HAProxy contains a flaw that may allow a remote denial of service. The issue is due to an uninitialized field in the struct session. This can conceivably be triggered when a session is freed (e.g., an attacker could create numerous sessions to increase the chance of crash), and may result in loss of availability for the service.
