Oracle Linux 7 : firefox (ELSA-2023-0296)

high Nessus Plugin ID 170481


The remote Oracle Linux host is missing one or more security updates.


The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2023-0296 advisory.

- Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 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)

- 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 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)

- An out of date library (libusrsctp) contained vulnerabilities that could potentially be exploited. This vulnerability affects Firefox < 108. (CVE-2022-46871)

- 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)

- 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)

- Due to the Thunderbird 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)

- By confusing the browser, the fullscreen notification could have been delayed or suppressed, resulting in potential user confusion or spoofing attacks. This vulnerability affects Firefox < 108. (CVE-2022-46877)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.


Update the affected firefox package.
