9 This document describes differences between the 5.16.2 release and the
10 5.16.3 release.

14
16 No changes since 5.16.0.
17
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 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 This problem has been fixed.
29 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 This problem has been fixed.
35 memory leak in Encode
37 The UTF-8 encoding implementation in Encode.xs had a memory leak which
38 has been fixed.
39
41 There are no changes intentionally incompatible with 5.16.0. If any
42 exist, they are bugs and reports are welcome.
43
45 There have been no deprecations since 5.16.0.
46

61 5.16.2 and contains approximately 870 lines of changes across 39 files
62 from 7 authors.
63 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 Andy Dougherty, Chris 'BinGOs' Williams, Dave Rolsky, David Mitchell,
69 Michael Schroeder, Ricardo Signes, Yves Orton.
70 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 For a more complete list of all of Perl's historical contributors,
77 please see the AUTHORS file in the Perl source distribution.

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 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 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.
