CVE-2017-7766 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2019-10-03 4.6 MEDIUM 7.8 HIGH
An attack using manipulation of "updater.ini" contents, used by the Mozilla Windows Updater, and privilege escalation through the Mozilla Maintenance Service to allow for arbitrary file execution and deletion by the Maintenance Service, which has privileged access. Note: This attack requires local system access and only affects Windows. Other operating systems are not affected. This vulnerability affects Firefox ESR < 52.2 and Firefox < 54.
CVE-2017-5409 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2019-10-03 3.6 LOW 5.5 MEDIUM
The Mozilla Windows updater can be called by a non-privileged user to delete an arbitrary local file by passing a special path to the callback parameter through the Mozilla Maintenance Service, which has privileged access. Note: This attack requires local system access and only affects Windows. Other operating systems are not affected. This vulnerability affects Firefox ESR < 45.8 and Firefox < 52.
CVE-2018-12383 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2019-10-03 2.1 LOW 5.5 MEDIUM
If a user saved passwords before Firefox 58 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Firefox 58. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. This vulnerability affects Firefox < 62, Firefox ESR < 60.2.1, and Thunderbird < 60.2.1.
CVE-2018-5174 2 Microsoft, Mozilla 5 Windows 10, Firefox, Firefox Esr and 2 more 2019-10-03 5.0 MEDIUM 7.5 HIGH
In the Windows 10 April 2018 Update, Windows Defender SmartScreen honors the "SEE_MASK_FLAG_NO_UI" flag associated with downloaded files and will not show any UI. Files that are unknown and potentially dangerous will be allowed to run because SmartScreen will not prompt the user for a decision, and if the user is offline all files will be allowed to be opened because Windows won't prompt the user to ask what to do. Firefox incorrectly sets this flag when downloading files, leading to less secure behavior from SmartScreen. Note: this issue only affects Windows 10 users running the April 2018 update or later. It does not affect other Windows users or other operating systems. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.
CVE-2018-12368 2 Microsoft, Mozilla 4 Windows 10, Firefox, Firefox Esr and 1 more 2019-10-03 9.3 HIGH 8.1 HIGH
Windows 10 does not warn users before opening executable files with the SettingContent-ms extension even when they have been downloaded from the internet and have the "Mark of the Web." Without the warning, unsuspecting users unfamiliar with this new file type might run an unwanted executable. This also allows a WebExtension with the limited downloads.open permission to execute arbitrary code without user interaction on Windows 10 systems. *Note: this issue only affects Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Thunderbird < 60, Thunderbird < 52.9, Firefox ESR < 60.1, Firefox ESR < 52.9, and Firefox < 61.
CVE-2017-5462 2 Debian, Mozilla 5 Debian Linux, Firefox, Firefox Esr and 2 more 2019-10-03 5.0 MEDIUM 5.3 MEDIUM
A flaw in DRBG number generation within the Network Security Services (NSS) library where the internal state V does not correctly carry bits over. The NSS library has been updated to fix this issue to address this issue and Firefox ESR 52.1 has been updated with NSS version 3.28.4. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.
CVE-2017-7807 3 Debian, Mozilla, Redhat 10 Debian Linux, Firefox, Firefox Esr and 7 more 2019-10-03 5.8 MEDIUM 8.1 HIGH
A mechanism that uses AppCache to hijack a URL in a domain using fallback by serving the files from a sub-path on the domain. This has been addressed by requiring fallback files be inside the manifest directory. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.
CVE-2017-5456 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2019-10-03 7.5 HIGH 9.8 CRITICAL
A mechanism to bypass file system access protections in the sandbox using the file system request constructor through an IPC message. This allows for read and write access to the local file system. This vulnerability affects Firefox ESR < 52.1 and Firefox < 53.
CVE-2017-5390 3 Debian, Mozilla, Redhat 10 Debian Linux, Firefox, Firefox Esr and 7 more 2019-10-03 7.5 HIGH 9.8 CRITICAL
The JSON viewer in the Developer Tools uses insecure methods to create a communication channel for copying and viewing JSON or HTTP headers data, allowing for potential privilege escalation. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.
CVE-2018-12381 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2019-10-03 5.0 MEDIUM 5.3 MEDIUM
Manually dragging and dropping an Outlook email message into the browser will trigger a page navigation when the message's mail columns are incorrectly interpreted as a URL. *Note: this issue only affects Windows operating systems with Outlook installed. Other operating systems are not affected.*. This vulnerability affects Firefox ESR < 60.2 and Firefox < 62.
CVE-2017-7782 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2019-10-03 5.0 MEDIUM 5.3 MEDIUM
An error in the "WindowsDllDetourPatcher" where a RWX ("Read/Write/Execute") 4k block is allocated but never protected, violating DEP protections.

CVE-2018-12395 4 Canonical, Debian, Mozilla and 1 more 8 Ubuntu Linux, Debian Linux, Firefox and 5 more 2019-10-03 5.0 MEDIUM 7.5 HIGH
By rewriting the Host: request headers using the webRequest API, a WebExtension can bypass domain restrictions through domain fronting. This would allow access to domains that share a host that are otherwise restricted. This vulnerability affects Firefox ESR < 60.3 and Firefox < 63.
CVE-2018-5117 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2019-10-03 5.0 MEDIUM 5.3 MEDIUM
If right-to-left text is used in the addressbar with left-to-right alignment, it is possible in some circumstances to scroll this text to spoof the displayed URL. This issue could result in the wrong URL being displayed as a location, which can mislead users to believe they are on a different site than the one loaded. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58.
CVE-2017-7830 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Firefox Esr and 6 more 2019-10-03 4.3 MEDIUM 6.5 MEDIUM
