The SELECT element implementation in Mozilla Firefox before 25.0, Firefox ESR 24.x before 24.1, Thunderbird before 24.1, and SeaMonkey before 2.22 does not properly restrict the nature or placement of HTML within a dropdown menu, which allows remote attackers to spoof the address bar or conduct clickjacking attacks via vectors that trigger navigation off of a page containing this element.

CVE-2014-1538 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2025-11-25 10.0 HIGH N/A
Use-after-free vulnerability in the nsTextEditRules::CreateMozBR function in Mozilla Firefox before 30.0, Firefox ESR 24.x before 24.6, and Thunderbird before 24.6 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors.
CVE-2015-0815 1 Mozilla 2 Firefox, Thunderbird 2025-11-25 7.5 HIGH N/A
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6, and Thunderbird before 31.6 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
CVE-2013-5596 1 Mozilla 4 Firefox, Seamonkey, Thunderbird and 1 more 2025-11-25 6.8 MEDIUM N/A
The cycle collection (CC) implementation in Mozilla Firefox before 25.0, Firefox ESR 24.x before 24.1, Thunderbird before 24.1, and SeaMonkey before 2.22 does not properly determine the thread for release of an image object, which allows remote attackers to execute arbitrary code or cause a denial of service (race condition and application crash) via a large HTML document containing IMG elements, as demonstrated by the Never-Ending Reddit on reddit.com.
CVE-2017-7791 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 5.0 MEDIUM 5.3 MEDIUM
On pages containing an iframe, the "data:" protocol can be used to create a modal alert that will render over arbitrary domains following page navigation, spoofing of the origin of the modal alert from the iframe content. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.
CVE-2014-1493 6 Canonical, Debian, Mozilla and 3 more 16 Ubuntu Linux, Debian Linux, Firefox and 13 more 2025-11-25 10.0 HIGH 9.8 CRITICAL
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 28.0, Firefox ESR 24.x before 24.4, Thunderbird before 24.4, and SeaMonkey before 2.25 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

CVE-2018-5131 4 Canonical, Debian, Mozilla and 1 more 8 Ubuntu Linux, Debian Linux, Firefox and 5 more 2025-11-25 4.3 MEDIUM 5.9 MEDIUM
Under certain circumstances the "fetch()" API can return transient local copies of resources that were sent with a "no-store" or "no-cache" cache header instead of downloading a copy from the network as it should. This can result in previously stored, locally cached data of a website being accessible to users if they share a common profile while browsing. This vulnerability affects Firefox ESR < 52.7 and Firefox < 59.
CVE-2019-11740 3 Canonical, Mozilla, Opensuse 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more 2025-11-25 6.8 MEDIUM 8.8 HIGH
Mozilla developers and community members reported memory safety bugs present in Firefox 68, Firefox ESR 68, and Firefox 60.8. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1.
