perl-Data-Dumper: deep recursion stack overflow
Published Sep 30, 2014
2.1
LOWCVSS 2.0
EPSS 0.55%
Description
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.
