The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4671-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, obtain     sensitive information, bypass the CSS sanitizer, bypass security restrictions, spoof the URL bar, or     execute arbitrary code. (CVE-2020-16042, CVE-2020-26971, CVE-2020-26972, CVE-2020-26793, CVE-2020-26974,     CVE-2020-26976, CVE-2020-26978, CVE-2020-26979, CVE-2020-35113, CVE-2020-35114)

    It was discovered that the proxy.onRequest API did not catch view-source URLs. If a user were tricked in     to installing an extension with the proxy permission and opening View Source, an attacker could     potentially exploit this to obtain sensitive information. (CVE-2020-35111)

An update of the nodejs package has been released.

Multiple security issues were discovered in the Chromium web browser, which could result in the execution of arbitrary code, denial of service or information disclosure.

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

  - Uninitialized Use in V8 in Google Chrome prior to 87.0.4280.88 allowed a remote attacker to obtain     potentially sensitive information from process memory via a crafted HTML page. (CVE-2020-16042)

  - Use after free in WebRTC in Google Chrome prior to 88.0.4324.96 allowed a remote attacker to potentially     exploit heap corruption via a crafted SCTP packet. (CVE-2020-16044)

  - Certain blit values provided by the user were not properly constrained leading to a heap buffer overflow     on some video drivers. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR <     78.6. (CVE-2020-26971)

  - Certain input to the CSS Sanitizer confused it, resulting in incorrect components being removed. This     could have been used as a sanitizer bypass. This vulnerability affects Firefox < 84, Thunderbird < 78.6,     and Firefox ESR < 78.6. (CVE-2020-26973)

  - When flex-basis was used on a table wrapper, a StyleGenericFlexBasis object could have been incorrectly     cast to the wrong type. This resulted in a heap user-after-free, memory corruption, and a potentially     exploitable crash. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
    (CVE-2020-26974)

  - When a HTTPS pages was embedded in a HTTP page, and there was a service worker registered for the former,     the service worker could have intercepted the request for the secure page despite the iframe not being a     secure context due to the (insecure) framing. This vulnerability affects Firefox < 84. (CVE-2020-26976)

  - Using techniques that built on the slipstream research, a malicious webpage could have exposed both an     internal network's hosts as well as services running on the user's local machine. This vulnerability     affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6. (CVE-2020-26978)

  - When an extension with the proxy permission registered to receive <all_urls>, the proxy.onRequest callback     was not triggered for view-source URLs. While web content cannot navigate to such URLs, a user opening     View Source could have inadvertently leaked their IP address. This vulnerability affects Firefox < 84,     Thunderbird < 78.6, and Firefox ESR < 78.6. (CVE-2020-35111)

  - Mozilla developers reported memory safety bugs present in Firefox 83 and Firefox ESR 78.5. 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 < 84, Thunderbird < 78.6, and     Firefox ESR < 78.6. (CVE-2020-35113)

  - If a user clicked into a specifically crafted PDF, the PDF reader could be confused into leaking cross-     origin information, when said information is served as chunked data. This vulnerability affects Firefox <     85, Thunderbird < 78.7, and Firefox ESR < 78.7. (CVE-2021-23953)

  - Using the new logical assignment operators in a JavaScript switch statement could have caused a type     confusion, leading to a memory corruption and a potentially exploitable crash. This vulnerability affects     Firefox < 85, Thunderbird < 78.7, and Firefox ESR < 78.7. (CVE-2021-23954)

  - Performing garbage collection on re-declared JavaScript variables resulted in a user-after-poison, and a     potentially exploitable crash. This vulnerability affects Firefox < 85, Thunderbird < 78.7, and Firefox     ESR < 78.7. (CVE-2021-23960)

  - Mozilla developers reported memory safety bugs present in Firefox 84 and Firefox ESR 78.6. 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 < 85, Thunderbird < 78.7, and     Firefox ESR < 78.7. (CVE-2021-23964)

  - If Content Security Policy blocked frame navigation, the full destination of a redirect served in the     frame was reported in the violation report; as opposed to the original frame URI. This could be used to     leak sensitive information contained in such URIs. This vulnerability affects Firefox < 86, Thunderbird <     78.8, and Firefox ESR < 78.8. (CVE-2021-23968)

  - As specified in the W3C Content Security Policy draft, when creating a violation report, User agents need     to ensure that the source file is the URL requested by the page, pre-redirects. If that's not possible,     user agents need to strip the URL down to an origin to avoid unintentional leakage. Under certain types     of redirects, Firefox incorrectly set the source file to be the destination of the redirects. This was     fixed to be the redirect destination's origin. This vulnerability affects Firefox < 86, Thunderbird <     78.8, and Firefox ESR < 78.8. (CVE-2021-23969)

  - When trying to load a cross-origin resource in an audio/video context a decoding error may have resulted,     and the content of that error may have revealed information about the resource. This vulnerability affects     Firefox < 86, Thunderbird < 78.8, and Firefox ESR < 78.8. (CVE-2021-23973)

  - Mozilla developers reported memory safety bugs present in Firefox 85 and Firefox ESR 78.7. 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 < 86, Thunderbird < 78.8, and     Firefox ESR < 78.8. (CVE-2021-23978)

  - A texture upload of a Pixel Buffer Object could have confused the WebGL code to skip binding the buffer     used to unpack it, resulting in memory corruption and a potentially exploitable information leak or crash.
    This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. (CVE-2021-23981)

  - Using techniques that built on the slipstream research, a malicious webpage could have scanned both an     internal network's hosts as well as services running on the user's local machine utilizing WebRTC     connections. This vulnerability affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9.
    (CVE-2021-23982)

  - A malicious extension could have opened a popup window lacking an address bar. The title of the popup     lacking an address bar should not be fully controllable, but in this situation was. This could have been     used to spoof a website and attempt to trick the user into providing credentials. This vulnerability     affects Firefox ESR < 78.9, Firefox < 87, and Thunderbird < 78.9. (CVE-2021-23984)

  - Mozilla developers and community members reported memory safety bugs present in Firefox 86 and Firefox ESR     78.8. 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 < 78.9,     Firefox < 87, and Thunderbird < 78.9. (CVE-2021-23987)
