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-2018-5096 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Thunderbird and 6 more 2025-11-25 N/A
A use-after-free vulnerability can occur while editing events in form elements on a page, resulting in a potentially exploitable crash. This vulnerability affects Firefox ESR < 52.6 and Thunderbird < 52.6.
CVE-2018-5097 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Firefox and 7 more 2025-11-25 N/A
A use-after-free vulnerability can occur during XSL transformations when the source document for the transformation is manipulated by script content during the transformation. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58.

CVE-2014-1482 7 Canonical, Debian, Fedoraproject and 4 more 18 Ubuntu Linux, Debian Linux, Fedora and 15 more 2025-11-25 8.8 High
RasterImage.cpp in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, and SeaMonkey before 2.24 does not prevent access to discarded data, which allows remote attackers to execute arbitrary code or cause a denial of service (incorrect write operations) via crafted image data, as demonstrated by Goo Create.
CVE-2014-1481 7 Canonical, Debian, Fedoraproject and 4 more 18 Ubuntu Linux, Debian Linux, Fedora and 15 more 2025-11-25 7.5 High

The System Only Wrapper (SOW) implementation in Mozilla Firefox before 27.0, Firefox ESR 24.x before 24.3, Thunderbird before 24.3, and SeaMonkey before 2.24 does not prevent certain cloning operations, which allows remote attackers to bypass intended restrictions on XUL content via vectors involving XBL content scopes.
