| CVE-2019-17013 | 1 Mozilla | 1 Firefox | 2021-07-21 | 6.8 MEDIUM | 8.8 HIGH |
| Mozilla developers reported memory safety bugs present in Firefox 70. 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 < 71. | |||||
| CVE-2020-12393 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2021-07-21 | 4.6 MEDIUM | 7.8 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. *Note: this issue only affects Firefox on Windows operating systems.*. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. | |||||
| CVE-2019-17014 | 1 Mozilla | 1 Firefox | 2021-07-21 | 4.3 MEDIUM | 7.4 HIGH |
| If an image had not loaded correctly (such as when it is not actually an image), it could be dragged and dropped cross-domain, resulting in a cross-origin information leak. This vulnerability affects Firefox < 71. | |||||
| CVE-2020-15670 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-07-21 | 6.8 MEDIUM | 8.8 HIGH |
| Mozilla developers reported memory safety bugs present in Firefox for Android 79. 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 < 80, Firefox ESR < 78.2, Thunderbird < 78.2, and Firefox for Android < 80. | |||||
| CVE-2020-12408 | 1 Mozilla | 1 Firefox | 2021-07-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| When browsing a document hosted on an IP address, an attacker could insert certain characters to flip domain and path information in the address bar. This vulnerability affects Firefox < 77. | |||||
| CVE-2020-6831 | 4 Canonical, Debian, Mozilla and 1 more | 6 Ubuntu Linux, Debian Linux, Firefox and 3 more | 2021-07-21 | 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-2019-9794 | 2 Microsoft, Mozilla | 4 Windows, Firefox, Firefox Esr and 1 more | 2021-07-21 | 7.5 HIGH | 9.8 CRITICAL |
| A vulnerability was discovered where specific command line arguments are not properly discarded during Firefox invocation as a shell handler for URLs. This could be used to retrieve and execute files whose location is supplied through these command line arguments if Firefox is configured as the default URI handler for a given URI scheme in third party applications and these applications insufficiently sanitize URL data. *Note: This issue only affects Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60.6, Firefox ESR < 60.6, and Firefox < 66. | |||||
| CVE-2020-6821 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-07-21 | 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-2020-15667 | 1 Mozilla | 1 Firefox | 2021-07-21 | 6.8 MEDIUM | 8.8 HIGH |
| When processing a MAR update file, after the signature has been validated, an invalid name length could result in a heap overflow, leading to memory corruption and potentially arbitrary code execution. Within Firefox as released by Mozilla, this issue is only exploitable with the Mozilla-controlled signing key. This vulnerability affects Firefox < 80. | |||||
| CVE-2019-9821 | 1 Mozilla | 1 Firefox | 2021-07-21 | 6.8 MEDIUM | 8.1 HIGH |
| A use-after-free vulnerability can occur in AssertWorkerThread due to a race condition with shared workers. This results in a potentially exploitable crash. This vulnerability affects Firefox < 67. | |||||
| CVE-2020-12404 | 1 Mozilla | 1 Firefox | 2021-07-21 | 4.3 MEDIUM | 4.3 MEDIUM |
| 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 could leak when used for downloading files. This vulnerability affects Firefox for iOS < 26. | |||||
| CVE-2011-0064 | 2 Gnome, Mozilla | 2 Pango, Firefox | 2021-07-14 | 6.8 MEDIUM | N/A |
| The hb_buffer_ensure function in hb-buffer.c in HarfBuzz, as used in Pango 1.28.3, Firefox, and other products, does not verify that memory reallocations succeed, which allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) or possibly execute arbitrary code via crafted OpenType font data that triggers use of an incorrect index. | |||||
| CVE-2021-23998 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-07-02 | 4.3 MEDIUM | 6.5 MEDIUM |
| Through complicated navigations with new windows, an HTTP page could have inherited a secure lock icon from an HTTPS page. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. | |||||
| CVE-2021-23997 | 1 Mozilla | 1 Firefox | 2021-07-02 | 6.8 MEDIUM | 8.8 HIGH |
| Due to unexpected data type conversions, a use-after-free could have occurred when interacting with the font cache. We presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Firefox < 88. | |||||
| CVE-2021-24001 | 1 Mozilla | 1 Firefox | 2021-07-02 | 4.3 MEDIUM | 4.3 MEDIUM |
| A compromised content process could have performed session history manipulations it should not have been able to due to testing infrastructure that was not restricted to testing-only configurations. This vulnerability affects Firefox < 88. | |||||
| CVE-2021-29944 | 1 Mozilla | 1 Firefox | 2021-07-02 | 4.3 MEDIUM | 6.1 MEDIUM |
| Lack of escaping allowed HTML injection when a webpage was viewed in Reader View. While a Content Security Policy prevents direct code execution, HTML injection is still possible. *Note: This issue only affected Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 88. | |||||
| CVE-2021-23995 | 1 Mozilla | 3 Firefox, Firefox Esr, Thunderbird | 2021-07-02 | 5.1 MEDIUM | 8.8 HIGH |
| When Responsive Design Mode was enabled, it used references to objects that were previously freed. We presume that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88. | |||||
| CVE-2021-23996 | 1 Mozilla | 1 Firefox | 2021-07-02 | 4.3 MEDIUM | 6.5 MEDIUM |
