CVE-2005-1476

CVE-2011-1179
The SPICE Firefox plug-in (spice-xpi) 2.4, 2.3, 2.2, and possibly other versions allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to (1) plugin/nsScriptablePeer.cpp and (2) plugin/plugin.cpp, which trigger multiple uses of an uninitialized pointer.

CVE-2010-0179
Mozilla Firefox before 3.0.19 and 3.5.x before 3.5.8, and SeaMonkey before 2.0.3, when the XMLHttpRequestSpy module in the Firebug add-on is used, does not properly handle interaction between the XMLHttpRequestSpy object and chrome privileged objects, which allows remote attackers to execute arbitrary JavaScript via a crafted HTTP response.

CVE-2009-0356
Mozilla Firefox before 3.0.6 and SeaMonkey do not block links to the (1) about:plugins and (2) about:config URIs from .desktop files, which allows user-assisted remote attackers to bypass the Same Origin Policy and execute arbitrary code with chrome privileges via vectors involving the URL field in a Desktop Entry section of a .desktop file, related to representation of about: URIs as jar:file:// URIs. NOTE: this issue exists because of an incomplete fix for CVE-2008-4582.

CVE-2015-4507
The SavedStacks class in the JavaScript implementation in Mozilla Firefox before 41.0, when the Debugger API is enabled, allows remote attackers to cause a denial of service (getSlotRef assertion failure and application exit) or possibly execute arbitrary code via a crafted web site.

5.1EPSS 0.032
CVE-2008-5015
Mozilla Firefox 3.x before 3.0.4 assigns chrome privileges to a file: URI when it is accessed in the same tab from a chrome or privileged about: page, which makes it easier for user-assisted attackers to execute arbitrary JavaScript with chrome privileges via malicious code in a file that has already been saved on the local system.

5.1EPSS 0.022
CVE-2006-2784
The PLUGINSPAGE functionality in Mozilla Firefox before 1.5.0.4 allows remote user-assisted attackers to execute privileged code by tricking a user into installing missing plugins and selecting the "Manual Install" button, then using nested javascript: URLs. NOTE: the manual install button is used for downloading software from a remote web site, so this issue would not cross privilege boundaries if the user progresses to the point of installing malicious software from the attacker-controlled site.

CVE-2015-0802
Mozilla Firefox before 37.0 relies on docshell type information instead of page principal information for Window.webidl access control, which might allow remote attackers to execute arbitrary JavaScript code with chrome privileges via certain content navigation that leverages the reachability of a privileged window with an unintended persistence of access to restricted internal methods.

CVE-2015-0816
Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6, and Thunderbird before 31.6 do not properly restrict resource: URLs, which makes it easier for remote attackers to execute arbitrary JavaScript code with chrome privileges by leveraging the ability to bypass the Same Origin Policy, as demonstrated by the resource: URL associated with PDF.js.

5.01 PoCEPSS 0.669
CVE-2005-4134
Mozilla Firefox 1.5, Netscape 8.0.4 and 7.2, and K-Meleon before 0.9.12 allows remote attackers to cause a denial of service (CPU consumption and delayed application startup) via a web site with a large title, which is recorded in history.dat but not processed efficiently during startup. NOTE: despite initial reports, the Mozilla vendor does not believe that this issue can be used to trigger a crash or buffer overflow in Firefox. Also, it has been independently reported that Netscape 8.1 does not have this issue.

5.01 PoCEPSS 0.126
CVE-2013-6629
The get_sos function in jdmarker.c in (1) libjpeg 6b and (2) libjpeg-turbo through 1.3.0, as used in Google Chrome before 31.0.1650.48, Ghostscript, and other products, does not check for certain duplications of component data during the reading of segments that follow Start Of Scan (SOS) JPEG markers, which allows remote attackers to obtain sensitive information from uninitialized memory locations via a crafted JPEG image.
