The remote Amazon Linux AMI host is missing a security update.
The yaml_parser_scan_tag_uri function in scanner.c in LibYAML before
0.1.5 performs an incorrect cast, which allows remote attackers to
cause a denial of service (application crash) and possibly execute
arbitrary code via crafted tags in a YAML document, which triggers a
heap-based buffer overflow.
