Multiple Vulnerabilities in Google Android OS Could Allow for Remote Code Execution

Read Time:38 Second

Multiple vulnerabilities have been discovered in the Google Android operating system (OS), the most severe of which could allow for remote code execution. Android is an operating system developed by Google for mobile devices, including, but not limited to, smartphones, tablets, and watches. Successful exploitation of the most severe of these vulnerabilities could allow for remote code execution within the context of a privileged process. Depending on the privileges associated with this application, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. If this application has been configured to have fewer user rights on the system, exploitation of the most severe of these vulnerabilities could have less impact than if it was configured with administrative rights.

Read Time:31 Second

Multiple vulnerabilities have been discovered in Google Chrome, the most severe of which could allow for remote code execution. Google Chrome is a web browser used to access the Internet. Successful exploitation of the most severe of these vulnerabilities could allow an attacker to execute arbitrary code in the context of the browser. Depending on the privileges associated with the application, an attacker could view, change, or delete data. If this application has been configured to have fewer user rights on the system, exploitation of the most severe of these vulnerabilities could have less impact than if it was configured with administrative rights.

WordPress 5.8.3 Security Release

Read Time:1 Minute, 45 Second

This security release features four security fixes. Because this is a security release, it is recommended that you update your sites immediately. All versions since WordPress 3.7 have also been updated.

WordPress 5.8.3 is a short-cycle security release. The next major release will be version 5.9, which is already in the Release Candidate stage.

You can update to WordPress 5.8.3 by downloading from WordPress.org or visiting your Dashboard → Updates and clicking Update Now.

If you have sites that support automatic background updates, they’ve already started the update process.

Security Updates

Four security issues affect WordPress versions between 3.7 and 5.8. If you haven’t yet updated to 5.8, all WordPress versions since 3.7 have also been updated to fix the following security issue (except where noted otherwise):

Props to Karim El Ouerghemmi and Simon Scannell of SonarSource for disclosing an issue with stored XSS through post slugs.Props to Simon Scannell of SonarSource for reporting an issue with Object injection in some multisite installations.Props to ngocnb and khuyenn from GiaoHangTietKiem JSC for working with Trend Micro Zero Day Initiative on reporting a SQL injection vulnerability in WP_Query.Props to Ben Bidner from the WordPress security team for reporting a SQL injection vulnerability in WP_Meta_Query (only relevant to versions 4.1-5.8).

Thank you to all of the reporters above for privately disclosing the vulnerabilities. This gave the security team time to fix the vulnerabilities before WordPress sites could be attacked. Thank you to the members of the WordPress security team for implementing these fixes in WordPress.

For more information, check out the 5.8.3 HelpHub documentation page.

Thanks and props!

The 5.8.3 release was led by @desrosj and @circlecube.

In addition to the security researchers and release squad members mentioned above, thank you to everyone who helped make WordPress 5.8.3 happen:

Alex Concha, Dion Hulse, Dominik Schilling, ehtis, Evan Mullins, Jake Spurlock, Jb Audras, Jonathan Desrosiers, Ian Dunn, Peter Wilson, Sergey Biryukov, vortfu, and zieladam.

[R1] Tenable.sc 5.20.0 Fixes Multiple Vulnerabilities

Read Time:28 Second
Tenable.sc versions 5.14.0 through 5.19.1 were found to contain a remote code execution vulnerability which could allow a remote, unauthenticated attacker to execute code under special circumstances. An attacker would first have to stage a specific file type in the web server root of the Tenable.sc host prior to remote exploitation.

Also, Tenable.sc leverages third-party software to help provide underlying functionality. One of the third-party components (Apache) was found to contain vulnerabilities, and updated versions have been made available by the providers.

Drupal core – Moderately critical – Cross Site Scripting – SA-CORE-2021-011

Read Time:1 Minute, 30 Second
Project: 
Drupal core
Date: 
2021-November-17
Security risk: 
Moderately critical 13∕25 AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:Default
Vulnerability: 
Cross Site Scripting
Description: 

The Drupal project uses the CKEditor library for WYSIWYG editing. CKEditor has released a security update that impacts Drupal, along with a hotfix for that update.

Vulnerabilities are possible if Drupal is configured to allow use of the CKEditor library for WYSIWYG editing. An attacker that can create or edit content (even without access to CKEditor themselves) may be able to exploit one or more Cross-Site Scripting (XSS) vulnerabilities to target users with access to the WYSIWYG CKEditor, including site admins with privileged access.

For more information, see CKEditor’s security advisories:

CVE-2021-41165: HTML comments vulnerability allowing to execute JavaScript code
CVE-2021-41164: Advanced Content Filter (ACF) vulnerability allowing to execute JavaScript code using malformed HTML

This advisory is not covered by Drupal Steward.

Solution: 

Install the latest version:

If you are using Drupal 9.2, update to Drupal 9.2.9.
If you are using Drupal 9.1, update to Drupal 9.1.14.
If you are using Drupal 8.9, update to Drupal 8.9.20.

Versions of Drupal prior to 9.1.x are end-of-life and do not receive security coverage.

Note that Drupal 8 has reached its end of life so this is the final security release provided for Drupal 8.

Drupal 7 core does not include the CKEditor module and therefore is not affected.
