Digest unsafe use of eval (CVE-2011-3597)
perl5143delta - what is new for perl v5.14.3
This document describes differences between the 5.14.2 release and the 5.14.3 release.
If you are upgrading from an earlier release such as 5.12.0, first read the perl5140delta manpage, which describes differences between 5.12.0 and 5.14.0.
No changes since 5.14.0.
Digest unsafe use of eval (CVE-2011-3597)The Digest->new() function did not properly sanitize input before
using it in an eval() call, which could lead to the injection of arbitrary
Perl code.
In order to exploit this flaw, the attacker would need to be able to set the algorithm name used, or be able to execute arbitrary Perl code already.
This problem has been fixed.
Poorly written perl code that allows an attacker to specify the count to perl's 'x' string repeat operator can already cause a memory exhaustion denial-of-service attack. A flaw in versions of perl before 5.15.5 can escalate that into a heap buffer overrun; coupled with versions of glibc before 2.16, it possibly allows the execution of arbitrary code.
This problem has been fixed.
There are no changes intentionally incompatible with 5.14.0. If any exist, they are bugs and reports are welcome.
There have been no deprecations since 5.14.0.

IPC::Open3::open3($in, $out, $err, '-').
[perl #95748]
the Digest manpage has been upgraded from version 1.16 to 1.16_01.
See Security.
the Module::CoreList manpage has been updated to version 2.49_04 to add data for this release.

The system gcc (rather than any other gcc which might be in the compiling
user's path) is now used when searching for libraries such as -lm.
LFS support was enabled in GNU/Hurd.
/i
regular expression matching, in which a match improperly fails if the
pattern is in UTF-8, the target string is not, and a Latin-1 character
precedes a character in the string that should match the pattern. [perl
#101710]
In case-insensitive regular expression pattern matching, no longer on
UTF-8 encoded strings does the scan for the start of match only look at
the first possible position. This caused matches such as
"f\x{FB00}" =~ /ff/i to fail.
The sitecustomize support was made relocatableinc aware, so that
-Dusesitecustomize and -Duserelocatableinc may be used together.
The smartmatch operator (~~) was changed so that the right-hand side
takes precedence during Any ~~ Object operations.
A bug has been fixed in the tainting support, in which an index()
operation on a tainted constant would cause all other constants to become
tainted. [perl #64804]
A regression has been fixed that was introduced in perl 5.12, whereby
tainting errors were not correctly propagated through die().
[perl #111654]
A regression has been fixed that was introduced in perl 5.14, in which
/[[:lower:]]/i and /[[:upper:]]/i no longer matched the opposite case.

Perl 5.14.3 represents approximately 12 months of development since Perl 5.14.2 and contains approximately 2,300 lines of changes across 64 files from 22 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 5.14.3:
Abigail, Andy Dougherty, Carl Hayter, Chris 'BinGOs' Williams, Dave Rolsky, David Mitchell, Dominic Hargreaves, Father Chrysostomos, Florian Ragwitz, H.Merijn Brand, Jilles Tjoelker, Karl Williamson, Leon Timmermans, Michael G Schwern, Nicholas Clark, Niko Tyni, Pino Toscano, Ricardo Signes, Salvador Fandiño, Samuel Thibault, Steve Hay, Tony Cook.
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.
Many of the changes included in this version originated in the CPAN modules included in Perl's core. We're grateful to the entire CPAN community for helping Perl to flourish.
For a more complete list of all of Perl's historical contributors, please see the AUTHORS file in the Perl source distribution.
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 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 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 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.
