Description

Xserver contains a flaw that may lead to an unauthorized information disclosure. The issue is due to the server not properly filtering dot-dot-slash (../). By sending a specially-crafted HTTP request containing "dot dot" sequences, a remote attacker can traverse directories and view any file on the system, resulting in loss of confidentiality.
