| Under certain conditions, when checking the Resist Fingerprinting preference during device orientation checks, a race condition could have caused a use-after-free and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. | ||||
| CVE-2019-17009 | 3 Microsoft, Mozilla, Opensuse | 5 Windows, Firefox, Firefox Esr and 2 more | 2024-11-21 | 7.8 High |
| When running, the updater service wrote status and log files to an unrestricted location; potentially allowing an unprivileged process to locate and exploit a vulnerability in file handling in the updater service. *Note: This attack requires local system access and only affects Windows. Other operating systems are not affected.*. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. | ||||
| CVE-2019-17008 | 3 Mozilla, Opensuse, Redhat | 6 Firefox, Firefox Esr, Thunderbird and 3 more | 2024-11-21 | 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-2019-17005 | 4 Canonical, Mozilla, Opensuse and 1 more | 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more | 2024-11-21 | 8.8 High |
| The plain text serializer used a fixed-size array for the number of <ol> elements it could process; however it was possible to overflow the static-sized array leading to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71. | ||||
| CVE-2019-11764 | 3 Canonical, Mozilla, Redhat | 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more | 2024-11-21 | 8.8 High |
| Mozilla developers and community members reported memory safety bugs present in Firefox 69 and Firefox ESR 68.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. | ||||
| CVE-2019-11763 | 3 Canonical, Mozilla, Redhat | 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more | 2024-11-21 | 6.1 Medium |
| Failure to correctly handle null bytes when processing HTML entities resulted in Firefox incorrectly parsing these entities. This could have led to HTML comment text being treated as HTML which could have led to XSS in a web application under certain conditions. It could have also led to HTML entities being masked from filters - enabling the use of entities to mask the actual characters of interest from filters. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. | ||||
| CVE-2019-11762 | 3 Canonical, Mozilla, Redhat | 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more | 2024-11-21 | 6.1 Medium |
| If two same-origin documents set document.domain differently to become cross-origin, it was possible for them to call arbitrary DOM methods/getters/setters on the now-cross-origin window. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. | ||||
| CVE-2019-11761 | 3 Canonical, Mozilla, Redhat | 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more | 2024-11-21 | 5.4 Medium |
| By using a form with a data URI it was possible to gain access to the privileged JSONView object that had been cloned into content. Impact from exposing this object appears to be minimal, however it was a bypass of existing defense in depth mechanisms. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. | ||||
| CVE-2019-11760 | 3 Canonical, Mozilla, Redhat | 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more | 2024-11-21 | 8.8 High |
| A fixed-size stack buffer could overflow in nrappkit when doing WebRTC signaling. This resulted in a potentially exploitable crash in some instances. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. | ||||
| CVE-2019-11759 | 3 Canonical, Mozilla, Redhat | 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more | 2024-11-21 | 8.8 High |
| An attacker could have caused 4 bytes of HMAC output to be written past the end of a buffer stored on the stack. This could be used by an attacker to execute arbitrary code or more likely lead to a crash. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2. | ||||
| CVE-2019-11758 | 3 Canonical, Mozilla, Redhat | 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more | 2024-11-21 | 8.8 High |
| Mozilla community member Philipp reported a memory safety bug present in Firefox 68 when 360 Total Security was installed. This bug showed evidence of memory corruption in the accessibility engine and we presume that with enough effort that it could be exploited to run arbitrary code. This vulnerability affects Firefox < 69, Thunderbird < 68.2, and Firefox ESR < 68.2. | ||||
| CVE-2019-11757 | 3 Canonical, Mozilla, Redhat | 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more | 2024-11-21 | 8.8 High |
| 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. | ||||
