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.
Heap-based buffer overflow in the yaml_parser_scan_uri_escapes
function in LibYAML before 0.1.6 allows context-dependent attackers to
execute arbitrary code via a long sequence of percent-encoded
characters in a URI in a YAML file.
