Mozilla Firefox — свободный браузер на движке Gecko

Mozilla Firefox 4.x through 9.0, Thunderbird 5.0 through 9.0, and SeaMonkey before 2.7 allow remote attackers to bypass the HTML5 frame-navigation policy and replace arbitrary sub-frames by creating a form submission target with a sub-frame's name attribute.

Mozilla Firefox 4.x through 9.0, Thunderbird 5.0 through 9.0, and SeaMonkey before 2.7 do not properly initialize data for image/vnd.microsoft.icon images, which allows remote attackers to obtain potentially sensitive information by reading a PNG image that was created through conversion from an ICO image.

Multiple cross-site scripting (XSS) vulnerabilities in Mozilla Firefox 4.x through 9.0, Thunderbird 5.0 through 9.0, and SeaMonkey before 2.7 allow remote attackers to inject arbitrary web script or HTML via a (1) web page or (2) Firefox extension, related to improper enforcement of XPConnect security restrictions for frame scripts that call untrusted objects.

Mozilla Firefox before 3.6.26 and 4.x through 9.0, Thunderbird before 3.1.18 and 5.0 through 9.0, and SeaMonkey before 2.7 do not properly initialize nsChildView data structures, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted Ogg Vorbis file.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.6.26 and 4.x through 9.0, Thunderbird before 3.1.18 and 5.0 through 9.0, and SeaMonkey before 2.7 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Mozilla Firefox before 3.6.26 and 4.x through 9.0, Thunderbird before 3.1.18 and 5.0 through 9.0, and SeaMonkey before 2.7 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a malformed XSLT stylesheet that is embedded in a document.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 4.x through 9.0, Thunderbird 5.0 through 9.0, and SeaMonkey before 2.7 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

The ASN.1 decoder in the QuickDER decoder in Mozilla Network Security Services (NSS) before 3.13.4, as used in Firefox 4.x through 12.0, Firefox ESR 10.x before 10.0.5, Thunderbird 5.0 through 12.0, Thunderbird ESR 10.x before 10.0.5, and SeaMonkey before 2.10, allows remote attackers to cause a denial of service (application crash) via a zero-length item, as demonstrated by (1) a zero-length basic constraint or (2) a zero-length field in an OCSP response.

The hb_buffer_ensure function in hb-buffer.c in HarfBuzz, as used in Pango 1.28.3, Firefox, and other products, does not verify that memory reallocations succeed, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) or possibly execute arbitrary code via crafted OpenType font data that triggers use of an incorrect index.

Use-after-free vulnerability in Mozilla Firefox before 3.5.19 and 3.6.x before 3.6.17, and SeaMonkey before 2.0.14, allows remote attackers to execute arbitrary code via vectors related to OBJECT's mChannel.
