CVE-2014-4330

Status Candidate

Overview

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.

Ubuntu Security Notice USN-2916-1
Posted Mar 3, 2016
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 2916-1 - It was discovered that Perl incorrectly handled certain regular expressions with an invalid backreference. An attacker could use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. Markus Vervier discovered that Perl incorrectly handled nesting in the Data::Dumper module. An attacker could use this issue to cause Perl to consume memory and crash, resulting in a denial of service. Various other issues were also addressed.

Mandriva Linux Security Advisory 2015-136

Mandriva Linux Security Advisory 2015-136 - 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 via an Array-Reference with many nested Array-References, which triggers a large number of recursive calls to the DD_dump function. Also, the Text::Wrap version provided in perl contains a bug that can lead to a code path that shouldn't be hit. This can lead to crashes in other software, such as Bugzilla. The Text::Wrap module bundled with Perl has been patched and the Data::Dumper module bundled with Perl has been updated to fix these issues.

Perl 5.20.1 Deep Recursion Stack Overflow
Posted Sep 25, 2014
Authored by Markus Vervier | Site lsexperts.de

A stack overflow was discovered when serializing data via the Data::Dumper extension which is part of Perl-Core. By using the "Dumper" method on a large Array-Reference which recursively contains other Array-References, it is possible to cause many recursive calls to the DD_dump native function and ultimately exhaust all available stack memory.
