Cross-site scripting vulnerability in Address Book of Cybozu Office 10.0.0 to 10.8.4 allows remote attackers to inject an arbitrary script via unspecified vectors. Note that this vulnerability occurs only when using Mozilla Firefox.
CVE-2020-6831 4 Canonical, Debian, Mozilla and 1 more 6 Ubuntu Linux, Debian Linux, Firefox and 3 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0.
CVE-2020-6830 1 Mozilla 1 Firefox 2024-11-21 5.0 MEDIUM 7.5 HIGH
For native-to-JS bridging, the app requires a unique token to be passed that ensures non-app code can't call the bridging functions. That token was being used for JS-to-native also, but it isn't needed in this case, and its usage was also leaking this token. This vulnerability affects Firefox for iOS < 25.
CVE-2020-6829 1 Mozilla 1 Firefox 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; which leaked partial information about the nonce used during signature generation. Given an electro-magnetic trace of a few signature generations, the private key could have been computed. This vulnerability affects Firefox < 80 and Firefox for Android < 80.
CVE-2020-6826 1 Mozilla 1 Firefox 2024-11-21 7.5 HIGH 9.8 CRITICAL
Mozilla developers Tyson Smith, Bob Clary, and Alexandru Michis reported memory safety bugs present in Firefox 74. 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 < 75.
CVE-2020-6825 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 7.5 HIGH 9.8 CRITICAL
Mozilla developers and community members Tyson Smith and Christian Holler reported memory safety bugs present in Firefox 74 and Firefox ESR 68.6. 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 Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75.
CVE-2020-6824 1 Mozilla 1 Firefox 2024-11-21 1.9 LOW 2.8 LOW
Initially, a user opens a Private Browsing Window and generates a password for a site, then closes the Private Browsing Window but leaves Firefox open. Subsequently, if the user had opened a new Private Browsing Window, revisited the same site, and generated a new password - the generated passwords would have been identical, rather than independent. This vulnerability affects Firefox < 75.
CVE-2020-6823 1 Mozilla 1 Firefox 2024-11-21 7.5 HIGH 9.8 CRITICAL
A malicious extension could have called <code>browser.identity.launchWebAuthFlow</code>, controlling the redirect_uri, and through the Promise returned, obtain the Auth code and gain access to the user's account at the service provider. This vulnerability affects Firefox < 75.
CVE-2020-6822 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 6.8 MEDIUM 8.8 HIGH
On 32-bit builds, an out of bounds write could have occurred when processing an image larger than 4 GB in <code>GMPDecodeData</code>. It is possible that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75.
CVE-2020-6821 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 5.0 MEDIUM 7.5 HIGH
When reading from areas partially or fully outside the source resource with WebGL's <code>copyTexSubImage</code> method, the specification requires the returned values be zero. Previously, this memory was uninitialized, leading to potentially sensitive data disclosure. This vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75.
CVE-2020-6820 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 6.8 MEDIUM 8.1 HIGH
Under certain conditions, when handling a ReadableStream, 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-2020-6819 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-11-21 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-2020-6815 1 Mozilla 1 Firefox 2024-11-21 7.5 HIGH 9.8 CRITICAL
Mozilla developers reported memory safety and script safety bugs present in Firefox 73. Some of these bugs showed evidence of memory corruption or escalation of privilege and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 74.
CVE-2020-6814 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
Mozilla developers reported memory safety bugs present in Firefox and Thunderbird 68.5. 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 Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6.
CVE-2020-6813 1 Mozilla 1 Firefox 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
When protecting CSS blocks with the nonce feature of Content Security Policy, the @import statement in the CSS block could allow an attacker to inject arbitrary styles, bypassing the intent of the Content Security Policy. This vulnerability affects Firefox < 74.
CVE-2020-6812 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2024-11-21 5.0 MEDIUM 5.3 MEDIUM
The first time AirPods are connected to an iPhone, they become named after the user's name by default (e.g. Jane Doe's AirPods.) Websites with camera or microphone permission are able to enumerate device names, disclosing the user's name. To resolve this issue, Firefox added a special case that renames devices containing the substring 'AirPods' to simply 'AirPods'. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6.
CVE-2020-6811 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2024-11-21 6.8 MEDIUM 8.8 HIGH
The 'Copy as cURL' feature of Devtools' network tab did not properly escape the HTTP method of a request, which can be controlled by the website. If a user used the 'Copy as Curl' feature and pasted the command into a terminal, it could have resulted in command injection and arbitrary command execution. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6.
