Mozilla » Firefox » 1.0.1 : Security Vulnerabilities, CVEs,

The Cascading Style Sheets (CSS) implementation in Mozilla Firefox before 4.0, Thunderbird before 3.3, and SeaMonkey before 2.1 does not properly handle the :visited pseudo-class, which allows remote attackers to obtain sensitive information about visited web pages via a crafted HTML document, a related issue to CVE-2010-2264.

The JavaScript implementation in Mozilla Firefox before 4.0, Thunderbird before 3.3, and SeaMonkey before 2.1 does not properly restrict the set of values contained in the object returned by the getComputedStyle method, which allows remote attackers to obtain sensitive information about visited web pages by calling this method.

Heap-based buffer overflow in GIF2.cpp in Firefox before 1.0.2, Mozilla before to 1.7.6, and Thunderbird before 1.0.2, and possibly other applications that use the same library, allows remote attackers to execute arbitrary code via a GIF image with a crafted Netscape extension 2 block and buffer size.

Firefox before 1.0.2 allows remote attackers to execute arbitrary code by tricking a user into saving a page as a Firefox sidebar panel, then using the sidebar panel to inject Javascript into a privileged page.

The Plugin Finder Service (PFS) in Firefox before 1.0.3 allows remote attackers to execute arbitrary code via a javascript: URL in the PLUGINSPAGE attribute of an EMBED tag.

The find_replen function in jsstr.c in the Javascript engine for Mozilla Suite 1.7.6, Firefox 1.0.1 and 1.0.2, and Netscape 7.2 allows remote attackers to read portions of heap memory in a Javascript string via the lambda replace method.

Firefox before 1.0.3 and Mozilla Suite before 1.7.7, when blocking a popup, allows remote attackers to execute arbitrary code via a javascript: URL that is executed when the user selects the "Show javascript" option.

Firefox before 1.0.3 and Mozilla Suite before 1.7.7 allows remote attackers to execute arbitrary script in other domains via a setter function for a variable in the target domain, which is executed when the user visits that domain, aka "Cross-site scripting through global scope pollution."

The favicon functionality in Firefox before 1.0.3 and Mozilla Suite before 1.7.7 allows remote attackers to execute arbitrary code via a <LINK rel="icon"> tag with a javascript: URL in the href attribute, aka "Firelinking."

Firefox before 1.0.3, Mozilla Suite before 1.7.7, and Netscape 7.2 allows remote attackers to execute arbitrary script and code via a new search plugin using sidebar.addSearchEngine, aka "Firesearching 1."

Firefox before 1.0.3, Mozilla Suite before 1.7.7, and Netscape 7.2 allows remote attackers to replace existing search plugins with malicious ones using sidebar.addSearchEngine and the same filename as the target engine, which may not be displayed in the GUI, which could then be used to execute malicious script, aka "Firesearching 2."

Multiple "missing security checks" in Firefox before 1.0.3 allow remote attackers to inject arbitrary Javascript into privileged pages using the _search target of the Firefox sidebar.

The native implementations of InstallTrigger and other functions in Firefox before 1.0.3 and Mozilla Suite before 1.7.7 do not properly verify the types of objects being accessed, which causes the Javascript interpreter to continue execution at the wrong memory address, which may allow attackers to cause a denial of service (application crash) and possibly execute arbitrary code by passing objects of the wrong type.

The privileged "chrome" UI code in Firefox before 1.0.3 and Mozilla Suite before 1.7.7 allows remote attackers to gain privileges by overriding certain properties or methods of DOM nodes, as demonstrated using multiple attacks involving the eval function or the Script object.

Firefox 1.0.3 allows remote attackers to execute arbitrary Javascript in other domains by using an IFRAME and causing the browser to navigate to a previous javascript: URL, which can lead to arbitrary code execution when combined with CVE-2005-1477.

Firefox before 1.0.4 and Mozilla Suite before 1.7.8 does not properly implement certain security checks for script injection, which allows remote attackers to execute script via "Wrapped" javascript: URLs, as demonstrated using (1) a javascript: URL in a view-source: URL, (2) a javascript: URL in a jar: URL, or (3) "a nested variant."

Firefox before 1.0.4 and Mozilla Suite before 1.7.8 do not properly limit privileges of Javascript eval and Script objects in the calling context, which allows remote attackers to conduct unauthorized activities via "non-DOM property overrides," a variant of CVE-2005-1160.

The browser user interface in Firefox before 1.0.5, Mozilla before 1.7.9, and Netscape 8.0.2 and 7.2 does not properly distinguish between user-generated events and untrusted synthetic events, which makes it easier for remote attackers to perform dangerous actions that normally could only be performed manually by the user.

Firefox before 1.0.5, Thunderbird before 1.0.5, Mozilla before 1.7.9, Netscape 8.0.2, and K-Meleon 0.9 runs XBL scripts even when Javascript has been disabled, which makes it easier for remote attackers to bypass such protection.

The InstallTrigger.install method in Firefox before 1.0.5 and Mozilla before 1.7.9 allows remote attackers to execute a callback function in the context of another domain by forcing a page navigation after the install method has been called, which causes the callback to be run in the context of the new page and results in a same origin violation.

Firefox before 1.0.5 allows remote attackers to steal sensitive information by opening a malicious link in the Firefox sidebar using the _search target, then injecting script into other pages via a data: URL.

Firefox before 1.0.5, Mozilla before 1.7.9, and Netscape 8.0.2 and 7.2 allows remote attackers to cause a denial of service (access violation and crash), and possibly execute arbitrary code, by calling InstallVersion.compareTo with an object instead of a string.

Firefox before 1.0.5 and Mozilla before 1.7.9 allows a child frame to call top.focus and other methods in a parent frame, even when the parent is in a different domain, which violates the same origin policy and allows remote attackers to steal sensitive information such as cookies and passwords from web sites whose child frames do not verify that they are in the same domain as their parents.

Firefox before 1.0.5 allows remote attackers to steal information and possibly execute arbitrary code by using standalone applications such as Flash and QuickTime to open a javascript: URL, which is run in the context of the previous page, and may lead to code execution if the standalone application loads a privileged chrome: URL.

Firefox before 1.0.5 and Mozilla before 1.7.9 does not clearly associate a Javascript dialog box with the web page that generated it, which allows remote attackers to spoof a dialog box from a trusted site and facilitates phishing attacks, aka the "Dialog Origin Spoofing Vulnerability."
