Description

ConfBridge in Asterisk 11.x before 11.14.1 and Certified Asterisk 11.6 before 11.6-cert8 does not properly handle state changes, which allows remote attackers to cause a denial of service (channel hang and memory consumption) by causing transitions to be delayed, which triggers a state change from hung up to waiting for media.

Affected products

Digium Asterisk: through 11.14.0
Digium Certified Asterisk: 11.6-cert1, 11.6-cert2, 11.6-cert3, 11.6-cert4, 11.6-cert5, 11.6-cert6 (+2)
