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-2023-5173 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-2023-5171 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.
CVE-2023-50762 2 Debian, Mozilla 2 Debian Linux, Thunderbird 2024-11-21 N/A 4.3 MEDIUM
When processing a PGP/MIME payload that contains digitally signed text, the first paragraph of the text was never shown to the user. This is because the text was interpreted as a MIME message and the first paragraph was always treated as an email header section. A digitally signed text from a different context, such as a signed GIT commit, could be used to spoof an email message. This vulnerability affects Thunderbird < 115.6.
CVE-2023-50761 2 Debian, Mozilla 2 Debian Linux, Thunderbird 2024-11-21 N/A 4.3 MEDIUM
The signature of a digitally signed S/MIME email message may optionally specify the signature creation date and time. If present, Thunderbird did not compare the signature creation date with the message date and time, and displayed a valid signature despite a date or time mismatch. This could be used to give recipients the impression that a message was sent at a different date or time. This vulnerability affects Thunderbird < 115.6.
CVE-2023-4585 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 N/A 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-2023-4584 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 N/A 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-2023-4583 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 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-2023-4582 2 Apple, Mozilla 4 Macos, Firefox, Firefox Esr and 1 more 2024-11-21 N/A 8.8 HIGH
Due to large allocation checks in Angle for glsl shaders being too lenient a buffer overflow could have occured when allocating too much private shader memory on mac OS. *This bug only affects Firefox on macOS. Other operating systems are unaffected.* This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2.
CVE-2023-4581 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 N/A 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-2023-4580 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 N/A 6.5 MEDIUM
Push notifications stored on disk in private browsing mode were not being encrypted potentially allowing the leak of sensitive information. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2.
CVE-2023-4579 1 Mozilla 1 Firefox 2024-11-21 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-2023-4578 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 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.
