CVE-2023-4574 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-12-10 N/A 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-2023-5727 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2023-12-10 N/A 6.5 MEDIUM
The executable file warning was not presented when downloading .msix, .msixbundle, .appx, and .appxbundle files, which can run commands on a user's computer. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.* This vulnerability affects Firefox < 119, Firefox ESR < 115.4, and Thunderbird < 115.4.1.
CVE-2023-4056 2 Debian, Mozilla 3 Debian Linux, Firefox, Firefox Esr 2023-12-10 N/A 9.8 CRITICAL
Memory safety bugs present in Firefox 115, Firefox ESR 115.0, Firefox ESR 102.13, Thunderbird 115.0, and Thunderbird 102.13. 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 < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1.
CVE-2023-4578 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-12-10 N/A 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-2023-37456 1 Mozilla 1 Firefox 2023-12-10 N/A 6.5 MEDIUM
The session restore helper crashed whenever there was no parameter sent to the message handler. This vulnerability affects Firefox for iOS < 115.
CVE-2023-5732 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2023-12-10 N/A 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-2023-5726 2 Apple, Mozilla 4 Macos, Firefox, Firefox Esr and 1 more 2023-12-10 N/A 4.3 MEDIUM
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. *Note: This issue only affected macOS operating systems. Other operating systems are unaffected.* This vulnerability affects Firefox < 119, Firefox ESR < 115.4, and Thunderbird < 115.4.1.
CVE-2023-5730 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2023-12-10 N/A 9.8 CRITICAL
Memory safety bugs present in Firefox 118, Firefox ESR 115.3, and Thunderbird 115.3. 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 < 119, Firefox ESR < 115.4, and Thunderbird < 115.4.1.
CVE-2023-5168 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2023-12-10 N/A 9.8 CRITICAL
A compromised content process could have provided malicious data to `FilterNodeD2D1` resulting in an out-of-bounds write, leading to a potentially exploitable crash in a privileged process. *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3.
CVE-2023-5174 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2023-12-10 N/A 9.8 CRITICAL
If Windows failed to duplicate a handle during process creation, the sandbox code may have inadvertently freed a pointer twice, resulting in a use-after-free and a potentially exploitable crash. *This bug only affects Firefox on Windows when run in non-standard configurations (such as using `runas`). Other operating systems are unaffected.* This vulnerability affects Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3.
CVE-2023-5721 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2023-12-10 N/A 4.3 MEDIUM
It was possible for certain browser prompts and dialogs to be activated or dismissed unintentionally by the user due to an insufficient activation-delay. This vulnerability affects Firefox < 119, Firefox ESR < 115.4, and Thunderbird < 115.4.1.
CVE-2023-4583 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-12-10 N/A 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-2023-4055 2 Debian, Mozilla 3 Debian Linux, Firefox, Firefox Esr 2023-12-10 N/A 7.5 HIGH

CVE-2023-4046 2 Debian, Mozilla 3 Debian Linux, Firefox, Firefox Esr 2023-12-10 N/A 5.3 MEDIUM
In some circumstances, a stale value could have been used for a global variable in WASM JIT analysis. This resulted in incorrect compilation and a potentially exploitable crash in the content process. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1.
CVE-2023-4045 2 Debian, Mozilla 3 Debian Linux, Firefox, Firefox Esr 2023-12-10 N/A 5.3 MEDIUM

CVE-2023-4580 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2023-12-10 N/A 6.5 MEDIUM
