|---|---|---|---|---|
| CVE-2009-1309 | 2 Mozilla, Redhat | 4 Firefox, Seamonkey, Thunderbird and 1 more | 2026-04-23 | N/A |
| Mozilla Firefox before 3.0.9, Thunderbird, and SeaMonkey do not properly implement the Same Origin Policy for (1) XMLHttpRequest, involving a mismatch for a document's principal, and (2) XPCNativeWrapper.toString, involving an incorrect __proto__ scope, which allows remote attackers to conduct cross-site scripting (XSS) attacks and possibly other attacks via a crafted document. | ||||
| CVE-2009-2469 | 2 Mozilla, Redhat | 2 Firefox, Enterprise Linux | 2026-04-23 | N/A |
| Mozilla Firefox before 3.0.12 does not properly handle an SVG element that has a property with a watch function and an __defineSetter__ function, which allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted document, related to a certain pointer misinterpretation. | ||||
| CVE-2008-5021 | 8 Canonical, Debian, Fedoraproject and 5 more | 14 Ubuntu Linux, Debian Linux, Fedora and 11 more | 2026-04-23 | N/A |
| nsFrameManager in Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by modifying properties of a file input element while it is still being initialized, then using the blur method to access uninitialized memory. | ||||
| CVE-2009-3389 | 1 Mozilla | 2 Firefox, Seamonkey | 2026-04-23 | N/A |
| Integer overflow in libtheora in Xiph.Org Theora before 1.1, as used in Mozilla Firefox 3.5 before 3.5.6 and SeaMonkey before 2.0.1, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a video with large dimensions. | ||||
| CVE-2008-0592 | 2 Mozilla, Redhat | 3 Firefox, Seamonkey, Enterprise Linux | 2026-04-23 | N/A |
| Mozilla Firefox before 2.0.0.12 and SeaMonkey before 1.1.8 allows user-assisted remote attackers to cause a denial of service via a plain .txt file with a "Content-Disposition: attachment" and an invalid "Content-Type: plain/text," which prevents Firefox from rendering future plain text files within the browser. | ||||
| CVE-2008-4324 | 2 Microsoft, Mozilla | 2 Windows Xp, Firefox | 2026-04-23 | N/A |
| The user interface event dispatcher in Mozilla Firefox 3.0.3 on Windows XP SP2 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a series of keypress, click, onkeydown, onkeyup, onmousedown, and onmouseup events. NOTE: it was later reported that Firefox 3.0.2 on Mac OS X 10.5 is also affected. | ||||
| CVE-2009-0356 | 2 Mozilla, Redhat | 3 Firefox, Seamonkey, Enterprise Linux | 2026-04-23 | N/A |
| 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-2008-4066 | 2 Mozilla, Redhat | 2 Firefox, Enterprise Linux | 2026-04-23 | N/A |
| Mozilla Firefox 2.0.0.14, and other versions before 2.0.0.17, allows remote attackers to bypass cross-site scripting (XSS) protection mechanisms and conduct XSS attacks via HTML-escaped low surrogate characters that are ignored by the HTML parser, as demonstrated by a "jav�ascript" sequence, aka "HTML escaped low surrogates bug." | ||||
| CVE-2009-0353 | 2 Mozilla, Redhat | 4 Firefox, Seamonkey, Thunderbird and 1 more | 2026-04-23 | N/A |
| Unspecified vulnerability in Mozilla Firefox 3.x before 3.0.6, Thunderbird before 2.0.0.21, and SeaMonkey before 1.1.15 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to the JavaScript engine. | ||||
| CVE-2009-3983 | 2 Mozilla, Redhat | 4 Firefox, Seamonkey, Thunderbird and 1 more | 2026-04-23 | N/A |
| Mozilla Firefox before 3.0.16 and 3.5.x before 3.5.6, and SeaMonkey before 2.0.1, allows remote attackers to send authenticated requests to arbitrary applications by replaying the NTLM credentials of a browser user. | ||||
| CVE-2008-5822 | 1 Mozilla | 2 Firefox, Libxul | 2026-04-23 | N/A |
| Memory leak in Libxul, as used in Mozilla Firefox 3.0.5 and other products, allows remote attackers to cause a denial of service (memory consumption and browser hang) via a long CLASS attribute in an HR element in an HTML document. | ||||
| CVE-2007-1116 | 1 Mozilla | 1 Firefox | 2026-04-23 | N/A |
| The CheckLoadURI function in Mozilla Firefox 1.8 lists the about: URI as a ChromeProtocol and can be loaded via JavaScript, which allows remote attackers to obtain sensitive information by querying the browser's session history. | ||||
| CVE-2009-3010 | 1 Mozilla | 3 Firefox, Mozilla, Seamonkey | 2026-04-23 | N/A |
| Mozilla Firefox 3.0.13 and earlier, 3.5, 3.6 a1 pre, and 3.7 a1 pre; SeaMonkey 1.1.17; and Mozilla 1.7.x and earlier do not properly block data: URIs in Refresh headers in HTTP responses, which allows remote attackers to conduct cross-site scripting (XSS) attacks via vectors related to (1) injecting a Refresh header that contains JavaScript sequences in a data:text/html URI or (2) entering a data:text/html URI with JavaScript sequences when specifying the content of a Refresh header. NOTE: in some product versions, the JavaScript executes outside of the context of the HTTP site. | ||||
| CVE-2007-5339 | 2 Mozilla, Redhat | 4 Firefox, Seamonkey, Thunderbird and 1 more | 2026-04-23 | N/A |
| Multiple vulnerabilities in Mozilla Firefox before 2.0.0.8, Thunderbird before 2.0.0.8, and SeaMonkey before 1.1.5 allow remote attackers to cause a denial of service (crash) via crafted HTML that triggers memory corruption or assert errors. | ||||
