Mozilla Firefox before 4 cannot properly restrict modifications to cookies established in HTTPS sessions, which allows man-in-the-middle attackers to overwrite or delete arbitrary cookies via a Set-Cookie header in an HTTP response, related to lack of the HTTP Strict Transport Security (HSTS) includeSubDomains feature, aka a "cookie forcing" issue.

CRLF injection vulnerability in the nsCookieService::SetCookieStringInternal function in netwerk/cookie/nsCookieService.cpp in Mozilla Firefox before 3.6.18 and 4.x through 4.0.1, and Thunderbird before 3.1.11, allows remote attackers to bypass intended access restrictions via a string containing a \n (newline) character, which is not properly handled in a JavaScript "document.cookie =" expression, a different vulnerability than CVE-2011-2374.

Mozilla Firefox before 3.6.18 and 4.x through 4.0.1, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a multipart/x-mixed-replace image.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 5.0 and Thunderbird through 3.1.11 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 3.6.18 and 4.x through 4.0.1, and Thunderbird before 3.1.11, allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Use-after-free vulnerability in Mozilla Firefox before 3.6.18 and 4.x through 4.0.1, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14, when JavaScript is disabled, allows remote attackers to execute arbitrary code via a crafted XUL document.

Integer overflow in the Array.reduceRight method in Mozilla Firefox before 3.6.18 and 4.x through 4.0.1, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14 allows remote attackers to execute arbitrary code via vectors involving a long JavaScript Array object.

Mozilla Firefox before 5.0 does not properly enforce the whitelist for the xpinstall functionality, which allows remote attackers to trigger an installation dialog for a (1) add-on or (2) theme via unspecified vectors.

Cross-site scripting (XSS) vulnerability in Mozilla Firefox 4.x through 4.0.1 allows remote attackers to inject arbitrary web script or HTML via an SVG element containing an HTML-encoded entity.

The WebGL implementation in Mozilla Firefox 4.x through 4.0.1 does not properly restrict write operations, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via unspecified vectors.

The WebGL implementation in Mozilla Firefox 4.x through 4.0.1 does not properly restrict read operations, which allows remote attackers to obtain sensitive information from GPU memory associated with an arbitrary process, or cause a denial of service (application crash), via unspecified vectors.

The WebGL implementation in Mozilla Firefox 4.x allows remote attackers to obtain screenshots of the windows of arbitrary desktop applications via vectors involving an SVG filter, an IFRAME element, and uninitialized data in graphics memory.

Mozilla Gecko before 5.0, as used in Firefox before 5.0 and Thunderbird before 5.0, does not block use of a cross-domain image as a WebGL texture, which allows remote attackers to obtain approximate copies of arbitrary images via a timing attack involving a crafted WebGL fragment shader.

The X.509 certificate validation functionality in Mozilla Firefox 4.0.x through 4.0.1 does not properly implement single-session security exceptions, which might make it easier for user-assisted remote attackers to spoof an SSL server via an untrusted certificate that triggers potentially unwanted local caching of documents from that server.

Stack-based buffer overflow in the pdfmoz_onmouse function in apps/mozilla/moz_main.c in the MuPDF plug-in 2008.09.02 for Firefox allows remote attackers to execute arbitrary code via a crafted web site.

Unspecified vulnerability in the browser engine in Mozilla Firefox 3.6.x before 3.6.17 and 4.x before 4.0.1, and Thunderbird 3.1.x before 3.1.10, allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox 4.x before 4.0.1 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to gfx/layers/d3d10/ReadbackManagerD3D10.cpp and unknown other vectors.

Unspecified vulnerability in the browser engine in Mozilla Firefox 3.5.x before 3.5.19, 3.6.x before 3.6.17, and 4.x before 4.0.1; Thunderbird before 3.1.10; and SeaMonkey before 2.0.14 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors, a different vulnerability than CVE-2011-0069.

Unspecified vulnerability in the browser engine in Mozilla Firefox 3.5.x before 3.5.19, 3.6.x before 3.6.17, and 4.x before 4.0.1; Thunderbird before 3.1.10; and SeaMonkey before 2.0.14 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors, a different vulnerability than CVE-2011-0070.

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.
