When following the value's prototype chain, it was possible to retain a reference to a locale, delete it, and subsequently reference it. This resulted in a use-after-free and a potentially exploitable crash. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.
CVE-2019-11751 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2024-11-21 8.8 High
Logging-related command line parameters are not properly sanitized when Firefox is launched by another program, such as when a user clicks on malicious links in a chat application. This can be used to write a log file to an arbitrary location such as the Windows 'Startup' folder. <br>*Note: this issue only affects Firefox on Windows operating systems.*. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1.
CVE-2019-11750 2 Mozilla, Redhat 3 Firefox, Firefox Esr, Enterprise Linux 2024-11-21 6.5 Medium
A type confusion vulnerability exists in Spidermonkey, which results in a non-exploitable crash. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1.
CVE-2019-11749 2 Mozilla, Redhat 3 Firefox, Firefox Esr, Enterprise Linux 2024-11-21 4.3 Medium
A vulnerability exists in WebRTC where malicious web content can use probing techniques on the getUserMedia API using constraints to reveal device properties of cameras on the system without triggering a user prompt or notification. This allows for the potential fingerprinting of users. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1.
CVE-2019-11748 2 Mozilla, Redhat 3 Firefox, Firefox Esr, Enterprise Linux 2024-11-21 6.5 Medium
WebRTC in Firefox will honor persisted permissions given to sites for access to microphone and camera resources even when in a third-party context. In light of recent high profile vulnerabilities in other software, a decision was made to no longer persist these permissions. This avoids the possibility of trusted WebRTC resources being invisibly embedded in web content and abusing permissions previously given by users. Users will now be prompted for permissions on each use. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1.
CVE-2019-11747 2 Mozilla, Redhat 3 Firefox, Firefox Esr, Enterprise Linux 2024-11-21 6.5 Medium
The "Forget about this site" feature in the History pane is intended to remove all saved user data that indicates a user has visited a site. This includes removing any HTTP Strict Transport Security (HSTS) settings received from sites that use it. Due to a bug, sites on the pre-load list also have their HSTS setting removed. On the next visit to that site if the user specifies an http: URL rather than secure https: they will not be protected by the pre-loaded HSTS setting. After that visit the site's HSTS setting will be restored. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1.
CVE-2019-11745 6 Canonical, Debian, Mozilla and 3 more 29 Ubuntu Linux, Debian Linux, Firefox and 26 more 2024-11-21 8.8 High
When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the block size, a small out of bounds write could occur. This could have caused heap corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.
CVE-2019-11738 3 Mozilla, Opensuse, Redhat 4 Firefox, Firefox Esr, Leap and 1 more 2024-11-21 6.3 Medium
If a Content Security Policy (CSP) directive is defined that uses a hash-based source that takes the empty string as input, execution of any javascript: URIs will be allowed. This could allow for malicious JavaScript content to be run, bypassing CSP permissions. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1.
CVE-2019-11736 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2024-11-21 7.0 High
The Mozilla Maintenance Service does not guard against files being hardlinked to another file in the updates directory, allowing for the replacement of local files, including the Maintenance Service executable, which is run with privileged access. Additionally, there was a race condition during checks for junctions and symbolic links by the Maintenance Service, allowing for potential local file and directory manipulation to be undetected in some circumstances. This allows for potential privilege escalation by a user with unprivileged local access. <br>*Note: These attacks requires local system access and only affects Windows. Other operating systems are not affected.*. This vulnerability affects Firefox < 69 and Firefox ESR < 68.1.
CVE-2019-11735 3 Mozilla, Opensuse, Redhat 4 Firefox, Firefox Esr, Leap and 1 more 2024-11-21 8.8 High
Mozilla developers and community members reported memory safety bugs present in Firefox 68 and Firefox ESR 68. 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 Firefox < 69 and Firefox ESR < 68.1.
CVE-2019-11730 5 Debian, Mozilla, Opensuse and 2 more 8 Debian Linux, Firefox, Firefox Esr and 5 more 2024-11-21 6.5 Medium
A vulnerability exists where if a user opens a locally saved HTML file, this file can use file: URIs to access other files in the same directory or sub-directories if the names are known or guessed. The Fetch API can then be used to read the contents of any files stored in these directories and they may uploaded to a server. It was demonstrated that in combination with a popular Android messaging app, if a malicious HTML attachment is sent to a user and they opened that attachment in Firefox, due to that app's predictable pattern for locally-saved file names, it is possible to read attachments the victim received from other correspondents. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
CVE-2019-11691 2 Mozilla, Redhat 4 Firefox, Firefox Esr, Thunderbird and 1 more 2024-11-21 N/A
A use-after-free vulnerability can occur when working with XMLHttpRequest (XHR) in an event loop, causing the XHR main thread to be called after it has been freed. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 60.7, Firefox < 67, and Firefox ESR < 60.7.
