New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


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


The remote Oracle Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2022-0130 advisory.

- Applying a CSS filter effect could have accessed out of bounds memory. This could have lead to a heap- buffer-overflow causing a potentially exploitable crash. (CVE-2022-22738)

- Certain network request objects were freed too early when releasing a network request handle. This could have lead to a use-after-free causing a potentially exploitable crash. (CVE-2022-22740)

- When inserting text while in edit mode, some characters might have lead to out-of-bounds memory access causing a potentially exploitable crash. (CVE-2022-22742)

- When navigating from inside an iframe while requesting fullscreen access, an attacker-controlled tab could have made the browser unable to leave fullscreen mode. (CVE-2022-22743)

- Securitypolicyviolation events could have leaked cross-origin information for frame-ancestors violations (CVE-2022-22745)

- After accepting an untrusted certificate, handling an empty pkcs7 sequence as part of the certificate data could have lead to a crash. This crash is believed to be unexploitable. (CVE-2022-22747)

- It was possible to construct specific XSLT markup that would be able to bypass an iframe sandbox.

- Malicious websites could have tricked users into accepting launching a program to handle an external URL protocol. (CVE-2022-22739)

- When resizing a popup while requesting fullscreen access, the popup would have become unable to leave fullscreen mode. (CVE-2022-22741)

- Malicious websites could have confused Firefox into showing the wrong origin when asking to launch a program and handling an external URL protocol. (CVE-2022-22748)

- Mozilla developers Calixte Denizet, Kershaw Chang, Christian Holler, Jason Kratzer, Gabriele Svelto, Tyson Smith, Simon Giesecke, and Steve Fink reported memory safety bugs present in Firefox 95 and Firefox ESR 91.4. 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. (CVE-2022-22751)

- Constructing audio sinks could have lead to a race condition when playing audio files and closing windows.
This could have lead to a use-after-free causing a potentially exploitable crash. (CVE-2022-22737)

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