What is new for perl v5.16.3
Overview
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 perl5162delta, which describes differences between 5.16.1 and 5.16.2.
Core Enhancements
No changes since 5.16.0.
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.
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.
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.
memory leak in Encode
The UTF-8 encoding implementation in Encode.xs had a memory leak which has been fixed.
Incompatible Changes
There are no changes intentionally incompatible with 5.16.0. If any exist, they are bugs and reports are welcome.
Deprecations
There have been no deprecations since 5.16.0.
