CVE-2020-15671 1 Mozilla 1 Firefox 2021-07-21 2.6 LOW 3.1 LOW
When typing in a password under certain conditions, a race may have occured where the InputContext was not being correctly set for the input field, resulting in the typed password being saved to the keyboard dictionary. This vulnerability affects Firefox for Android < 80.
CVE-2020-15674 1 Mozilla 1 Firefox 2021-07-21 6.8 MEDIUM 8.8 HIGH
Mozilla developers reported memory safety bugs present in Firefox 80. 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 < 81.
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-2020-15675 1 Mozilla 1 Firefox 2021-07-21 6.8 MEDIUM 8.8 HIGH
When processing surfaces, the lifetime may outlive a persistent buffer leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 81.
CVE-2017-5461 1 Mozilla 1 Network Security Services 2021-07-20 7.5 HIGH 9.8 CRITICAL
Mozilla Network Security Services (NSS) before 3.21.4, 3.22.x through 3.28.x before 3.28.4, 3.29.x before 3.29.5, and 3.30.x before 3.30.1 allows remote attackers to cause a denial of service (out-of-bounds write) or possibly have unspecified other impact by leveraging incorrect base64 operations.
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-2021-23991 1 Mozilla 1 Thunderbird 2021-07-08 4.0 MEDIUM 6.8 MEDIUM
If a Thunderbird user has previously imported Alice's OpenPGP key, and Alice has extended the validity period of her key, but Alice's updated key has not yet been imported, an attacker may send an email containing a crafted version of Alice's key with an invalid subkey, Thunderbird might subsequently attempt to use the invalid subkey, and will fail to send encrypted email to Alice. This vulnerability affects Thunderbird < 78.9.1.
CVE-2021-23992 1 Mozilla 1 Thunderbird 2021-07-08 4.3 MEDIUM 4.3 MEDIUM
Thunderbird did not check if the user ID associated with an OpenPGP key has a valid self signature. An attacker may create a crafted version of an OpenPGP key, by either replacing the original user ID, or by adding another user ID. If Thunderbird imports and accepts the crafted key, the Thunderbird user may falsely conclude that the false user ID belongs to the correspondent. This vulnerability affects Thunderbird < 78.9.1.
CVE-2021-23993 1 Mozilla 1 Thunderbird 2021-07-06 4.3 MEDIUM 6.5 MEDIUM
An attacker may perform a DoS attack to prevent a user from sending encrypted email to a correspondent. If an attacker creates a crafted OpenPGP key with a subkey that has an invalid self signature, and the Thunderbird user imports the crafted key, then Thunderbird may try to use the invalid subkey, but the RNP library rejects it from being used, causing encryption to fail. This vulnerability affects Thunderbird < 78.9.1.
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-2021-24002 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2021-07-02 6.8 MEDIUM 8.8 HIGH
When a user clicked on an FTP URL containing encoded newline characters (%0A and %0D), the newlines would have been interpreted as such and allowed arbitrary commands to be sent to the FTP server. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and 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
By utilizing 3D CSS in conjunction with Javascript, content could have been rendered outside the webpage's viewport, resulting in a spoofing attack that could have been used for phishing or other attacks on a user. This vulnerability affects Firefox < 88.
CVE-2021-23994 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2021-07-02 6.8 MEDIUM 8.8 HIGH
A WebGL framebuffer was not initialized early enough, resulting in memory corruption and an out of bound write. This vulnerability affects Firefox ESR < 78.10, Thunderbird < 78.10, and Firefox < 88.
CVE-2021-24000 1 Mozilla 1 Firefox 2021-07-01 2.6 LOW 3.1 LOW
A race condition with requestPointerLock() and setTimeout() could have resulted in a user interacting with one tab when they believed they were on a separate tab. In conjunction with certain elements (such as &lt;input type="file"&gt;) this could have led to an attack where a user was confused about the origin of the webpage and potentially disclosed information they did not intend to. This vulnerability affects Firefox < 88.
CVE-2021-29963 1 Mozilla 1 Firefox 2021-06-30 4.3 MEDIUM 4.3 MEDIUM
Address bar search suggestions in private browsing mode were re-using session data from normal mode. *This bug only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 89.
CVE-2021-29964 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2021-06-30 5.8 MEDIUM 7.1 HIGH
A locally-installed hostile program could send `WM_COPYDATA` messages that Firefox would process incorrectly, leading to an out-of-bounds read. *This bug only affects Firefox on Windows. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 78.11, Firefox < 89, and Firefox ESR < 78.11.
