Descriptions
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.
Archive_Tar versiones hasta 1.4.10, presenta una desinfección del nombre de archivo :// solo para abordar los ataques phar y, por lo tanto, cualquier otro ataque de empaquetado de flujo (tal y como file:// para sobrescribir archivos) aún puede tener éxito
A flaw was found in the Archive_Tar package. PEAR Archive_Tar could allow a local authenticated attacker to bypass security restrictions caused by a stream-wrapper attack. An attacker can overwrite arbitrary files on the system using a specially-crafted tar archive.
PEAR Archive_Tar allows an unserialization attack because phar: is blocked but PHAR: is not blocked. PEAR stands for PHP Extension and Application Repository and it is an open-source framework and distribution system for reusable PHP components with known usage in third-party products such as Drupal Core and Red Hat Linux.
