CVE-2023-4051 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Thunderbird and 5 more 2025-12-18 7.5 High
A website could have obscured the full screen notification by using the file open dialog. This could have led to user confusion and possible spoofing attacks. This vulnerability affects Firefox < 116, Firefox ESR < 115.2, and Thunderbird < 115.2.
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.

CVE-2023-4579 1 Mozilla 1 Firefox 2025-12-18 3.1 Low
Search queries in the default search engine could appear to have been the currently navigated URL if the search query itself was a well formed URL. This could have led to a site spoofing another if it had been maliciously set as the default search engine. This vulnerability affects Firefox < 117.
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

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.

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.

The ConvolveHorizontally function in Skia, as used in Mozilla Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7, does not properly handle the discarding of image data during function execution, which allows remote attackers to execute arbitrary code by triggering prolonged image scaling, as demonstrated by scaling of a high-quality image.
CVE-2014-1556 2 Mozilla, Redhat 4 Firefox, Firefox Esr, Thunderbird and 1 more 2025-11-25 N/A
Mozilla Firefox before 31.0, Firefox ESR 24.x before 24.7, and Thunderbird before 24.7 allow remote attackers to execute arbitrary code via crafted WebGL content constructed with the Cesium JavaScript library.
