DRUPAL-CORE-2020-013
drupal/coredrupal/coredrupal/coreThe Drupal project uses the PEAR Archive_Tar library. The PEAR Archive_Tar library has released a security update that impacts Drupal. For more information please see:
Multiple vulnerabilities are possible if Drupal is configured to allow .tar, .tar.gz, .bz2, or .tlz file uploads and processes them.
To mitigate this issue, prevent untrusted users from uploading .tar, .tar.gz, .bz2, or .tlz files.
This is a different issue than SA-CORE-2019-012. Similar configuration changes may mitigate the problem until you are able to patch.

- CVE-2020-28948
Archive_Tar through 1.4.10 allows an unserialization attack because phar: is blocked but PHAR: is not blocked.
Alias, EPSS 84.55% - CVE-2020-28949
Archive_Tar through 1.4.10 has :// filename sanitization only to address phar attacks, and thus any other stream-wrapper attack (such as file:// to overwrite files) can still succeed.
