Description

MozillaFirefox was updated to version 2.0.0.16, which fixes various bugs and following security issues :

  • 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 2008-34 / CVE-2008-2785)

  • 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 2008-35 / CVE-2008-2933)
