CVE-2020-26959 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-12-10 8.8 High
During browser shutdown, reference decrementing could have occured on a previously freed object, resulting in a use-after-free, memory corruption, and a potentially exploitable crash. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26961 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-12-10 6.5 Medium
When DNS over HTTPS is in use, it intentionally filters RFC1918 and related IP ranges from the responses as these do not make sense coming from a DoH resolver. However when an IPv4 address was mapped through IPv6, these addresses were erroneously let through, leading to a potential DNS Rebinding attack. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26958 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-12-10 6.1 Medium
Firefox did not block execution of scripts with incorrect MIME types when the response was intercepted and cached through a ServiceWorker. This could lead to a cross-site script inclusion vulnerability, or a Content Security Policy bypass. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26960 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-12-10 8.8 High
If the Compact() method was called on an nsTArray, the array could have been reallocated without updating other pointers, leading to a potential use-after-free and exploitable crash. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26956 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-12-10 6.1 Medium
In some cases, removing HTML elements during sanitization would keep existing SVG event handlers and therefore lead to XSS. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26953 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-12-10 4.3 Medium
It was possible to cause the browser to enter fullscreen mode without displaying the security UI; thus making it possible to attempt a phishing attack or otherwise confuse the user. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26965 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-12-10 6.5 Medium
Some websites have a feature "Show Password" where clicking a button will change a password field into a textbook field, revealing the typed password. If, when using a software keyboard that remembers user input, a user typed their password and used that feature, the type of the password field was changed, resulting in a keyboard layout change and the possibility for the software keyboard to remember the typed password. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26966 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2020-12-10 6.5 Medium
Searching for a single word from the address bar caused an mDNS request to be sent on the local network searching for a hostname consisting of that string; resulting in an information leak. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26968 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-12-10 8.8 High
Mozilla developers reported memory safety bugs present in Firefox 82 and Firefox ESR 78.4. 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 < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26951 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-12-09 6.1 Medium
A parsing and event loading mismatch in Firefox's SVG code could have allowed load events to fire, even after sanitization. An attacker already capable of exploiting an XSS vulnerability in privileged internal pages could have used this attack to bypass our built-in sanitizer. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2013-2566 4 Canonical, Fujitsu, Mozilla and 1 more 25 Ubuntu Linux, M10-1, M10-1 Firmware and 22 more 2020-11-23 N/A
The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many single-byte biases, which makes it easier for remote attackers to conduct plaintext-recovery attacks via statistical analysis of ciphertext in a large number of sessions that use the same plaintext.
CVE-2020-15664 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-10-13 6.5 Medium
By holding a reference to the eval() function from an about:blank window, a malicious webpage could have gained access to the InstallTrigger object which would allow them to prompt the user to install an extension. Combined with user confusion, this could result in an unintended or malicious extension being installed. This vulnerability affects Firefox < 80, Thunderbird < 78.2, Thunderbird < 68.12, Firefox ESR < 68.12, Firefox ESR < 78.2, and Firefox for Android < 80.
CVE-2020-15669 1 Mozilla 2 Firefox Esr, Thunderbird 2020-10-02 8.8 High
When aborting an operation, such as a fetch, an abort signal may be deleted while alerting the objects to be notified. This results in a use-after-free and we presume that with enough effort it could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.12 and Thunderbird < 68.12.
CVE-2019-11729 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-09-30 N/A
Empty or malformed p256-ECDH public keys may trigger a segmentation fault due values being improperly sanitized before being copied into memory and used. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
CVE-2019-11719 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-09-30 N/A
When importing a curve25519 private key in PKCS#8format with leading 0x00 bytes, it is possible to trigger an out-of-bounds read in the Network Security Services (NSS) library. This could lead to information disclosure. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
CVE-2015-0797 6 Debian, Gstreamer Project, Linux and 3 more 16 Debian Linux, Gstreamer, Linux Kernel and 13 more 2020-09-28 N/A
GStreamer before 1.4.5, as used in Mozilla Firefox before 38.0, Firefox ESR 31.x before 31.7, and Thunderbird before 31.7 on Linux, allows remote attackers to cause a denial of service (buffer over-read and application crash) or possibly execute arbitrary code via crafted H.264 video data in an m4v file.
CVE-2012-3972 6 Canonical, Debian, Mozilla and 3 more 16 Ubuntu Linux, Debian Linux, Firefox and 13 more 2020-09-09 N/A
The format-number functionality in the XSLT implementation in Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, Thunderbird ESR 10.x before 10.0.7, and SeaMonkey before 2.12 allows remote attackers to obtain sensitive information via unspecified vectors that trigger a heap-based buffer over-read.
CVE-2012-3968 5 Canonical, Mozilla, Opensuse and 2 more 15 Ubuntu Linux, Firefox, Firefox Esr and 12 more 2020-08-28 N/A
Use-after-free vulnerability in the WebGL implementation in Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, Thunderbird ESR 10.x before 10.0.7, and SeaMonkey before 2.12 allows remote attackers to execute arbitrary code via vectors related to deletion of a fragment shader by its accessor.
CVE-2012-3961 5 Canonical, Mozilla, Opensuse and 2 more 15 Ubuntu Linux, Firefox, Firefox Esr and 12 more 2020-08-28 N/A
Use-after-free vulnerability in the RangeData implementation in Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, Thunderbird ESR 10.x before 10.0.7, and SeaMonkey before 2.12 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via unspecified vectors.
CVE-2012-3957 5 Canonical, Mozilla, Opensuse and 2 more 15 Ubuntu Linux, Firefox, Firefox Esr and 12 more 2020-08-28 N/A
