CVE-2015-2313
Sandstorm Cap'n Proto CPU Consumption Denial of Service
Description
Sandstorm Cap'n Proto before 0.4.1.1 and 0.5.x before 0.5.1.2, when an application invokes the totalSize method on an object reader, allows remote peers to cause a denial of service (CPU consumption) via a crafted small message, which triggers a "tight" for loop.
