Description:
Multiple vulnerabilities have been reported in Mozilla Firefox, which can be exploited by malicious people to bypass certain security restrictions, conduct cross-site scripting and spoofing attacks, gain knowledge of sensitive information, and potentially compromise a user's system.
1) An error in the handling of the "locations.hostname" DOM property can be exploited to bypass certain security restrictions.
For more information:
SA24175
2) An integer underflow error in the Network Security Services (NSS) code when processing SSLv2 server messages can be exploited to cause a heap-based buffer overflow via a certificate with a public key too small to encrypt the "Master Secret".
Successful exploitation may allow execution of arbitrary code.
NOTE: Support for SSLv2 is disabled in Firefox 2.x. This version is only vulnerable if user has modified hidden internal NSS settings to re-enable SSLv2 support.
3) It is possible to conduct cross-site scripting attacks against sites containing a frame with a "data:" URI as source.
Successful exploitation requires that a user is tricked into visiting a malicious website and opening a blocked popup.
4) It is possible to open windows containing local files thereby stealing the contents when the full path of a locally saved file containing malicious script code is known. This can be exploited in combination with a flaw in the seeding of the pseudo-random number generator causing downloaded files to be saved to temporary files with a somewhat predictable name.
Successful exploitation requires that a user is tricked into visiting a malicious website and opening a blocked popup.
5) Browser UI elements like the host name and security indicators can be spoofed using a specially crafted custom cursor and manipulating the CSS3 hotspot property.
6) It may be possible to gain knowledge of sensitive information from a website due to an error resulting in two web pages colliding in the disk cache thereby potentially appending part of one document to the other.
Successful exploitation requires that a user is tricked into visiting a malicious website while visiting the target website.
7) Various errors in the Mozilla parser when handling invalid trailing characters in HTML tag attribute names and during processing of UTF-7 content when child frames inherit the character set of its parent window can be exploited to conduct cross-site scripting attacks.
8) A vulnerability in the Password Manager may be exploited to conduct phishing attacks.
For more information:
SA23046
9) Multiple memory corruption errors exist in the layout engine, JavaScript engine, and in SVG. Some of these may be exploited to execute arbitrary code on a user's system.
10) An error within the handling of the onUnload event handler and self-modifying document.write() calls can be exploited to corrupt memory and potentially execute arbitrary code.
11) The fix for MFSA 2006-72 introduced a regression, which can be exploited to execute arbitrary code by setting the "src" attribute of an "IMG" tag to a specially crafted javascript:URI.
