| CVE-2023-4585 | 2 Mozilla, Redhat | 8 Firefox, Firefox Esr, Thunderbird and 5 more | 2025-12-18 | 8.8 High |
| Memory safety bugs present in Firefox 116, Firefox ESR 115.1, and Thunderbird 115.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2. | ||||
| CVE-2023-4583 | 2 Mozilla, Redhat | 8 Firefox, Firefox Esr, Thunderbird and 5 more | 2025-12-18 | 7.5 High |
| When checking if the Browsing Context had been discarded in `HttpBaseChannel`, if the load group was not available then it was assumed to have already been discarded which was not always the case for private channels after the private session had ended. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2. | ||||
| CVE-2023-4580 | 2 Mozilla, Redhat | 8 Firefox, Firefox Esr, Thunderbird and 5 more | 2025-12-18 | 6.5 Medium |
| Push notifications stored on disk in private browsing mode were not being encrypted potentially allowing the leak of sensitive information. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2. | ||||
| CVE-2023-4578 | 2 Mozilla, Redhat | 8 Firefox, Firefox Esr, Thunderbird and 5 more | 2025-12-18 | 6.5 Medium |
| When calling `JS::CheckRegExpSyntax` a Syntax Error could have been set which would end in calling `convertToRuntimeErrorAndClear`. A path in the function could attempt to allocate memory when none is available which would have caused a newly created Out of Memory exception to be mishandled as a Syntax Error. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2. | ||||
| CVE-2023-5732 | 3 Debian, Mozilla, Redhat | 9 Debian Linux, Firefox, Firefox Esr and 6 more | 2025-12-18 | 6.5 Medium |
| An attacker could have created a malicious link using bidirectional characters to spoof the location in the address bar when visited. This vulnerability affects Firefox < 117, Firefox ESR < 115.4, and Thunderbird < 115.4.1. | ||||
| CVE-2023-4577 | 2 Mozilla, Redhat | 8 Firefox, Firefox Esr, Thunderbird and 5 more | 2025-12-18 | 6.5 Medium |
| When `UpdateRegExpStatics` attempted to access `initialStringHeap` it could already have been garbage collected prior to entering the function, which could potentially have led to an exploitable crash. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2. | ||||
| CVE-2023-4584 | 2 Mozilla, Redhat | 8 Firefox, Firefox Esr, Thunderbird and 5 more | 2025-12-18 | 8.8 High |
| Memory safety bugs present in Firefox 116, Firefox ESR 102.14, Firefox ESR 115.1, Thunderbird 102.14, and Thunderbird 115.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. | ||||
| CVE-2023-4581 | 2 Mozilla, Redhat | 8 Firefox, Firefox Esr, Thunderbird and 5 more | 2025-12-18 | 4.3 Medium |
| Excel `.xll` add-in files did not have a blocklist entry in Firefox's executable blocklist which allowed them to be downloaded without any warning of their potential harm. This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. | ||||
| CVE-2023-4576 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2025-12-18 | 8.6 High |
| On Windows, an integer overflow could occur in `RecordedSourceSurfaceCreation` which resulted in a heap buffer overflow potentially leaking sensitive data that could have led to a sandbox escape. *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. | ||||
| CVE-2023-4575 | 2 Mozilla, Redhat | 8 Firefox, Firefox Esr, Thunderbird and 5 more | 2025-12-18 | 6.5 Medium |
| When creating a callback over IPC for showing the File Picker window, multiple of the same callbacks could have been created at a time and eventually all simultaneously destroyed as soon as one of the callbacks finished. This could have led to a use-after-free causing a potentially exploitable crash. This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. | ||||
| CVE-2023-4574 | 2 Mozilla, Redhat | 8 Firefox, Firefox Esr, Thunderbird and 5 more | 2025-12-18 | 6.5 Medium |
| When creating a callback over IPC for showing the Color Picker window, multiple of the same callbacks could have been created at a time and eventually all simultaneously destroyed as soon as one of the callbacks finished. This could have led to a use-after-free causing a potentially exploitable crash. This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. | ||||
| CVE-2023-4573 | 2 Mozilla, Redhat | 8 Firefox, Firefox Esr, Thunderbird and 5 more | 2025-12-18 | 6.5 Medium |
| When receiving rendering data over IPC `mStream` could have been destroyed when initialized, which could have led to a use-after-free causing a potentially exploitable crash. This vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2. | ||||
| CVE-2014-1533 | 2 Mozilla, Redhat | 3 Firefox, Firefox Esr, Enterprise Linux | 2025-11-25 | N/A |
| Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 30.0, Firefox ESR 24.x before 24.6, and Thunderbird before 24.6 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors. | ||||
| CVE-2014-1555 | 2 Mozilla, Redhat | 4 Firefox, Firefox Esr, Thunderbird and 1 more | 2025-11-25 | N/A |
| Use-after-free vulnerability in the nsDocLoader::OnProgress function in Mozilla Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7 allows remote attackers to execute arbitrary code via vectors that trigger a FireOnStateChange event. | ||||
| CVE-2014-1551 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2025-11-25 | N/A |
| Use-after-free vulnerability in the FontTableRec destructor in Mozilla Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7 on Windows allows remote attackers to execute arbitrary code via crafted use of fonts in MathML content, leading to improper handling of a DirectWrite font-face object. | ||||
| CVE-2014-1547 | 2 Mozilla, Redhat | 4 Firefox, Firefox Esr, Thunderbird and 1 more | 2025-11-25 | N/A |
| Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors. | ||||
| CVE-2014-1562 | 2 Mozilla, Redhat | 4 Firefox, Firefox Esr, Thunderbird and 1 more | 2025-11-25 | N/A |
| Unspecified vulnerability in the browser engine in Mozilla Firefox before 32.0, Firefox ESR 24.x before 24.8 and 31.x before 31.1, and Thunderbird 24.x before 24.8 and 31.x before 31.1 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors. | ||||
| CVE-2019-11746 | 2 Mozilla, Redhat | 4 Firefox, Firefox Esr, Thunderbird and 1 more | 2025-11-25 | 8.8 High |
| A use-after-free vulnerability can occur while manipulating video elements if the body is freed while still in use. This results in a potentially exploitable crash. This vulnerability affects Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1. | ||||
| CVE-2014-1556 | 2 Mozilla, Redhat | 4 Firefox, Firefox Esr, Thunderbird and 1 more | 2025-11-25 | N/A |

| CVE-2019-11743 | 2 Mozilla, Redhat | 4 Firefox, Firefox Esr, Thunderbird and 1 more | 2025-11-25 | 3.7 Low |
| Navigation events were not fully adhering to the W3C's "Navigation-Timing Level 2" draft specification in some instances for the unload event, which restricts access to detailed timing attributes to only be same-origin. This resulted in potential cross-origin information exposure of history through timing side-channel attacks. This vulnerability affects Firefox < 69, Thunderbird < 68.1, Thunderbird < 60.9, Firefox ESR < 60.9, and Firefox ESR < 68.1. | ||||
