Project: Drupal core [1]
Date: 2019-May-08
Security risk: *Moderately critical* 14∕25
AC:Complex/A:Admin/CI:All/II:All/E:Theoretical/TD:Uncommon [2]
Vulnerability: Third-party libraries
Description: 
This security release fixes third-party dependencies included in or required
by Drupal core. As described in TYPO3-PSA-2019-007: By-passing protection of
Phar Stream Wrapper Interceptor [3]:
...
In order to intercept file invocations like file_exists or stat on
compromised Phar archives the base name has to be determined and checked
before allowing to be handled by PHP Phar stream handling. [...]
The current implementation is vulnerable to path traversal leading to
scenarios where the Phar archive to be assessed is not the actual
(compromised) file.
Solution: 
Install the latest version:
* If you are using Drupal 8.7, update to Drupal 8.7.1 [4]
   * If you are using Drupal 8.6 or earlier, update to Drupal 8.6.16 [5].
   * If you are using Drupal 7, update to Drupal 7.67 [6].
Versions of Drupal 8 prior to 8.6.x are end-of-life and do not receive
security coverage.
Also see the Drupal core [7] project page.
