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.
Mozilla Firefox 3.0.5 allows remote attackers to trick a user into visiting an arbitrary URL via an onclick action that moves a crafted element to the current mouse position, related to a "Status Bar Obfuscation" and "Clickjacking" attack.
The Math.random function in the JavaScript implementation in Mozilla Firefox 3.5.x before 3.5.10 and 3.6.x before 3.6.4, and SeaMonkey before 2.0.5, uses a random number generator that is seeded only once per browser session, which makes it easier for remote attackers to track a user, or trick a user into acting upon a spoofed pop-up message, by calculating the seed value, related to a "temporary footprint" and an "in-session phishing attack."
Mozilla Firefox 3.0.5 and earlier 3.0.x versions, when designMode is enabled, allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a certain (a) replaceChild or (b) removeChild call, followed by a (1) queryCommandValue, (2) queryCommandState, or (3) queryCommandIndeterm call. NOTE: it was later reported that 3.0.6 and 3.0.7 are also affected.
Interaction error in xdg-open allows remote attackers to execute arbitrary code by sending a file with a dangerous MIME type but using a safe type that Firefox sends to xdg-open, which causes xdg-open to process the dangerous file type through automatic type detection, as demonstrated by overwriting the .desktop file.
