security flaw

Netscape 6.2.3 and earlier, and Mozilla 1.0.1, allow remote attackers to corrupt heap memory and execute arbitrary code via a GIF image with a zero width.

Mozilla Firefox 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 allows remote attackers to trick users into downloading and saving an executable file via an image that is overlaid by a transparent image link that points to the executable, which causes the executable to be saved when the user clicks the "Save image as..." option. NOTE: this attack is made easier due to a GUI truncation issue that prevents the user from seeing the malicious extension when there is extra whitespace in the filename.

Firefox before 1.0 does not properly distinguish between user-generated and synthetic click events, which allows remote attackers to use Javascript to bypass the file download prompt when the user uses the Alt-click feature.

security flaw

The JavaScript engine in Mozilla Firefox and Thunderbird 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 does not properly handle temporary variables that are not garbage collected, which might allow remote attackers to trigger operations on freed memory and cause memory corruption.

security flaw

Mozilla Firefox and Thunderbird 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 allows remote attackers to execute arbitrary code by using an eval in an XBL method binding (XBL.method.eval) to create Javascript functions that are compiled with extra privileges.

security flaw

Firefox before 1.0 and Mozilla before 1.7.5 display the secure site lock icon when a view-source: URL references a secure SSL site while an insecure page is being loaded, which could facilitate phishing attacks.

security flaw

Mozilla Firefox and Thunderbird 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 allows remote attackers to execute arbitrary code by using the Object.watch method to access the "clone parent" internal function.

describecomponents.cgi in Bugzilla 2.17.3 and 2.17.4 does not properly verify group membership when bug entry groups are used, which allows remote attackers to list component descriptions for otherwise restricted products.

security flaw

Mozilla Firefox and Thunderbird 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 does not properly protect the compilation scope of privileged built-in XBL bindings, which allows remote attackers to execute arbitrary code via the (1) valueOf.call or (2) valueOf.apply methods of an XBL binding, or (3) "by inserting an XBL method into the DOM's document.body prototype chain."

security flaw

Firefox before 1.0 and Mozilla before 1.7.5 display the SSL lock icon when an insecure page loads a binary file from a trusted site, which could facilitate phishing attacks.

security flaw

Unspecified vulnerability in Mozilla Firefox and Thunderbird 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 allows remote attackers to bypass same-origin protections and conduct cross-site scripting (XSS) attacks via unspecified vectors involving the window.controllers array.

security flaw

Mozilla Firefox and Thunderbird 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 returns the Object class prototype instead of the global window object when (1) .valueOf.call or (2) .valueOf.apply are called without any arguments, which allows remote attackers to conduct cross-site scripting (XSS) attacks.

security flaw

Firefox 0.9, Thunderbird 0.6 and other versions before 0.9, and Mozilla 1.7 before 1.7.5 save temporary files with world-readable permissions, which allows local users to read certain web content or attachments that belong to other users, e.g. content that is managed by helper applications such as PDF.

security flaw

Integer overflow in Mozilla Firefox and Thunderbird 1.x before 1.5.0.2 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0.1 allows remote attackers to execute arbitrary code via a large number in the CSS letter-spacing property that leads to a heap-based buffer overflow.

votes.cgi in Bugzilla 2.16.3 and earlier, and 2.17.1 through 2.17.4, allows remote attackers to read a user's voting page when that user has voted on a restricted bug, which allows remote attackers to read potentially sensitive voting information by modifying the who parameter.

The Javascript "Same Origin Policy" (SOP), as implemented in (1) Netscape, (2) Mozilla, and (3) Internet Explorer, allows a remote web server to access HTTP and SOAP/XML content from restricted sites by mapping the malicious server's parent DNS domain name to the restricted site, loading a page from the restricted site into one frame, and passing the information to the attacker-controlled frame, which is allowed because the document.domain of the two frames matches on the parent domain.

security flaw

Mozilla Firefox 1.x before 1.5.0.2 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0.1 allows remote attackers to read arbitrary files by (1) inserting the target filename into a text box, then turning that box into a file upload control, or (2) changing the type of the input control that is associated with an event handler.

security flaw

Firefox before 1.0 and Mozilla before 1.7.5 allow remote attackers to load local files via links "with a custom getter and toString method" that are middle-clicked by the user to be opened in a new tab.

security flaw

show_bug.cgi in Bugzilla before 2.14.1 allows a user with "Bugs Access" privileges to see other products that are not accessible to the user, by submitting a bug and reading the resulting Product pulldown menu.

security flaw

Unspecified vulnerability in Mozilla Firefox and Thunderbird 1.x before 1.5.0.2 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0.1 allows remote attackers to execute arbitrary code via unknown vectors related to the crypto.generateCRMFRequest method.
