CVE-2021-38503The iframe sandbox rules were not correctly applied to XSLT stylesheets, allowing an iframe to bypass restrictions such as executing scripts or navigating the top-level frame. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.
CVE-2019-11708Insufficient vetting of parameters passed with the Prompt:Open IPC message between child and parent processes can result in the non-sandboxed parent process opening web content chosen by a compromised child process. When combined with additional vulnerabilities this could result in executing arbitrary code on the user's computer. This vulnerability affects Firefox ESR < 60.7.2, Firefox < 67.0.4, and Thunderbird < 60.7.2.
CVE-2018-18505An earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authentication to communication between IPC endpoints and server parents during IPC process creation. This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later channels. This could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.
CVE-2008-5500The layout engine in Mozilla Firefox 3.x before 3.0.5 and 2.x before 2.0.0.19, Thunderbird 2.x before 2.0.0.19, and SeaMonkey 1.x before 1.1.14 allows remote attackers to cause a denial of service (crash) and possibly trigger memory corruption via vectors related to (1) a reachable assertion or (2) an integer overflow.
CVE-2008-5052The AppendAttributeValue function in the JavaScript engine in Mozilla 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) via unknown vectors that trigger memory corruption, as demonstrated by e4x/extensions/regress-410192.js.
CVE-2008-5018The JavaScript engine in Mozilla 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) via vectors related to "insufficient class checking" in the Date class.
CVE-2008-5017Integer overflow in xpcom/io/nsEscape.cpp in the browser engine in Mozilla 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) via unknown vectors.
CVE-2008-5014jslock.cpp in Mozilla Firefox 3.x before 3.0.2, 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 the window.__proto__.__proto__ object in a way that causes a lock on a non-native object, which triggers an assertion failure related to the OBJ_IS_NATIVE function.
CVE-2008-4064Multiple unspecified vulnerabilities in Mozilla Firefox 3.x before 3.0.2 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via vectors related to graphics rendering and (1) handling of a long alert messagebox in the cairo_surface_set_device_offset function, (2) integer overflows when handling animated PNG data in the info_callback function in nsPNGDecoder.cpp, and (3) an integer overflow when handling SVG data in the nsSVGFEGaussianBlurElement::SetupPredivide function in nsSVGFilters.cpp.
CVE-2008-4062Multiple unspecified vulnerabilities in Mozilla Firefox before 2.0.0.17 and 3.x before 3.0.2, Thunderbird before 2.0.0.17, and SeaMonkey before 1.1.12 allow 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 and (1) misinterpretation of the characteristics of Namespace and QName in jsxml.c, (2) misuse of signed integers in the nsEscapeCount function in nsEscape.cpp, and (3) interaction of JavaScript garbage collection with certain use of an NPObject in the nsNPObjWrapper::GetNewOrUsed function in nsJSNPRuntime.cpp.
CVE-2008-4061Integer overflow in the MathML component in Mozilla Firefox before 2.0.0.17 and 3.x before 3.0.2, Thunderbird before 2.0.0.17, and SeaMonkey before 1.1.12 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via an mtd element with a large integer value in the rowspan attribute, related to the layout engine.
CVE-2008-2811The block reflow implementation in Mozilla Firefox before 2.0.0.15, Thunderbird 2.0.0.14 and earlier, and SeaMonkey before 1.1.10 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via an image whose display requires more pixels than nscoord_MAX, related to nsBlockFrame::DrainOverflowLines.
CVE-2008-2799Multiple unspecified vulnerabilities in Mozilla Firefox before 2.0.0.15, Thunderbird 2.0.0.14 and earlier, and SeaMonkey before 1.1.10 allow remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via unknown vectors related to the JavaScript engine.
CVE-2008-2798Multiple unspecified vulnerabilities in Mozilla Firefox before 2.0.0.15, Thunderbird 2.0.0.14 and earlier, and SeaMonkey before 1.1.10 allow remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via unknown vectors related to the layout engine.
CVE-2006-4571Multiple unspecified vulnerabilities in Firefox before 1.5.0.7, Thunderbird before 1.5.0.7, and SeaMonkey before 1.0.5 allow remote attackers to cause a denial of service (crash), corrupt memory, and possibly execute arbitrary code via unspecified vectors, some of which involve JavaScript, and possibly large images or plugin data.
CVE-2006-1790A regression fix in Mozilla Firefox 1.0.7 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via the InstallTrigger.install method, which leads to memory corruption.
CVE-2025-4918An attacker was able to perform an out-of-bounds read or write on a JavaScript `Promise` object. This vulnerability affects Firefox < 138.0.4, Firefox ESR < 128.10.1, Firefox ESR < 115.23.1, Thunderbird < 128.10.2, and Thunderbird < 138.0.2.
CVE-2025-12380Starting with Firefox 142, it was possible for a compromised child process to trigger a use-after-free in the GPU or browser process using WebGPU-related IPC calls. This may have been usable to escape the child process sandbox. This vulnerability affects Firefox < 144.0.2.
