The SingleDocParser::HandleFlowSequence function in yaml-cpp (aka LibYaml-C++) 0.6.2 allows remote attackers to cause a denial of service (stack consumption and application crash) via a crafted YAML file.
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
