CVE-2018-18513 1 Mozilla 1 Thunderbird 2020-08-24 5.0 MEDIUM 7.5 HIGH
A crash can occur when processing a crafted S/MIME message or an XPI package containing a crafted signature. This can be used as a denial-of-service (DOS) attack because Thunderbird reopens the last seen message on restart, triggering the crash again. This vulnerability affects Thunderbird < 60.5.
CVE-2018-18498 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2020-08-24 7.5 HIGH 9.8 CRITICAL
A potential vulnerability leading to an integer overflow can occur during buffer size calculations for images when a raw value is used instead of the checked value. This leads to a possible out-of-bounds write. This vulnerability affects Thunderbird < 60.4, Firefox ESR < 60.4, and Firefox < 64.
CVE-2019-11749 1 Mozilla 2 Firefox, Firefox Esr 2020-08-24 4.3 MEDIUM 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-2019-11750 1 Mozilla 2 Firefox, Firefox Esr 2020-08-24 4.3 MEDIUM 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-2018-5095 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2020-08-24 7.5 HIGH 9.8 CRITICAL
An integer overflow vulnerability in the Skia library when allocating memory for edge builders on some systems with at least 8 GB of RAM. This results in the use of uninitialized memory, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58.
CVE-2019-11739 1 Mozilla 1 Thunderbird 2020-08-24 4.3 MEDIUM 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-2018-5122 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2020-08-24 7.5 HIGH 9.8 CRITICAL
A potential integer overflow in the "DoCrypt" function of WebCrypto was identified. If a means was found of exploiting it, it could result in an out-of-bounds write. This vulnerability affects Firefox < 58.
CVE-2018-12391 2 Google, Mozilla 4 Android, Firefox, Firefox Esr and 1 more 2020-08-24 9.3 HIGH 8.8 HIGH
During HTTP Live Stream playback on Firefox for Android, audio data can be accessed across origins in violation of security policies. Because the problem is in the underlying Android service, this issue is addressed by treating all HLS streams as cross-origin and opaque to access. *Note: this issue only affects Firefox for Android. Desktop versions of Firefox are unaffected.*. This vulnerability affects Firefox < 63, Firefox ESR < 60.3, and Thunderbird < 60.3.
CVE-2019-9798 2 Google, Mozilla 2 Android, Firefox 2020-08-24 5.8 MEDIUM 7.4 HIGH
On Android systems, Firefox can load a library from APITRACE_LIB, which is writable by all users and applications. This could allow malicious third party applications to execute a man-in-the-middle attack if a malicious code was written to that location and loaded. *Note: This issue only affects Android. Other operating systems are unaffected.*. This vulnerability affects Firefox < 66.
CVE-2018-12403 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2020-08-24 5.0 MEDIUM 5.3 MEDIUM
If a site is loaded over a HTTPS connection but loads a favicon resource over HTTP, the mixed content warning is not displayed to users. This vulnerability affects Firefox < 63.
CVE-2019-11748 1 Mozilla 2 Firefox, Firefox Esr 2020-08-24 4.3 MEDIUM 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-2019-11700 2 Microsoft, Mozilla 2 Windows, Firefox 2020-08-24 4.3 MEDIUM 6.5 MEDIUM
A hyperlink using the res: protocol can be used to open local files at a known location in Internet Explorer if a user approves execution when prompted. *Note: this issue only occurs on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 67.
CVE-2018-18496 2 Microsoft, Mozilla 2 Windows, Firefox 2020-08-24 6.8 MEDIUM 8.8 HIGH
When the RSS Feed preview about:feeds page is framed within another page, it can be used in concert with scripted content for a clickjacking attack that confuses users into downloading and executing an executable file from a temporary directory. *Note: This issue only affects Windows operating systems. Other operating systems are not affected.*. This vulnerability affects Firefox < 64.
CVE-2018-5160 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2020-08-24 5.0 MEDIUM 7.5 HIGH
WebRTC can use a "WrappedI420Buffer" pixel buffer but the owning image object can be freed while it is still in use. This can result in the WebRTC encoder using uninitialized memory, leading to a potentially exploitable crash. This vulnerability affects Firefox < 60.
CVE-2019-11751 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2020-08-24 6.8 MEDIUM 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-2018-18510 1 Mozilla 1 Firefox 2020-08-24 4.3 MEDIUM 6.5 MEDIUM
The about:crashcontent and about:crashparent pages can be triggered by web content. These pages are used to crash the loaded page or the browser for test purposes. This issue allows for a non-persistent denial of service (DOS) attack by a malicious site which links to these pages. This vulnerability affects Firefox < 64.
CVE-2018-12384 1 Mozilla 1 Network Security Services 2020-08-24 4.3 MEDIUM 5.9 MEDIUM
When handling a SSLv2-compatible ClientHello request, the server doesn't generate a new random value but sends an all-zero value instead. This results in full malleability of the ClientHello for SSLv2 used for TLS 1.2 in all versions prior to NSS 3.39. This does not impact TLS 1.3.
CVE-2019-17009 3 Microsoft, Mozilla, Opensuse 5 Windows, Firefox, Firefox Esr and 2 more 2020-08-24 4.6 MEDIUM 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-2018-12393 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2020-08-24 5.0 MEDIUM 7.5 HIGH
A potential vulnerability was found in 32-bit builds where an integer overflow during the conversion of scripts to an internal UTF-16 representation could result in allocating a buffer too small for the conversion. This leads to a possible out-of-bounds write. *Note: 64-bit builds are not vulnerable to this issue.*. This vulnerability affects Firefox < 63, Firefox ESR < 60.3, and Thunderbird < 60.3.
CVE-2019-11702 2 Microsoft, Mozilla 2 Windows, Firefox 2020-08-24 4.3 MEDIUM 6.5 MEDIUM
A hyperlink using protocols associated with Internet Explorer, such as IE.HTTP:, can be used to open local files at a known location with Internet Explorer if a user approves execution when prompted. *Note: this issue only occurs on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox < 67.0.2.
