NAME

6       perl5163delta - what is new for perl v5.16.3
7

DESCRIPTION

9       This document describes differences between the 5.16.2 release and the
10       5.16.3 release.
11
12       If you are upgrading from an earlier release such as 5.16.1, first read
13       perl5162delta, which describes differences between 5.16.1 and 5.16.2.
14

Core Enhancements

16       No changes since 5.16.0.
17

Security

19       This release contains one major and a number of minor security fixes.
20       These latter are included mainly to allow the test suite to pass
21       cleanly with the clang compiler's address sanitizer facility.
22
23   CVE-2013-1667: memory exhaustion with arbitrary hash keys
24       With a carefully crafted set of hash keys (for example arguments on a
25       URL), it is possible to cause a hash to consume a large amount of
26       memory and CPU, and thus possibly to achieve a Denial-of-Service.
27
28       This problem has been fixed.
29
30   wrap-around with IO on long strings
31       Reading or writing strings greater than 2**31 bytes in size could
32       segfault due to integer wraparound.
33
34       This problem has been fixed.
35
36   memory leak in Encode
37       The UTF-8 encoding implementation in Encode.xs had a memory leak which
38       has been fixed.
39

Acknowledgements

60       Perl 5.16.3 represents approximately 4 months of development since Perl
61       5.16.2 and contains approximately 870 lines of changes across 39 files
62       from 7 authors.
63
64       Perl continues to flourish into its third decade thanks to a vibrant
65       community of users and developers. The following people are known to
66       have contributed the improvements that became Perl 5.16.3:
67
68       Andy Dougherty, Chris 'BinGOs' Williams, Dave Rolsky, David Mitchell,
69       Michael Schroeder, Ricardo Signes, Yves Orton.

71       The list above is almost certainly incomplete as it is automatically
72       generated from version control history. In particular, it does not
73       include the names of the (very much appreciated) contributors who
74       reported issues to the Perl bug tracker.
75
76       For a more complete list of all of Perl's historical contributors,

Reporting Bugs

80       If you find what you think is a bug, you might check the articles
81       recently posted to the comp.lang.perl.misc newsgroup and the perl bug
82       database at http://rt.perl.org/perlbug/ .  There may also be
83       information at http://www.perl.org/ , the Perl Home Page.
84
85       If you believe you have an unreported bug, please run the perlbug
86       program included with your release.  Be sure to trim your bug down to a
87       tiny but sufficient test case.  Your bug report, along with the output
88       of "perl -V", will be sent off to perlbug@perl.org to be analysed by
89       the Perl porting team.
90
91       If the bug you are reporting has security implications, which make it
92       inappropriate to send to a publicly archived mailing list, then please
93       send it to perl5-security-report@perl.org. This points to a closed
94       subscription unarchived mailing list, which includes all the core
95       committers, who will be able to help assess the impact of issues,
96       figure out a resolution, and help co-ordinate the release of patches to
97       mitigate or fix the problem across all platforms on which Perl is
98       supported. Please only use this address for security issues in the Perl
99       core, not for modules independently distributed on CPAN.
