Perl Improper Restriction of Operations within the Bounds of a Memory Buffer Vulnerability - CVE-2014-4330
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.
