=head1 NAME | |
perl5163delta - what is new for perl v5.16.3 | |
=head1 DESCRIPTION | |
This document describes differences between the 5.16.2 release and | |
the 5.16.3 release. | |
If you are upgrading from an earlier release such as 5.16.1, first read | |
L<perl5162delta>, which describes differences between 5.16.1 and | |
5.16.2. | |
=head1 Core Enhancements | |
No changes since 5.16.0. | |
=head1 Security | |
This release contains one major and a number of minor security fixes. | |
These latter are included mainly to allow the test suite to pass cleanly | |
with the clang compiler's address sanitizer facility. | |
=head2 CVE-2013-1667: memory exhaustion with arbitrary hash keys | |
With a carefully crafted set of hash keys (for example arguments on a | |
URL), it is possible to cause a hash to consume a large amount of memory | |
and CPU, and thus possibly to achieve a Denial-of-Service. | |
This problem has been fixed. | |
=head2 wrap-around with IO on long strings | |
Reading or writing strings greater than 2**31 bytes in size could segfault | |
due to integer wraparound. | |
This problem has been fixed. | |
=head2 memory leak in Encode | |
The UTF-8 encoding implementation in Encode.xs had a memory leak which has been | |
fixed. | |
=head1 Incompatible Changes | |
There are no changes intentionally incompatible with 5.16.0. If any | |
exist, they are bugs and reports are welcome. | |
=head1 Deprecations | |
There have been no deprecations since 5.16.0. | |

improvements that became Perl 5.16.3: | |
Andy Dougherty, Chris 'BinGOs' Williams, Dave Rolsky, David Mitchell, Michael | |
Schroeder, Ricardo Signes, Yves Orton. | |
The list above is almost certainly incomplete as it is automatically generated | |
from version control history. In particular, it does not include the names of | |
the (very much appreciated) contributors who reported issues to the Perl bug | |
tracker. | |
For a more complete list of all of Perl's historical contributors, please see | |
the F<AUTHORS> file in the Perl source distribution. | |
=head1 Reporting Bugs | |
If you find what you think is a bug, you might check the articles | |
recently posted to the comp.lang.perl.misc newsgroup and the perl | |
bug database at http://rt.perl.org/perlbug/ . There may also be | |
information at http://www.perl.org/ , the Perl Home Page. | |
If you believe you have an unreported bug, please run the L<perlbug> | |
program included with your release. Be sure to trim your bug down | |
to a tiny but sufficient test case. Your bug report, along with the | |
output of C<perl -V>, will be sent off to [email protected] to be | |
analysed by the Perl porting team. | |
If the bug you are reporting has security implications, which make it | |
inappropriate to send to a publicly archived mailing list, then please | |
send it to [email protected]. This points to a closed | |
subscription unarchived mailing list, which includes all the core | |
committers, who will be able to help assess the impact of issues, figure | |
out a resolution, and help co-ordinate the release of patches to | |
mitigate or fix the problem across all platforms on which Perl is | |
supported. Please only use this address for security issues in the Perl | |
core, not for modules independently distributed on CPAN. | |
