The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5816-1 advisory.

  - A compromised web child process could disable web security opening restrictions, leading to a new child     process being spawned within the <code>file://</code> context. Given a reliable exploit primitive, this     new process could be exploited again leading to arbitrary file read.  (CVE-2023-23597)

  - Due to the Firefox GTK wrapper code's use of text/plain for drag data and GTK treating all text/plain     MIMEs containing file URLs as being dragged a website could arbitrarily read a file via a call to     <code>DataTransfer.setData</code>.  (CVE-2023-23598)

  - When copying a network request from the developer tools panel as a curl command the output was not being     properly sanitized and could allow arbitrary commands to be hidden within.  (CVE-2023-23599)

  - Navigations were being allowed when dragging a URL from a cross-origin iframe into the same tab which     could lead to website spoofing attacks  (CVE-2023-23601)

  - A mishandled security check when creating a WebSocket in a WebWorker caused the Content Security Policy     connect-src header to be ignored. This could lead to connections to restricted origins from inside     WebWorkers.  (CVE-2023-23602)

  - Regular expressions used to filter out forbidden properties and values from style directives in calls to     <code>console.log</code> weren't accounting for external URLs. Data could then be potentially exfiltrated     from the browser.  (CVE-2023-23603)

  - A duplicate <code>SystemPrincipal</code> object could be created when parsing a non-system html document     via <code>DOMParser::ParseFromSafeString</code>. This could have lead to bypassing web security checks.
    (CVE-2023-23604)

  - Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 108 and     Firefox ESR 102.6. 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.  (CVE-2023-23605)
