Name of the Vulnerable Software and Affected Versions yaml-cpp version 0.6.2
Description The issue allows remote attackers to cause a denial of service, resulting in stack consumption and application crash, via a crafted YAML file. This is due to a problem in the Scanner::EnsureTokensInQueue function.
Recommendations For yaml-cpp version 0.6.2, consider avoiding the use of the Scanner::EnsureTokensInQueue function until a patch is available. As a temporary workaround, restrict the processing of crafted YAML files to minimize the risk of exploitation.
