with pipe symbols will open multiple tabs. This URI splitting could be used to launch privileged chrome: URIs from the command-line, a partial bypass of the fix for MFSA 2005-53 which blocks external applications from loading such URIs.
This vulnerability could also be used by an attacker to launch a file:
URI from the command line opening a malicious local file which could exfiltrate data from the local filesystem.
Combined with a vulnerability which allows an attacker to inject code into a chrome document, the above issue could be used to run arbitrary code on a victim's computer. Such a chrome injection vulnerability was reported by Mozilla developers Ben Turner and Dan Veditz who showed that a XUL based SSL error page was not properly sanitizing inputs and could be used to run arbitrary code with chrome privileges.
MFSA 2008-36 / CVE-2008-2934: Apple Security Researcher Drew Yao reported a vulnerability in Mozilla graphics code which handles GIF rendering in Mac OS X. He demonstrated that a GIF file could be specially crafted to cause the browser to free an uninitialized pointer. An attacker could use this vulnerability to crash the browser and potentially execute arbitrary code on the victim's computer.
SolutionUpdate the affected MozillaFirefox packages.
