Project: Drupal coreVersion: 8.8.x-dev8.7.x-dev7.x-devDate: 2019-December-18Security risk: Critical 17∕25 AC:Basic/A:User/CI:All/II:All/E:Proof/TD:UncommonVulnerability: Multiple vulnerabilitiesDescription: 

The Drupal project uses the third-party library Archive_Tar, which has released a security update that impacts some Drupal configurations.

Multiple vulnerabilities are possible if Drupal is configured to allow .tar, .tar.gz, .bz2 or .tlz file uploads and processes them.

The latest versions of Drupal update Archive_Tar to 1.4.9 to mitigate the file processing vulnerabilities.

Solution: 

Install the latest version:

• If you are using Drupal 7.x, upgrade to Drupal 7.69.
• If you are using Drupal 8.7.x, upgrade to Drupal 8.7.11.
• If you are using Drupal 8.8.x, upgrade to Drupal 8.8.1.

Versions of Drupal 8 prior to 8.7.x are end-of-life and do not receive security coverage.

Project: Drupal coreVersion: 8.8.x-dev8.7.x-devDate: 2019-December-18Security risk: Moderately critical 10∕25 AC:Basic/A:User/CI:Some/II:None/E:Theoretical/TD:DefaultVulnerability: Access bypassDescription: 

The Media Library module has a security vulnerability whereby it doesn't sufficiently restrict access to media items in certain configurations.

Solution: 

• If you are using Drupal 8.7.x, you should upgrade to Drupal 8.7.11.
• If you are using Drupal 8.8.x, you should upgrade to Drupal 8.8.1.

Versions of Drupal 8 prior to 8.7.x are end-of-life and do not receive security coverage.

Alternatively, you may mitigate this vulnerability by unchecking the "Enable advanced UI" checkbox on /admin/config/media/media-library. (This mitigation is not available in 8.7.x.)

Project: Drupal coreVersion: 8.8.x-dev8.7.x-devDate: 2019-December-18Security risk: Moderately critical 14∕25 AC:Basic/A:Admin/CI:Some/II:All/E:Theoretical/TD:DefaultVulnerability: Multiple vulnerabilitiesDescription: 

Drupal 8 core's file_save_upload() function does not strip the leading and trailing dot ('.') from filenames, like Drupal 7 did.

Users with the ability to upload files with any extension in conjunction with contributed modules may be able to use this to upload system files such as .htaccess in order to bypass protections afforded by Drupal's default .htaccess file.

After this fix, file_save_upload() now trims leading and trailing dots from filenames.

Solution: 

Install the latest version:

• If you use Drupal core 8.7.x: 8.7.11
• If you use Drupal core 8.8.x: 8.8.1

Versions of Drupal 8 prior to 8.7.x are end-of-life and do not receive security coverage.

A visit to install.php can cause cached data to become corrupted. This could cause a site to be impaired until caches are rebuilt.

Solution: 

Install the latest version:

• If you are using Drupal 8.7.x, upgrade to Drupal 8.7.11.
• If you are using Drupal 8.8.x, upgrade to Drupal 8.8.1.

Versions of Drupal 8 prior to 8.7.x are end-of-life and do not receive security coverage.

To mitigate this issue in any version of Drupal 8, you can also block access to install.php if it's not required.
