It includes fixes to the following security problems:
- CVE-2006-3113/MFSA 2006-46: Memory corruption with simultaneous events Secunia Research has discovered a vulnerability in Mozilla Firefox 1.5 branch, which can be exploited by malicious people to compromise a user's system. The vulnerability is caused due to an memory corruption error within the handling of simultaneously happening XPCOM events, which leads to use of a deleted timer object. This generally results in a crash but potentially could be exploited to execute arbitrary code on a user's system when a malicious website is visited.
- CVE-2006-3802/MFSA 2006-47: Native DOM methods can be hijacked across domains A malicious page can hijack native DOM methods on a document object in another domain, which will run the attacker's script when called by the victim page. This could be used to steal login cookies, password, or other sensitive data on the target page, or to perform actions on behalf of a logged-in user. Access checks on all other properties and document nodes are performed correctly. This cross-site scripting (XSS) attack is limited to pages which use standard DOM methods of the top-level document object, such as document.getElementById(). This includes many popular sites, especially the newer ones that offer rich interaction to the user.
- CVE-2006-3804/MFSA 2006-49: Heap buffer overwrite on malformed VCard A VCard attachment with a malformed base64 field (such as a photo) can trigger a heap buffer overwrite. These have proven exploitable in the past, though in this case the overwrite is accompanied by an integer underflow that would attempt to copy more data than the typical machine has, leading to a crash.
- CVE-2006-3808/MFSA 2006-52: PAC privilege escalation using Function.prototype.call moz_bug_r_a4 reports that a malicious Proxy AutoConfig (PAC) server could serve a PAC script that can execute code with elevated privileges by setting the required FindProxyForURL function to the eval method on a privileged object that leaked into the PAC sandbox. By redirecting the victim to a specially-crafted URL -- easily done since the PAC script controls which proxy to use -- the URL "hostname" can be executed as privileged script. A malicious proxy server can perform spoofing attacks on the user so it was already important to use a trustworthy PAC server.
- CVE-2006-3809/MFSA 2006-53: UniversalBrowserRead privilege escalation shutdown reports that scripts granted the UniversalBrowserRead privilege can leverage that into the equivalent of the far more powerful UniversalXPConnect since they are allowed to "read" into a privileged context. This allows the attacker the ability to run scripts with the full privelege of the user running the browser, possibly installing malware or snooping on private data. This has been fixed so that UniversalBrowserRead and UniversalBrowserWrite are limited to reading from and writing into only normally-privileged browser windows and frames.
- CVE-2006-3810/MFSA 2006-54: XSS with XPCNativeWrapper(window).Function(...) shutdown reports that cross-site scripting (XSS) attacks could be performed using the construct XPCNativeWrapper(window).Function(...), which created a function that appeared to belong to the window in question even after it had been navigated to the target site.
- CVE-2006-3811/MFSA 2006-55: Crashes with evidence of memory corruption As part of the Firefox 184.108.40.206 stability and security release, developers in the Mozilla community looked for and fixed several crash bugs to improve the stability of Mozilla clients. Some of these crashes showed evidence of memory corruption that we presume could be exploited to run arbitrary code with enough effort.
- CVE-2006-3812/MFSA 2006-56: chrome: scheme loading remote content Benjamin Smedberg discovered that chrome URL's could be made to reference remote files, which would run scripts with full privilege. There is no known way for web content to successfully load a chrome: url, but if a user could be convinced to do so manually (perhaps by copying a link and pasting it into the location bar) this could be exploited.
