Vigil@nce - Perl: denial of service via Data-Dumper

September 2014 by Vigil@nce

This bulletin was written by Vigil@nce : http://vigilance.fr/offer

SYNTHESIS OF THE VULNERABILITY

When an attacker can provide a complex data structure to Perl
Data::Dumper(), he can thus trigger a denial of service.

Impacted products: Unix (platform)

Severity: 1/4

Creation date: 25/09/2014

DESCRIPTION OF THE VULNERABILITY

The Perl Data::Dumper() function is used to serialize data.

A Perl array, can contain a reference to a sub-array, containing a
sub-sub-array reference, etc. However, the DD_dump() function uses
a recursive call to handle this case, which leads to a stack
overflow, and stops the application.

When an attacker can provide a complex data structure to Perl
Data::Dumper(), he can thus trigger a denial of service.
