The remote CentOS Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2020:4947 advisory.

  - Mozilla developers and community members reported memory safety bugs present in Firefox 81 and Firefox ESR     78.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some     of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 78.4,     Firefox < 82, and Thunderbird < 78.4. (CVE-2020-15683)

  - Use after free in WebRTC in Google Chrome prior to 86.0.4240.75 allowed a remote attacker to potentially     exploit heap corruption via a crafted HTML page. (CVE-2020-15969)

The remote NewStart CGSL host, running version MAIN 6.02, has thunderbird packages installed that are affected by multiple vulnerabilities:

  - In certain circumstances, the MCallGetProperty opcode can be emitted with unmet assumptions resulting in     an exploitable use-after-free condition. This vulnerability affects Firefox < 82.0.3, Firefox ESR <     78.4.1, and Thunderbird < 78.4.2. (CVE-2020-26950)

  - By exploiting an Open Redirect vulnerability on a website, an attacker could have spoofed the site     displayed in the download file dialog to show the original site (the one suffering from the open redirect)     rather than the site the file was actually downloaded from. This vulnerability affects Firefox < 81,     Thunderbird < 78.3, and Firefox ESR < 78.3. (CVE-2020-15677)

  - Firefox sometimes ran the onload handler for SVG elements that the DOM sanitizer decided to remove,     resulting in JavaScript being executed after pasting attacker-controlled data into a contenteditable     element. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3.
    (CVE-2020-15676)

  - When recursing through graphical layers while scrolling, an iterator may have become invalid, resulting in     a potential use-after-free. This occurs because the function     APZCTreeManager::ComputeClippedCompositionBounds did not follow iterator invalidation rules. This     vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3. (CVE-2020-15678)

  - Mozilla developers reported memory safety bugs present in Firefox 80 and Firefox ESR 78.2. Some of these     bugs showed evidence of memory corruption and we presume that with enough effort some of these could have     been exploited to run arbitrary code. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and     Firefox ESR < 78.3. (CVE-2020-15673)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 81 and Firefox ESR     78.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some     of these could have been exploited to run arbitrary code. This vulnerability affects Firefox ESR < 78.4,     Firefox < 82, and Thunderbird < 78.4. (CVE-2020-15683)

  - Use after free in WebRTC in Google Chrome prior to 86.0.4240.75 allowed a remote attacker to potentially     exploit heap corruption via a crafted HTML page. (CVE-2020-15969)

  - A parsing and event loading mismatch in Firefox's SVG code could have allowed load events to fire, even     after sanitization. An attacker already capable of exploiting an XSS vulnerability in privileged internal     pages could have used this attack to bypass our built-in sanitizer. This vulnerability affects Firefox <     83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26951)

  - Side-channel information leakage in graphics in Google Chrome prior to 87.0.4280.66 allowed a remote     attacker to leak cross-origin data via a crafted HTML page. (CVE-2020-16012)

  - It was possible to cause the browser to enter fullscreen mode without displaying the security UI; thus     making it possible to attempt a phishing attack or otherwise confuse the user. This vulnerability affects     Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26953)

  - In some cases, removing HTML elements during sanitization would keep existing SVG event handlers and     therefore lead to XSS. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird <     78.5. (CVE-2020-26956)

  - Firefox did not block execution of scripts with incorrect MIME types when the response was intercepted and     cached through a ServiceWorker. This could lead to a cross-site script inclusion vulnerability, or a     Content Security Policy bypass. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and     Thunderbird < 78.5. (CVE-2020-26958)

  - During browser shutdown, reference decrementing could have occured on a previously freed object, resulting     in a use-after-free, memory corruption, and a potentially exploitable crash. This vulnerability affects     Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26959)

  - If the Compact() method was called on an nsTArray, the array could have been reallocated without updating     other pointers, leading to a potential use-after-free and exploitable crash. This vulnerability affects     Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26960)

  - When DNS over HTTPS is in use, it intentionally filters RFC1918 and related IP ranges from the responses     as these do not make sense coming from a DoH resolver. However when an IPv4 address was mapped through     IPv6, these addresses were erroneously let through, leading to a potential DNS Rebinding attack. This     vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5. (CVE-2020-26961)

  - Mozilla developers reported memory safety bugs present in Firefox 82 and Firefox ESR 78.4. Some of these     bugs showed evidence of memory corruption and we presume that with enough effort some of these could have     been exploited to run arbitrary code. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and     Thunderbird < 78.5. (CVE-2020-26968)

  - Some websites have a feature Show Password where clicking a button will change a password field into a     textbook field, revealing the typed password. If, when using a software keyboard that remembers user     input, a user typed their password and used that feature, the type of the password field was changed,     resulting in a keyboard layout change and the possibility for the software keyboard to remember the typed     password. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
    (CVE-2020-26965)

  - When reading SMTP server status codes, Thunderbird writes an integer value to a position on the stack that     is intended to contain just one byte. Depending on processor architecture and stack layout, this leads to     stack corruption that may be exploitable. This vulnerability affects Thunderbird < 78.5.1.
    (CVE-2020-26970)
