Source   Latest Release: perl-5.21.2

NAME ^

perl5142delta - what is new for perl v5.14.2

DESCRIPTION ^

This document describes differences between the 5.14.1 release and the 5.14.2 release.

If you are upgrading from an earlier release such as 5.14.0, first read perl5141delta, which describes differences between 5.14.0 and 5.14.1.

Core Enhancements ^

No changes since 5.14.0.

Security ^

File::Glob::bsd_glob() memory error with GLOB_ALTDIRFUNC (CVE-2011-2728).

Calling File::Glob::bsd_glob with the unsupported flag GLOB_ALTDIRFUNC would cause an access violation / segfault. A Perl program that accepts a flags value from an external source could expose itself to denial of service or arbitrary code execution attacks. There are no known exploits in the wild. The problem has been corrected by explicitly disabling all unsupported flags and setting unused function pointers to null. Bug reported by Clément Lecigne.

Encode decode_xs n-byte heap-overflow (CVE-2011-2939)

A bug in Encode could, on certain inputs, cause the heap to overflow. This problem has been corrected. Bug reported by Robert Zacek.

Incompatible Changes ^

There are no changes intentionally incompatible with 5.14.0. If any exist, they are bugs and reports are welcome.

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 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.
