CVE-2010-1986 2 Microsoft, Mozilla 2 Windows Xp, Firefox 2026-04-29 5.0 MEDIUM N/A
Mozilla Firefox 3.6.3 on Windows XP SP3 allows remote attackers to cause a denial of service (memory consumption and application crash) via JavaScript code that creates multiple arrays containing elements with long string values, and then appends long strings to the content of a P element, related to the gfxWindowsFontGroup::MakeTextRun function in xul.dll, a different vulnerability than CVE-2009-1571.
CVE-2010-2792 2 Mozilla, Redhat 2 Firefox, Spice-xpi 2026-04-29 3.3 LOW N/A
Race condition in the SPICE (aka spice-xpi) plug-in 2.2 for Firefox allows local users to obtain sensitive information, and conduct man-in-the-middle attacks, by providing a UNIX socket for communication between this plug-in and the client (aka qspice-client) in qspice 0.3.0, and then accessing this socket.
CVE-2008-7293 1 Mozilla 1 Firefox 2026-04-29 5.8 MEDIUM N/A
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.
CVE-2012-3973 1 Mozilla 1 Firefox 2026-04-29 7.6 HIGH N/A
The debugger in the developer-tools subsystem in Mozilla Firefox before 15.0, when remote debugging is disabled, does not properly restrict access to the remote-debugging service, which allows remote attackers to execute arbitrary code by leveraging the presence of the HTTPMonitor extension and connecting to that service through the HTTPMonitor port.
CVE-2013-0791 4 Canonical, Mozilla, Oracle and 1 more 12 Ubuntu Linux, Firefox, Network Security Services and 9 more 2026-04-29 5.0 MEDIUM N/A

CVE-2012-0451 1 Mozilla 5 Firefox, Firefox Esr, Seamonkey and 2 more 2026-04-29 4.3 MEDIUM N/A
CRLF injection vulnerability in Mozilla Firefox 4.x through 10.0, Firefox ESR 10.x before 10.0.3, Thunderbird 5.0 through 10.0, Thunderbird ESR 10.x before 10.0.3, and SeaMonkey before 2.8 allows remote web servers to bypass intended Content Security Policy (CSP) restrictions and possibly conduct cross-site scripting (XSS) attacks via crafted HTTP headers.
CVE-2011-2375 1 Mozilla 2 Firefox, Thunderbird 2026-04-29 10.0 HIGH N/A
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.
CVE-2012-0475 1 Mozilla 3 Firefox, Seamonkey, Thunderbird 2026-04-29 2.6 LOW N/A
Mozilla Firefox 4.x through 11.0, Thunderbird 5.0 through 11.0, and SeaMonkey before 2.9 do not properly construct the Origin and Sec-WebSocket-Origin HTTP headers, which might allow remote attackers to bypass an IPv6 literal ACL via a cross-site (1) XMLHttpRequest or (2) WebSocket operation involving a nonstandard port number and an IPv6 address that contains certain zero fields.
CVE-2010-0181 1 Mozilla 2 Firefox, Seamonkey 2026-04-29 4.3 MEDIUM N/A
Mozilla Firefox before 3.5.9 and 3.6.x before 3.6.2, and SeaMonkey before 2.0.4, executes a mail application in situations where an IMG element has a SRC attribute that is a redirect to a mailto: URL, which allows remote attackers to cause a denial of service (excessive application launches) via an HTML document with many images.
CVE-2013-0776 5 Canonical, Debian, Mozilla and 2 more 12 Ubuntu Linux, Debian Linux, Firefox and 9 more 2026-04-29 4.0 MEDIUM N/A
Mozilla Firefox before 19.0, Firefox ESR 17.x before 17.0.3, Thunderbird before 17.0.3, Thunderbird ESR 17.x before 17.0.3, and SeaMonkey before 2.16 allow man-in-the-middle attackers to spoof the address bar by operating a proxy server that provides a 407 HTTP status code accompanied by web script, as demonstrated by a phishing attack on an HTTPS site.
CVE-2012-3968 5 Canonical, Mozilla, Opensuse and 2 more 14 Ubuntu Linux, Firefox, Seamonkey and 11 more 2026-04-29 10.0 HIGH N/A
Use-after-free vulnerability in the WebGL implementation in Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, Thunderbird ESR 10.x before 10.0.7, and SeaMonkey before 2.12 allows remote attackers to execute arbitrary code via vectors related to deletion of a fragment shader by its accessor.
CVE-2011-0085 1 Mozilla 3 Firefox, Seamonkey, Thunderbird 2026-04-29 10.0 HIGH N/A
Use-after-free vulnerability in the nsXULCommandDispatcher function in Mozilla Firefox before 3.6.18, Thunderbird before 3.1.11, and SeaMonkey through 2.0.14 allows remote attackers to execute arbitrary code via a crafted XUL document that dequeues the current command updater.
CVE-2011-3649 2 Microsoft, Mozilla 3 Windows, Firefox, Thunderbird 2026-04-29 2.6 LOW N/A
Mozilla Firefox 7.0 and Thunderbird 7.0, when the Direct2D (aka D2D) API is used on Windows in conjunction with the Azure graphics back-end, allow remote attackers to bypass the Same Origin Policy, and obtain sensitive image data from a different domain, by inserting this data into a canvas. NOTE: this issue exists because of a CVE-2011-2986 regression.
