CVE-2014-4330

Updated perl package fixes security vulnerability:

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 (CVE-2014-4330).

The Data::Dumper module bundled with Perl has been updated to fix these issues.

Updated perl package fixes security vulnerability:

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 (CVE-2014-4330).

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.

Updated perl-Data-Dumper package fixes security vulnerability:

The Dumper method in Data::Dumper before 2.154, 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 (CVE-2014-4330).

This update fixes a memory leak and an infinite recursion in Data::Dumper. (CVE-2014-4330)

Security Issues:

* CVE-2014-4330
  <http://cve.mitre.org/cgi-bin/cvename.cgi?name=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.

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. (CVE-2013-7422)

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. (CVE-2014-4330)

Stephane Chazelas discovered that Perl incorrectly handled duplicate environment variables. An attacker could possibly use this issue to bypass the taint protection mechanism. (CVE-2016-2381)
