CVE-2024-0751 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-02-02 N/A 8.8 HIGH
A malicious devtools extension could have been used to escalate privileges. This vulnerability affects Firefox < 122, Firefox ESR < 115.7, and Thunderbird < 115.7.
CVE-2024-0753 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-02-02 N/A 6.5 MEDIUM
In specific HSTS configurations an attacker could have bypassed HSTS on a subdomain. This vulnerability affects Firefox < 122, Firefox ESR < 115.7, and Thunderbird < 115.7.
CVE-2024-0755 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-02-02 N/A 8.8 HIGH
Memory safety bugs present in Firefox 121, Firefox ESR 115.6, and Thunderbird 115.6. 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 < 122, Firefox ESR < 115.7, and Thunderbird < 115.7.
CVE-2008-5021 3 Canonical, Debian, Mozilla 5 Ubuntu Linux, Debian Linux, Firefox and 2 more 2024-02-02 9.3 HIGH N/A
nsFrameManager in Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, Thunderbird 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by modifying properties of a file input element while it is still being initialized, then using the blur method to access uninitialized memory.
CVE-2020-6819 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-02-02 6.8 MEDIUM 8.1 HIGH
Under certain conditions, when running the nsDocShell destructor, a race condition can cause a use-after-free. We are aware of targeted attacks in the wild abusing this flaw. This vulnerability affects Thunderbird < 68.7.0, Firefox < 74.0.1, and Firefox ESR < 68.6.1.
CVE-2021-43537 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-02-02 6.8 MEDIUM 8.8 HIGH
An incorrect type conversion of sizes from 64bit to 32bit integers allowed an attacker to corrupt memory leading to a potentially exploitable crash. This vulnerability affects Thunderbird < 91.4.0, Firefox ESR < 91.4.0, and Firefox < 95.
CVE-2023-6864 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-02-02 N/A 8.8 HIGH
Memory safety bugs present in Firefox 120, Firefox ESR 115.5, and Thunderbird 115.5. 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 ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
CVE-2023-6862 2 Debian, Mozilla 3 Debian Linux, Firefox Esr, Thunderbird 2024-02-02 N/A 8.8 HIGH
A use-after-free was identified in the `nsDNSService::Init`. This issue appears to manifest rarely during start-up. This vulnerability affects Firefox ESR < 115.6 and Thunderbird < 115.6.
CVE-2023-6861 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-02-02 N/A 8.8 HIGH
The `nsWindow::PickerOpen(void)` method was susceptible to a heap buffer overflow when running in headless mode. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
CVE-2023-6863 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-02-02 N/A 8.8 HIGH
The `ShutdownObserver()` was susceptible to potentially undefined behavior due to its reliance on a dynamic type that lacked a virtual destructor. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
CVE-2023-6860 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-02-02 N/A 6.5 MEDIUM
The `VideoBridge` allowed any content process to use textures produced by remote decoders. This could be abused to escape the sandbox. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
CVE-2023-6859 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-02-02 N/A 8.8 HIGH
A use-after-free condition affected TLS socket creation when under memory pressure. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
CVE-2023-6858 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-02-02 N/A 8.8 HIGH
Firefox was susceptible to a heap buffer overflow in `nsTextFragment` due to insufficient OOM handling. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
CVE-2023-6857 5 Apple, Debian, Google and 2 more 7 Macos, Debian Linux, Android and 4 more 2024-02-02 N/A 5.3 MEDIUM
When resolving a symlink, a race may occur where the buffer passed to `readlink` may actually be smaller than necessary. *This bug only affects Firefox on Unix-based operating systems (Android, Linux, MacOS). Windows is unaffected.* This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
CVE-2023-6856 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2024-02-02 N/A 8.8 HIGH
The WebGL `DrawElementsInstanced` method was susceptible to a heap buffer overflow when used on systems with the Mesa VM driver. This issue could allow an attacker to perform remote code execution and sandbox escape. This vulnerability affects Firefox ESR < 115.6, Thunderbird < 115.6, and Firefox < 121.
