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.
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.
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 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."
