CVE-2014-8414: Digium Asterisk

Medium severity, CVSS 5.0. EPSS: 2.3% chance of exploitation in the next 30 days.

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: up to and including 11.14.0
• Digium Certified Asterisk: version 11.6 only; version 11.6.0 only
