Stack-based buffer overflow in the URL parsing implementation in Mozilla Firefox before 2.0.0.17 and SeaMonkey before 1.1.12 allows remote attackers to execute arbitrary code via a crafted UTF-8 URL in a link.

Mozilla Firefox before 2.0.0.16, and 3.x before 3.0.1, interprets '|' (pipe) characters in a command-line URI as requests to open multiple tabs, which allows remote attackers to access chrome:i URIs, or read arbitrary local files via manipulations involving a series of URIs that is not entirely handled by a vector application, as exploited in conjunction with CVE-2008-2540. NOTE: this issue exists because of an insufficient fix for CVE-2005-2267.

Mozilla 1.9 M8 and earlier, Mozilla Firefox 2 before 2.0.0.15, SeaMonkey 1.1.5 and other versions before 1.1.10, Netscape 9.0, and other Mozilla-based web browsers, when a user accepts an SSL server certificate on the basis of the CN domain name in the DN field, regard the certificate as also accepted for all domain names in subjectAltName:dNSName fields, which makes it easier for remote attackers to trick a user into accepting an invalid certificate for a spoofed web site.

Multiple unspecified vulnerabilities in Mozilla Firefox before 2.0.0.15, Thunderbird 2.0.0.14 and earlier, and SeaMonkey before 1.1.10 allow remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via unknown vectors related to the layout engine.

Multiple unspecified vulnerabilities in Mozilla Firefox before 2.0.0.15, Thunderbird 2.0.0.14 and earlier, and SeaMonkey before 1.1.10 allow remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via unknown vectors related to the JavaScript engine.

Mozilla Firefox before 2.0.0.15 and SeaMonkey before 1.1.10 allow remote attackers to bypass the Same Origin Policy and conduct cross-site scripting (XSS) attacks via vectors involving (1) an event handler attached to an outer window, (2) a SCRIPT element in an unloaded document, or (3) the onreadystatechange handler in conjunction with an XMLHttpRequest.

Mozilla Firefox before 2.0.0.15 and SeaMonkey before 1.1.10 do not properly implement JAR signing, which allows remote attackers to execute arbitrary code via (1) injection of JavaScript into documents within a JAR archive or (2) a JAR archive that uses relative URLs to JavaScript files.

Mozilla Firefox before 2.0.0.15, Thunderbird 2.0.0.14 and earlier, and SeaMonkey before 1.1.10 allow remote attackers to execute arbitrary code via an XUL document that includes a script from a chrome: URI that points to a fastload file, related to this file's "privilege level."

The mozIJSSubScriptLoader.LoadScript function in Mozilla Firefox before 2.0.0.15, Thunderbird 2.0.0.14 and earlier, and SeaMonkey before 1.1.10 does not apply XPCNativeWrappers to scripts loaded from (1) file: URIs, (2) data: URIs, or (3) certain non-canonical chrome: URIs, which allows remote attackers to execute arbitrary code via vectors involving third-party add-ons.

Mozilla Firefox before 2.0.0.15 and SeaMonkey before 1.1.10 allow remote attackers to force the upload of arbitrary local files from a client computer via vectors involving originalTarget and DOM Range.

Mozilla Firefox before 2.0.0.15 and SeaMonkey before 1.1.10 on Mac OS X allow remote attackers to bypass the Same Origin Policy and create arbitrary socket connections via a crafted Java applet, related to the Java Embedding Plugin (JEP) and Java LiveConnect.

Mozilla Firefox before 2.0.0.15 and SeaMonkey before 1.1.10 do not properly handle an invalid .properties file for an add-on, which allows remote attackers to read uninitialized memory, as demonstrated by use of ISO 8859 encoding instead of UTF-8 encoding in a French .properties file.

Mozilla Firefox before 2.0.0.15 and SeaMonkey before 1.1.10 do not properly escape HTML in file:// URLs in directory listings, which allows remote attackers to conduct cross-site scripting (XSS) attacks or have unspecified other impact via a crafted filename.

Mozilla Firefox before 2.0.0.15 and SeaMonkey before 1.1.10 do not properly identify the context of Windows shortcut files, which allows user-assisted remote attackers to bypass the Same Origin Policy via a crafted web site for which the user has previously saved a shortcut.

The block reflow implementation in Mozilla Firefox before 2.0.0.15, Thunderbird 2.0.0.14 and earlier, and SeaMonkey before 1.1.10 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via an image whose display requires more pixels than nscoord_MAX, related to nsBlockFrame::DrainOverflowLines.

Mozilla Firefox before 2.0.0.16 and 3.x before 3.0.1, Thunderbird before 2.0.0.16, and SeaMonkey before 1.1.11 use an incorrect integer data type as a CSS object reference counter in the CSSValue array (aka nsCSSValue:Array) data structure, which allows remote attackers to execute arbitrary code via a large number of references to a common CSS object, leading to a counter overflow and a free of in-use memory, aka ZDI-CAN-349.

Mozilla Firefox 2.0.0.14 allows remote attackers to cause a denial of service (heap corruption and application crash) or possibly execute arbitrary code by triggering an error condition during certain Iframe operations between a JSframe write and a JSframe close, as demonstrated by an error in loading an empty Java applet defined by a 'src="javascript:"' sequence.
