CVE-2018-12371 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-07-12 6.8 MEDIUM 8.8 HIGH
An integer overflow vulnerability in the Skia library when allocating memory for edge builders on some systems with at least 16 GB of RAM. This results in the use of uninitialized memory, resulting in a potentially exploitable crash. This vulnerability affects Firefox ESR < 60.1, Thunderbird < 60, and Firefox < 61.
CVE-2020-12389 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2020-05-27 7.5 HIGH 10.0 CRITICAL
The Firefox content processes did not sufficiently lockdown access control which could result in a sandbox escape. *Note: this issue only affects Firefox on Windows operating systems.*. This vulnerability affects Firefox ESR < 68.8 and Firefox < 76.
CVE-2020-6822 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-05-01 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-2020-6827 2 Google, Mozilla 2 Android, Firefox Esr 2020-05-01 4.3 MEDIUM 4.7 MEDIUM
When following a link that opened an intent://-schemed URL, causing a custom tab to be opened, Firefox for Android could be tricked into displaying the incorrect URI. <br> *Note: This issue only affects Firefox for Android. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 68.7.
CVE-2011-3062 2 Google, Mozilla 6 Chrome, Firefox, Firefox Esr and 3 more 2020-04-14 6.8 MEDIUM N/A
Off-by-one error in the OpenType Sanitizer in Google Chrome before 18.0.1025.142 allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted OpenType file.
CVE-2020-6796 1 Mozilla 2 Firefox, Firefox Esr 2020-03-11 6.8 MEDIUM 8.8 HIGH
A content process could have modified shared memory relating to crash reporting information, crash itself, and cause an out-of-bound write. This could have caused memory corruption and a potentially exploitable crash. This vulnerability affects Firefox < 73 and Firefox < ESR68.5.
CVE-2020-6798 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2020-03-11 4.3 MEDIUM 6.1 MEDIUM
If a template tag was used in a select tag, the parser could be confused and allow JavaScript parsing and execution when it should not be allowed. A site that relied on the browser behaving correctly could suffer a cross-site scripting vulnerability as a result. In general, this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but is potentially a risk in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5.
CVE-2019-17008 2 Mozilla, Opensuse 4 Firefox, Firefox Esr, Thunderbird and 1 more 2020-01-16 6.8 MEDIUM 8.8 HIGH
When using nested workers, a use-after-free could occur during worker destruction. This resulted in a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.
CVE-2019-17016 4 Canonical, Debian, Mozilla and 1 more 9 Ubuntu Linux, Debian Linux, Firefox and 6 more 2020-01-13 4.3 MEDIUM 6.1 MEDIUM
When pasting a &lt;style&gt; tag from the clipboard into a rich text editor, the CSS sanitizer incorrectly rewrites a @namespace rule. This could allow for injection into certain types of websites resulting in data exfiltration. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.
CVE-2019-17017 4 Canonical, Debian, Mozilla and 1 more 9 Ubuntu Linux, Debian Linux, Firefox and 6 more 2020-01-13 6.8 MEDIUM 8.8 HIGH
Due to a missing case handling object types, a type confusion vulnerability could occur, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.
CVE-2019-17015 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2020-01-13 6.8 MEDIUM 8.8 HIGH
During the initialization of a new content process, a pointer offset can be manipulated leading to memory corruption and a potentially exploitable crash in the parent process. *Note: this issue only occurs on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.
CVE-2019-17022 4 Canonical, Debian, Mozilla and 1 more 9 Ubuntu Linux, Debian Linux, Firefox and 6 more 2020-01-13 4.3 MEDIUM 6.1 MEDIUM
When pasting a &lt;style&gt; tag from the clipboard into a rich text editor, the CSS sanitizer does not escape &lt; and &gt; characters. Because the resulting string is pasted directly into the text node of the element this does not result in a direct injection into the webpage; however, if a webpage subsequently copies the node's innerHTML, assigning it to another innerHTML, this would result in an XSS vulnerability. Two WYSIWYG editors were identified with this behavior, more may exist. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.
CVE-2016-5254 2 Mozilla, Oracle 3 Firefox, Firefox Esr, Linux 2019-12-27 7.5 HIGH 9.8 CRITICAL
Use-after-free vulnerability in the nsXULPopupManager::KeyDown function in Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 allows attackers to execute arbitrary code or cause a denial of service (heap memory corruption and application crash) by leveraging keyboard access to use the Alt key during selection of top-level menu items.
CVE-2016-5252 2 Mozilla, Oracle 3 Firefox, Firefox Esr, Linux 2019-12-27 6.8 MEDIUM 8.8 HIGH
Stack-based buffer underflow in the mozilla::gfx::BasePoint4d function in Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 allows remote attackers to execute arbitrary code via crafted two-dimensional graphics data that is mishandled during clipping-region calculations.
CVE-2016-5263 2 Mozilla, Oracle 3 Firefox, Firefox Esr, Linux 2019-12-27 6.8 MEDIUM 8.8 HIGH
The nsDisplayList::HitTest function in Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 mishandles rendering display transformation, which allows remote attackers to execute arbitrary code via a crafted web site that leverages "type confusion."
CVE-2016-5262 2 Mozilla, Oracle 3 Firefox, Firefox Esr, Linux 2019-12-27 4.3 MEDIUM 6.1 MEDIUM
Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 process JavaScript event-handler attributes of a MARQUEE element within a sandboxed IFRAME element that lacks the sandbox="allow-scripts" attribute value, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks via a crafted web site.
CVE-2016-2837 2 Mozilla, Oracle 3 Firefox, Firefox Esr, Linux 2019-12-27 6.8 MEDIUM 6.3 MEDIUM
Heap-based buffer overflow in the ClearKey Content Decryption Module (CDM) in the Encrypted Media Extensions (EME) API in Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 might allow remote attackers to execute arbitrary code by providing a malformed video and leveraging a Gecko Media Plugin (GMP) sandbox bypass.
CVE-2016-5264 2 Mozilla, Oracle 3 Firefox, Firefox Esr, Linux 2019-12-27 6.8 MEDIUM 8.8 HIGH
Use-after-free vulnerability in the nsNodeUtils::NativeAnonymousChildListChange function in Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via an SVG element that is mishandled during effect application.
CVE-2016-2802 5 Mozilla, Opensuse, Oracle and 2 more 7 Firefox, Firefox Esr, Leap and 4 more 2019-12-27 6.8 MEDIUM 8.8 HIGH
The graphite2::TtfUtil::CmapSubtable4NextCodepoint function in Graphite 2 before 1.3.6, as used in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7, allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via a crafted Graphite smart font.
CVE-2016-2801 5 Mozilla, Opensuse, Oracle and 2 more 7 Firefox, Firefox Esr, Leap and 4 more 2019-12-27 6.8 MEDIUM 8.8 HIGH
The graphite2::TtfUtil::CmapSubtable12Lookup function in TtfUtil.cpp in Graphite 2 before 1.3.6, as used in Mozilla Firefox before 45.0 and Firefox ESR 38.x before 38.7, allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via a crafted Graphite smart font, a different vulnerability than CVE-2016-2797.
