The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6010-1 advisory.

  - A website could have obscured the fullscreen notification by using a combination of     <code>window.open</code>, fullscreen requests, <code>window.name</code> assignments, and     <code>setInterval</code> calls. This could have led to user confusion and possible spoofing attacks.
    (CVE-2023-29533)

  - Following a Garbage Collector compaction, weak maps may have been accessed before they were correctly     traced. This resulted in memory corruption and a potentially exploitable crash.  (CVE-2023-29535)

  - An attacker could cause the memory manager to incorrectly free a pointer that addresses attacker-     controlled memory, resulting in an assertion, memory corruption, or a potentially exploitable crash.
    (CVE-2023-29536)

  - Multiple race conditions in the font initialization could have led to memory corruption and execution of     attacker-controlled code.  (CVE-2023-29537)

  - Under specific circumstances a WebExtension may have received a <code>jar:file:///</code> URI instead of a     <code>moz-extension:///</code> URI during a load request. This leaked directory paths on the user's     machine.  (CVE-2023-29538)

  - When handling the filename directive in the Content-Disposition header, the filename would be truncated if     the filename contained a NULL character. This could have led to reflected file download attacks     potentially tricking users to install malware.  (CVE-2023-29539)

  - Using a redirect embedded into <code>sourceMappingUrls</code> could allow for navigation to external     protocol links in sandboxed iframes without <code>allow-top-navigation-to-custom-protocols</code>.
    (CVE-2023-29540)

  - Firefox did not properly handle downloads of files ending in <code>.desktop</code>, which can be     interpreted to run attacker-controlled commands.  This bug only affects Firefox for Linux on certain     Distributions. Other operating systems are unaffected, and Mozilla is unable to enumerate all affected     Linux Distributions.  (CVE-2023-29541)

  - An attacker could have caused memory corruption and a potentially exploitable use-after-free of a pointer     in a global object's debugger vector.  (CVE-2023-29543)

  - If multiple instances of resource exhaustion occurred at the incorrect time, the garbage collector could     have caused memory corruption and a potentially exploitable crash.  (CVE-2023-29544)

  - When a secure cookie existed in the Firefox cookie jar an insecure cookie for the same domain could have     been created, when it should have silently failed.  This could have led to a desynchronization in expected     results when reading from the secure cookie.  (CVE-2023-29547)

  - A wrong lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result.
    (CVE-2023-29548)

  - Under certain circumstances, a call to the <code>bind</code> function may have resulted in the incorrect     realm.  This may have created a vulnerability relating to JavaScript-implemented sandboxes such as SES.
    (CVE-2023-29549)

  - Mozilla developers Randell Jesup, Andrew Osmond, Sebastian Hengst, Andrew McCreight, and the Mozilla     Fuzzing Team reported memory safety bugs present in Firefox 111 and Firefox ESR 102.9. 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.  (CVE-2023-29550)

  - Mozilla developers Randell Jesup, Andrew McCreight, Gabriele Svelto, and the Mozilla Fuzzing Team reported     memory safety bugs present in Firefox 111. 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.
    (CVE-2023-29551)

  - Unexpected data returned from the Safe Browsing API could have led to memory corruption and a potentially     exploitable crash.  (CVE-2023-1945)

  - matrix-js-sdk is a Matrix messaging protocol Client-Server SDK for JavaScript. In versions prior to 24.0.0     events sent with special strings in key places can temporarily disrupt or impede the matrix-js-sdk from     functioning properly, potentially impacting the consumer's ability to process data safely. Note that the     matrix-js-sdk can appear to be operating normally but be excluding or corrupting runtime data presented to     the consumer. This vulnerability is distinct from GHSA-rfv9-x7hh-xc32 which covers a similar issue. The     issue has been patched in matrix-js-sdk 24.0.0 and users are advised to upgrade. There are no known     workarounds for this vulnerability. (CVE-2023-28427)
