Vulnerability: 
Multiple vulnerabilities
Affected versions: 
>=7.0 <7.69 || >= 8.0.0 <8.7.11 || >= 8.8.0 <8.8.1
Description: 

The Drupal project uses the third-party library Archive_Tar, which has released a security improvement that is needed to protect 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.

Edited to clarify the nature of the upstream release.

Solution: 

Install the latest version:

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

Additional information

All advisories released today:

Updating to the latest Drupal core release will apply the fixes for all the above advisories.

(Note that this SA is the only one in the list that applies to Drupal 7.x)
