CVE-2023-5730 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-11-21 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 2024-11-21 N/A 4.3 MEDIUM

CVE-2023-5727 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2024-11-21 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.

CVE-2023-5726 2 Apple, Mozilla 4 Macos, Firefox, Firefox Esr and 1 more 2024-11-21 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-2023-5725 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-11-21 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-2023-5724 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-11-21 N/A 7.5 HIGH
Drivers are not always robust to extremely large draw calls and in some cases this scenario could have led to a crash. This vulnerability affects Firefox < 119, Firefox ESR < 115.4, and Thunderbird < 115.4.1.
CVE-2023-5723 1 Mozilla 1 Firefox 2024-11-21 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-2023-5722 1 Mozilla 1 Firefox 2024-11-21 N/A 5.3 MEDIUM
Using iterative requests an attacker was able to learn the size of an opaque response, as well as the contents of a server-supplied Vary header. This vulnerability affects Firefox < 119.
CVE-2023-5721 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-11-21 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-2023-5496 2 Mozilla, Translator Poqdev Add-on Project 2 Firefox, Translator Poqdev Add-on 2024-11-21 2.6 LOW 3.1 LOW
A vulnerability was found in Translator PoqDev Add-On 1.0.11 on Firefox. It has been rated as problematic. This issue affects some unknown processing of the component Select Text Handler. The manipulation leads to cross site scripting. The attack may be initiated remotely. The complexity of an attack is rather high. The exploitation is known to be difficult. The exploit has been disclosed to the public and may be used. The identifier VDB-241649 was assigned to this vulnerability. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2023-5217 7 Apple, Debian, Fedoraproject and 4 more 12 Ipad Os, Iphone Os, Debian Linux and 9 more 2024-11-21 N/A 8.8 HIGH
Heap buffer overflow in vp8 encoding in libvpx in Google Chrome prior to 117.0.5938.132 and libvpx 1.13.1 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High)
CVE-2023-5176 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-11-21 N/A 9.8 CRITICAL
Memory safety bugs present in Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2. 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 < 118, Firefox ESR < 115.3, and Thunderbird < 115.3.
CVE-2023-5175 1 Mozilla 1 Firefox 2024-11-21 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-2023-5174 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2024-11-21 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-2023-5173 1 Mozilla 1 Firefox 2024-11-21 N/A 7.5 HIGH
In a non-standard configuration of Firefox, an integer overflow could have occurred based on network traffic (possibly under influence of a local unprivileged webpage), leading to an out-of-bounds write to privileged process memory. *This bug only affects Firefox if a non-standard preference allowing non-HTTPS Alternate Services (`network.http.altsvc.oe`) is enabled.* This vulnerability affects Firefox < 118.
CVE-2023-5172 1 Mozilla 1 Firefox 2024-11-21 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-2023-5171 3 Debian, Fedoraproject, Mozilla 5 Debian Linux, Fedora, Firefox and 2 more 2024-11-21 N/A 6.5 MEDIUM
During Ion compilation, a Garbage Collection could have resulted in a use-after-free condition, allowing an attacker to write two NUL bytes, and cause a potentially exploitable crash. This vulnerability affects Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3.
CVE-2023-5170 1 Mozilla 1 Firefox 2024-11-21 N/A 7.4 HIGH
In canvas rendering, a compromised content process could have caused a surface to change unexpectedly, leading to a memory leak of a privileged process. This memory leak could be used to effect a sandbox escape if the correct data was leaked. This vulnerability affects Firefox < 118.
CVE-2023-5169 3 Debian, Fedoraproject, Mozilla 5 Debian Linux, Fedora, Firefox and 2 more 2024-11-21 N/A 6.5 MEDIUM
A compromised content process could have provided malicious data in a `PathRecording` resulting in an out-of-bounds write, leading to a potentially exploitable crash in a privileged process. This vulnerability affects Firefox < 118, Firefox ESR < 115.3, and Thunderbird < 115.3.
