nsIRDFService in Mozilla Firefox before 3.0.7, Thunderbird before 2.0.0.21, and SeaMonkey before 1.1.15 allows remote attackers to bypass the same-origin policy and read XML data from another domain via a cross-domain redirect.
Mozilla Firefox before 3.0.7, Thunderbird before 2.0.0.21, and SeaMonkey before 1.1.15 decode invisible characters when they are displayed in the location bar, which causes an incorrect address to be displayed and makes it easier for remote attackers to spoof URLs and conduct phishing attacks.
The Internationalized Domain Names (IDN) blacklist in Mozilla Firefox 3.0.6 and other versions before 3.0.9; Thunderbird before 2.0.0.21; and SeaMonkey before 1.1.15 does not include box-drawing characters, which allows remote attackers to spoof URLs and conduct phishing attacks, as demonstrated by homoglyphs of the / (slash) and ? (question mark) characters in a subdomain of a .cn domain name, a different vulnerability than CVE-2005-0233. NOTE: some third parties claim that 3.0.6 is not affected, but much older versions perhaps are affected.
Multiple unspecified vulnerabilities in Mozilla Firefox 3.x before 3.0.6, Thunderbird before 2.0.0.21, and SeaMonkey before 1.1.15 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to the layout engine and destruction of arbitrary layout objects by the nsViewManager::Composite function.
Unspecified vulnerability in Mozilla Firefox 3.x before 3.0.6, Thunderbird before 2.0.0.21, and SeaMonkey before 1.1.15 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to the JavaScript engine.
Cross-domain vulnerability in js/src/jsobj.cpp in Mozilla Firefox 3.x before 3.0.6 allows remote attackers to bypass the Same Origin Policy, and access the properties of an arbitrary window and conduct cross-site scripting (XSS) attacks, via vectors involving a chrome XBL method and the window.eval function.
components/sessionstore/src/nsSessionStore.js in Mozilla Firefox before 3.0.6 does not block changes of INPUT elements to type="file" during tab restoration, which allows user-assisted remote attackers to read arbitrary files on a client machine via a crafted INPUT element.
Mozilla Firefox before 3.0.6 and SeaMonkey do not block links to the (1) about:plugins and (2) about:config URIs from .desktop files, which allows user-assisted remote attackers to bypass the Same Origin Policy and execute arbitrary code with chrome privileges via vectors involving the URL field in a Desktop Entry section of a .desktop file, related to representation of about: URIs as jar:file:// URIs. NOTE: this issue exists because of an incomplete fix for CVE-2008-4582.
Mozilla Firefox before 3.0.6 and SeaMonkey before 1.1.15 do not properly restrict access from web pages to the (1) Set-Cookie and (2) Set-Cookie2 HTTP response headers, which allows remote attackers to obtain sensitive information from cookies via XMLHttpRequest calls, related to the HTTPOnly protection mechanism.
Mozilla Firefox 3.x before 3.0.6 does not properly implement the (1) no-store and (2) no-cache Cache-Control directives, which allows local users to obtain sensitive information by using the (a) back button or (b) history list of the victim's browser, as demonstrated by reading the response page of an https POST request.
