The Dumper method in Data::Dumper before 2.154, as used in Perl 5.20.1
and earlier, allows context-dependent attackers to cause a denial of
service (stack consumption and crash) via an Array-Reference with many
nested Array-References, which triggers a large number of recursive
calls to the DD_dump function.
Note:References are provided for the convenience of the reader to help distinguish between vulnerabilities. The list is not intended to be complete.
