Firefox will accept any registered Program ID as an external protocol handler and offer to launch this local application when given a matching URL on Windows operating systems. This should only happen if the program has specifically registered itself as a "URL Handler" in the Windows registry. *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-2019-9807 1 Mozilla 1 Firefox 2019-04-29 4.3 MEDIUM 4.3 MEDIUM
When arbitrary text is sent over an FTP connection and a page reload is initiated, it is possible to create a modal alert message with this text as the content. This could potentially be used for social engineering attacks. This vulnerability affects Firefox < 66.
CVE-2019-9808 1 Mozilla 1 Firefox 2019-04-29 5.0 MEDIUM 5.3 MEDIUM
If WebRTC permission is requested from documents with data: or blob: URLs, the permission notifications do not properly display the originating domain.

CVE-2019-9809 1 Mozilla 1 Firefox 2019-04-29 5.0 MEDIUM 7.5 HIGH
If the source for resources on a page is through an FTP connection, it is possible to trigger a series of modal alert messages for these resources through invalid credentials or locations. These messages cannot be immediately dismissed, allowing for a denial of service (DOS) attack. This vulnerability affects Firefox < 66.
CVE-2019-9806 1 Mozilla 1 Firefox 2019-04-29 5.0 MEDIUM 7.5 HIGH
A vulnerability exists during authorization prompting for FTP transaction where successive modal prompts are displayed and cannot be immediately dismissed. This allows for a denial of service (DOS) attack. This vulnerability affects Firefox < 66.
CVE-2018-5124 1 Mozilla 1 Firefox 2019-04-29 4.3 MEDIUM 6.1 MEDIUM
Unsanitized output in the browser UI leaves HTML tags in place and can result in arbitrary code execution in Firefox before version 58.0.1.
CVE-2018-18512 1 Mozilla 1 Thunderbird 2019-04-26 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur while playing a sound notification in Thunderbird. The memory storing the sound data is immediately freed, although the sound is still being played asynchronously, leading to a potentially exploitable crash. This vulnerability affects Thunderbird < 60.5.
CVE-2015-0831 3 Canonical, Mozilla, Redhat 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more 2019-04-22 6.8 MEDIUM N/A
Use-after-free vulnerability in the mozilla::dom::IndexedDB::IDBObjectStore::CreateIndex function in Mozilla Firefox before 36.0, Firefox ESR 31.x before 31.5, and Thunderbird before 31.5 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via crafted content that is improperly handled during IndexedDB index creation.
CVE-2017-7771 2 Mozilla, Sil 2 Firefox, Graphite2 2019-04-15 5.8 MEDIUM 8.1 HIGH
Out-of-bounds read in Graphite2 Library in Firefox before 54 in graphite2::Pass::readPass function.
CVE-2017-7772 2 Mozilla, Sil 2 Firefox, Graphite2 2019-04-15 6.8 MEDIUM 8.8 HIGH
Heap-based Buffer Overflow in Graphite2 library in Firefox before 54 in lz4::decompress function.
CVE-2017-7776 2 Mozilla, Sil 2 Firefox, Graphite2 2019-04-15 5.8 MEDIUM 8.1 HIGH
Heap-based Buffer Overflow read in Graphite2 library in Firefox before 54 in graphite2::Silf::getClassGlyph.

Use of uninitialized memory in Graphite2 library in Firefox before 54 in graphite2::GlyphCache::Loader::read_glyph function.
CVE-2017-7773 2 Mozilla, Sil 2 Firefox, Graphite2 2019-04-15 6.8 MEDIUM 8.8 HIGH
Heap-based Buffer Overflow write in Graphite2 library in Firefox before 54 in lz4::decompress src/Decompressor.
CVE-2018-18501 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Firefox and 7 more 2019-04-02 7.5 HIGH 9.8 CRITICAL
Mozilla developers and community members reported memory safety bugs present in Firefox 64 and Firefox ESR 60.4. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.
CVE-2018-18500 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2019-04-02 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur while parsing an HTML5 stream in concert with custom HTML elements. This results in the stream parser object being freed while still in use, leading to a potentially exploitable crash. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.
CVE-2018-5184 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Thunderbird and 8 more 2019-03-13 5.0 MEDIUM 7.5 HIGH

CVE-2018-5145 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Firefox Esr and 7 more 2019-03-13 7.5 HIGH 9.8 CRITICAL
Memory safety bugs were reported in Firefox ESR 52.6. These bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox ESR < 52.7 and Thunderbird < 52.7.
CVE-2018-5150 4 Canonical, Debian, Mozilla and 1 more 12 Ubuntu Linux, Debian Linux, Firefox and 9 more 2019-03-13 7.5 HIGH 9.8 CRITICAL
Memory safety bugs were reported in Firefox 59, Firefox ESR 52.7, and Thunderbird 52.7. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.
CVE-2018-5157 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Firefox and 7 more 2019-03-13 5.0 MEDIUM 7.5 HIGH
Same-origin protections for the PDF viewer can be bypassed, allowing a malicious site to intercept messages meant for the viewer. This could allow the site to retrieve PDF files restricted to viewing by an authenticated user on a third-party website. This vulnerability affects Firefox ESR < 52.8 and Firefox < 60.
