=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.

=head1 Acknowledgements
|
|
|
|
Perl 5.16.3 represents approximately 4 months of development since Perl 5.16.2
|
|
and contains approximately 870 lines of changes across 39 files from 7 authors.
|
|
|
|
Perl continues to flourish into its third decade thanks to a vibrant community
|
|
of users and developers. The following people are known to have contributed the
|
|
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 perlbug@perl.org 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 perl5-security-report@perl.org. 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.
