Mozilla Firefox — свободный браузер на движке Gecko

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.

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."

Firefox before 1.0.1 and Mozilla before 1.7.6 allows remote attackers to spoof the SSL "secure site" lock icon via (1) a web site that does not finish loading, which shows the lock of the previous site, (2) a non-HTTP server that uses SSL, which causes the lock to be displayed when the SSL handshake is completed, or (3) a URL that generates an HTTP 204 error, which updates the icon and location information but does not change the display of the original site.

String handling functions in Mozilla 1.7.3, Firefox 1.0, and Thunderbird before 1.0.2, such as the nsTSubstring_CharT::Replace function, do not properly check the return values of other functions that resize the string, which allows remote attackers to cause a denial of service and possibly execute arbitrary code by forcing an out-of-memory state that causes a reallocation to fail and return a pointer to a fixed address, which leads to heap corruption.

Firefox 1.0 allows remote attackers to execute arbitrary code via plugins that load "privileged content" into frames, as demonstrated using certain XUL events when a user drags a scrollbar two times, aka "Firescrolling."

The Form Fill feature in Firefox before 1.0.1 allows remote attackers to steal potentially sensitive information via an input control that monitors the values that are generated by the autocomplete capability.

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.

Heap-based buffer overflow in the UTF8ToNewUnicode function for Firefox before 1.0.1 and Mozilla before 1.7.6 might allow remote attackers to cause a denial of service (crash) or execute arbitrary code via invalid sequences in a UTF8 encoded string that result in a zero length value.
