CVE-2023-5175 1 Mozilla 1 Firefox 2024-02-28 N/A 9.8 CRITICAL
During process shutdown, it was possible that an `ImageBitmap` was created that would later be used after being freed from a different codepath, leading to a potentially exploitable crash. This vulnerability affects Firefox < 118.
CVE-2023-5172 1 Mozilla 1 Firefox 2024-02-28 N/A 9.8 CRITICAL
A hashtable in the Ion Engine could have been mutated while there was a live interior reference, leading to a potential use-after-free and exploitable crash. This vulnerability affects Firefox < 118.
CVE-2023-4576 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2024-02-28 N/A 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-2023-3417 2 Debian, Mozilla 2 Debian Linux, Thunderbird 2024-02-28 N/A 7.5 HIGH
Thunderbird allowed the Text Direction Override Unicode Character in filenames. An email attachment could be incorrectly shown as being a document file, while in fact it was an executable file. Newer versions of Thunderbird will strip the character and show the correct file extension. This vulnerability affects Thunderbird < 115.0.1 and Thunderbird < 102.13.1.
CVE-2023-5730 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-02-28 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-2023-5729 1 Mozilla 1 Firefox 2024-02-28 N/A 4.3 MEDIUM
A malicious web site can enter fullscreen mode while simultaneously triggering a WebAuthn prompt. This could have obscured the fullscreen notification and could have been leveraged in a spoofing attack. This vulnerability affects Firefox < 119.
CVE-2023-4056 2 Debian, Mozilla 3 Debian Linux, Firefox, Firefox Esr 2024-02-28 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-2023-4054 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2024-02-28 N/A 5.5 MEDIUM
When opening appref-ms files, Firefox did not warn the user that these files may contain malicious code. *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 116, Firefox ESR < 102.14, Firefox ESR < 115.1, Thunderbird < 102.14, and Thunderbird < 115.1.
CVE-2023-5727 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2024-02-28 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-2023-4052 1 Mozilla 2 Firefox, Firefox Esr 2024-02-28 N/A 6.5 MEDIUM
The Firefox updater created a directory writable by non-privileged users. When uninstalling Firefox, any files in that directory would be recursively deleted with the permissions of the uninstalling user account. This could be combined with creation of a junction (a form of symbolic link) to allow arbitrary file deletion controlled by the non-privileged user. *This bug only affects Firefox on Windows. Other operating systems are unaffected.* This vulnerability affects Firefox < 116, Firefox ESR < 115.1, and Thunderbird < 115.1.
CVE-2023-5726 2 Apple, Mozilla 4 Macos, Firefox, Firefox Esr and 1 more 2024-02-28 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-2023-4579 1 Mozilla 1 Firefox 2024-02-28 N/A 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-2023-4053 1 Mozilla 1 Firefox 2024-02-28 N/A 6.5 MEDIUM
A website could have obscured the full screen notification by using a URL with a scheme handled by an external program, such as a mailto URL. 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-2023-4574 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-02-28 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-2023-4055 2 Debian, Mozilla 3 Debian Linux, Firefox, Firefox Esr 2024-02-28 N/A 7.5 HIGH
When the number of cookies per domain was exceeded in `document.cookie`, the actual cookie jar sent to the host was no longer consistent with expected cookie jar state. This could have caused requests to be sent with some cookies missing. This vulnerability affects Firefox < 116, Firefox ESR < 102.14, and Firefox ESR < 115.1.
CVE-2023-5725 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-02-28 N/A 4.3 MEDIUM
A malicious installed WebExtension could open arbitrary URLs, which under the right circumstance could be leveraged to collect sensitive user data. This vulnerability affects Firefox < 119, Firefox ESR < 115.4, and Thunderbird < 115.4.1.
CVE-2023-4051 1 Mozilla 1 Firefox 2024-02-28 N/A 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-2023-5723 1 Mozilla 1 Firefox 2024-02-28 N/A 5.3 MEDIUM
An attacker with temporary script access to a site could have set a cookie containing invalid characters using `document.cookie` that could have led to unknown errors. This vulnerability affects Firefox < 119.
CVE-2023-5168 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2024-02-28 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-2023-5176 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-02-28 N/A 9.8 CRITICAL
