HP Security Bulletin HPSBNS03635 1 - Multiple potential remote and local vulnerabilities impacting Perl and PHP have been addressed by HPE NonStop Servers OSS Script Languages. The vulnerabilities include Perl's opportunistic loading of optional modules which might allow local users to gain elevation of privilege via a Trojan horse library under the current working directory. Revision 1 of this advisory.

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 - 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.

Mandriva Linux Security Advisory 2014-199 - Updated perl and perl-Data-Dumper packages fixes security 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. The Data::Dumper module bundled with perl and the perl-Data-Dumper packages has been updated to fix this issue.

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.
