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-2019-11741 1 Mozilla 1 Firefox 2024-11-21 6.1 Medium
A compromised sandboxed content process can perform a Universal Cross-site Scripting (UXSS) attack on content from any site it can cause to be loaded in the same process. Because addons.mozilla.org and accounts.firefox.com have close ties to the Firefox product, malicious manipulation of these sites within the browser can potentially be used to modify a user's Firefox configuration. These two sites will now be isolated into their own process and not allowed to be loaded in a standard content process. This vulnerability affects Firefox < 69.
CVE-2019-11739 2 Mozilla, Redhat 2 Thunderbird, Enterprise Linux 2024-11-21 6.5 Medium
Encrypted S/MIME parts in a crafted multipart/alternative message can leak plaintext when included in a a HTML reply/forward. This vulnerability affects Thunderbird < 68.1 and Thunderbird < 60.9.
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-2019-11737 1 Mozilla 1 Firefox 2024-11-21 5.3 Medium
If a wildcard ('*') is specified for the host in Content Security Policy (CSP) directives, any port or path restriction of the directive will be ignored, leading to CSP directives not being properly applied to content. This vulnerability affects Firefox < 69.
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-2019-11734 1 Mozilla 1 Firefox 2024-11-21 9.8 Critical
Mozilla developers and community members reported memory safety bugs present in Firefox 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.
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-2019-11728 2 Mozilla, Opensuse 2 Firefox, Leap 2024-11-21 4.7 Medium
The HTTP Alternative Services header, Alt-Svc, can be used by a malicious site to scan all TCP ports of any host that the accessible to a user when web content is loaded. This vulnerability affects Firefox < 68.
CVE-2019-11727 2 Mozilla, Redhat 3 Firefox, Enterprise Linux, Openshift Do 2024-11-21 N/A
A vulnerability exists where it possible to force Network Security Services (NSS) to sign CertificateVerify with PKCS#1 v1.5 signatures when those are the only ones advertised by server in CertificateRequest in TLS 1.3. PKCS#1 v1.5 signatures should not be used for TLS 1.3 messages. This vulnerability affects Firefox < 68.
CVE-2019-11725 2 Mozilla, Opensuse 2 Firefox, Leap 2024-11-21 6.5 Medium
When a user navigates to site marked as unsafe by the Safebrowsing API, warning messages are displayed and navigation is interrupted but resources from the same site loaded through websockets are not blocked, leading to the loading of unsafe resources and bypassing safebrowsing protections. This vulnerability affects Firefox < 68.
CVE-2019-11724 2 Mozilla, Opensuse 2 Firefox, Leap 2024-11-21 6.1 Medium
Application permissions give additional remote troubleshooting permission to the site input.mozilla.org, which has been retired and now redirects to another site. This additional permission is unnecessary and is a potential vector for malicious attacks. This vulnerability affects Firefox < 68.
CVE-2019-11723 2 Mozilla, Opensuse 2 Firefox, Leap 2024-11-21 7.5 High
A vulnerability exists during the installation of add-ons where the initial fetch ignored the origin attributes of the browsing context. This could leak cookies in private browsing mode or across different "containers" for people who use the Firefox Multi-Account Containers Web Extension. This vulnerability affects Firefox < 68.
CVE-2019-11721 2 Mozilla, Opensuse 2 Firefox, Leap 2024-11-21 6.5 Medium
The unicode latin 'kra' character can be used to spoof a standard 'k' character in the addressbar. This allows for domain spoofing attacks as do not display as punycode text, allowing for user confusion. This vulnerability affects Firefox < 68.
CVE-2019-11720 2 Mozilla, Opensuse 2 Firefox, Leap 2024-11-21 6.1 Medium
Some unicode characters are incorrectly treated as whitespace during the parsing of web content instead of triggering parsing errors. This allows malicious code to then be processed, evading cross-site scripting (XSS) filtering. This vulnerability affects Firefox < 68.
CVE-2019-11718 2 Mozilla, Opensuse 2 Firefox, Leap 2024-11-21 5.3 Medium
Activity Stream can display content from sent from the Snippet Service website. This content is written to innerHTML on the Activity Stream page without sanitization, allowing for a potential access to other information available to the Activity Stream, such as browsing history, if the Snipper Service were compromised. This vulnerability affects Firefox < 68.
