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-2017-7758 3 Debian, Mozilla, Redhat 8 Debian Linux, Firefox, Thunderbird and 5 more 2025-11-25 6.4 MEDIUM 9.1 CRITICAL

CVE-2011-3079 3 Google, Mozilla, Opensuse 5 Chrome, Firefox, Seamonkey and 2 more 2025-11-25 10.0 HIGH N/A
The Inter-process Communication (IPC) implementation in Google Chrome before 18.0.1025.168, as used in Mozilla Firefox before 38.0 and other products, does not properly validate messages, which has unspecified impact and attack vectors.
CVE-2018-18505 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Firefox and 7 more 2025-11-25 7.5 HIGH 10.0 CRITICAL
An 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-2014-1587 1 Mozilla 3 Firefox, Seamonkey, Thunderbird 2025-11-25 6.8 MEDIUM N/A
Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 34.0, Firefox ESR 31.x before 31.3, Thunderbird before 31.3, and SeaMonkey before 2.31 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
CVE-2017-7766 2 Microsoft, Mozilla 2 Windows, Firefox 2025-11-25 4.6 MEDIUM 7.8 HIGH
An attack using manipulation of "updater.ini" contents, used by the Mozilla Windows Updater, and privilege escalation through the Mozilla Maintenance Service to allow for arbitrary file execution and deletion by the Maintenance Service, which has privileged access. Note: This attack requires local system access and only affects Windows. Other operating systems are not affected. This vulnerability affects Firefox ESR < 52.2 and Firefox < 54.
