Mozilla Firefox before 20.0 and SeaMonkey before 2.17, when gfx.color_management.enablev4 is used, do not properly handle color profiles during PNG rendering, which allows remote attackers to obtain sensitive information from process memory or cause a denial of service (memory corruption) via a grayscale PNG image.

Untrusted search path vulnerability in the Mozilla Updater in Mozilla Firefox before 20.0, Firefox ESR 17.x before 17.0.5, Thunderbird before 17.0.5, Thunderbird ESR 17.x before 17.0.5, and SeaMonkey before 2.17 allows local users to gain privileges via a Trojan horse DLL file in an unspecified directory.

Mozilla Firefox before 20.0 and SeaMonkey before 2.17 do not prevent origin spoofing of tab-modal dialogs, which allows remote attackers to conduct phishing attacks via a crafted web site.

Mozilla Firefox before 18.0 on Android and SeaMonkey before 2.15 do not restrict a touch event to a single IFRAME element, which allows remote attackers to obtain sensitive information or possibly conduct cross-site scripting (XSS) attacks via a crafted HTML document.

The New Tab page in Mozilla Firefox before 17.0 uses a privileged context for execution of JavaScript code by bookmarklets, which allows user-assisted remote attackers to run arbitrary programs by leveraging a javascript: URL in a bookmark.

Untrusted search path vulnerability in the installer in Mozilla Firefox before 17.0 and Firefox ESR 10.x before 10.0.11 on Windows allows local users to gain privileges via a Trojan horse DLL in the default downloads directory.

The Style Inspector in Mozilla Firefox before 17.0 and Firefox ESR 10.x before 10.0.11 does not properly restrict the context of HTML markup and Cascading Style Sheets (CSS) token sequences, which allows user-assisted remote attackers to execute arbitrary JavaScript code with chrome privileges via a crafted stylesheet.

The Web Developer Toolbar in Mozilla Firefox before 17.0 executes script with chrome privileges, which allows user-assisted remote attackers to conduct cross-site scripting (XSS) attacks via a crafted string.

The FT2FontEntry::CreateFontEntry function in FreeType, as used in the Android build of Mozilla Firefox before 16.0.1 on CyanogenMod 10, allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unspecified vectors.
