📄 Description (English)

PEAR Archive_Tar Improper Link Resolution Vulnerability — PEAR Archive_Tar Tar.php allows write operations with directory traversal due to inadequate checking of symbolic links. 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.

🤖 AI Executive Summary
