Cross-site scripting (XSS) vulnerability in Mozilla 1.7.12 and possibly earlier, Mozilla Firefox 1.0.7 and possibly earlier, and Netscape 8.1 and possibly earlier, allows remote attackers to inject arbitrary web script or HTML via the -moz-binding (Cascading Style Sheets) CSS property, which does not require that the style sheet have the same origin as the web page, as demonstrated by the compromise of a large number of LiveJournal accounts.

Firefox and Mozilla can associate a cookie with multiple domains when the DNS resolver has a non-root domain in its search list, which allows remote attackers to trick a user into accepting a cookie for a hostname formed via search-list expansion of the hostname entered by the user, or steal a cookie for an expanded hostname, as demonstrated by an attacker who operates an ap1.com Internet web site to steal cookies associated with an ap1.com.example.com intranet web site.

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.

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.

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 1.0.1 and Mozilla before 1.7.6 do not sufficiently address all attack vectors for loading chrome files and hijacking drag and drop events, which allows remote attackers to execute arbitrary XUL code by tricking a user into dragging a scrollbar, a variant of CVE-2005-0527, aka "Firescrolling 2."

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.

The installation confirmation dialog in Firefox before 1.0.1, Thunderbird before 1.0.1, and Mozilla before 1.7.6 allows remote attackers to use InstallTrigger to spoof the hostname of the host performing the installation via a long "user:pass" sequence in the URL, which appears before the real hostname.

Firefox before 1.0.1 and Mozilla before 1.7.6 does not restrict xsl:include and xsl:import tags in XSLT stylesheets to the current domain, which allows remote attackers to determine the existence of files on the local system.

Firefox before 1.0.1 and Mozilla before 1.7.6 allows remote malicious web sites to overwrite arbitrary files by tricking the user into downloading a .LNK (link) file twice, which overwrites the file that was referenced in the first .LNK file.

Thunderbird 0.6 through 0.9 and Mozilla 1.7 through 1.7.3 does not obey the network.cookie.disableCookieForMailNews preference, which could allow remote attackers to bypass the user's intended privacy and security policy by using cookies in e-mail messages.

Heap-based buffer overflow in MSGUnEscapeSearchUrl in nsNNTPProtocol.cpp for Mozilla 1.7.3 and earlier allows remote attackers to cause a denial of service (application crash) via an NNTP URL (news:) with a trailing '\' (backslash) character, which prevents a string from being NULL terminated.

Mozilla before 1.7.6, and Firefox before 1.0.1, allows remote attackers to spoof arbitrary web sites by injecting content from one window into a target window whose name is known but resides in a different domain, as demonstrated using a pop-up window on a trusted web site, aka the "window injection" vulnerability.

Firefox before 1.0 and Mozilla before 1.7.5 allows inactive (background) tabs to launch dialog boxes, which can allow remote attackers to spoof the dialog boxes from web sites in other windows and facilitate phishing attacks, aka the "Dialog Box Spoofing Vulnerability."

Firefox before 1.0 and Mozilla before 1.7.5 allow inactive (background) tabs to focus on input being entered in the active tab, as originally reported using form fields, which allows remote attackers to steal sensitive data that is intended for other sites, which could facilitate phishing attacks.

Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 may allow remote attackers to trick users into performing unexpected actions, including installing software, via signed scripts that request enhanced abilities using the enablePrivilege parameter, then modify the meaning of certain security-relevant dialog messages.

The XPInstall installer in Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 sets insecure permissions for certain installed files within xpi packages, which could allow local users to overwrite arbitrary files or execute arbitrary code.

Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 allows untrusted Javascript code to read and write to the clipboard, and possibly obtain sensitive information, via script-generated events such as Ctrl-Ins.

The Linux install .tar.gz archives for Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8, create certain files with insecure permissions, which could allow local users to overwrite those files and execute arbitrary code.
