Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2020-11-27 17:07:01 UTC
Drupal reports RCE via certain tarball archive upload due to CVE-2020-28948 and CVE-2020-28949.

CVE-2020-28948:

Archive_Tar through 1.4.10 allows an unserialization attack because phar: is blocked but PHAR: is not blocked.

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.
