Drupal Security Team reports:

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

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.

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

The Drupal project uses the third-party library Archive_Tar, which has released a security-related feature 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.
