perl5143delta (1) Linux Manual Page
NAME
perl5143delta – what is new for perl v5.14.3
DESCRIPTION
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 perl5140delta, which describes differences between 5.12.0 and 5.14.0.
Core Enhancements
No changes since 5.14.0.
Security
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.
Heap buffer overrun in ‘x’ string repeat operator (CVE-2012-5195)
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.
Incompatible Changes
There are no changes intentionally incompatible with 5.14.0. If any exist, they are bugs and reports are welcome.
Deprecations
There have been no deprecations since 5.14.0.

Platform-Specific Notes
- FreeBSD
- The FreeBSD hints file was corrected to be compatible with FreeBSD 10.0.
- Solaris and NetBSD
- Configure was updated for “procselfexe” support on Solaris and NetBSD.
- HP-UX
- README.hpux was updated to note the existence of a broken header in HP-UX 11.00.
- Linux
- libutil is no longer used when compiling on Linux platforms, which avoids warnings being emitted.
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".
- Mac OS X
- The locale tests were updated to reflect the behaviour of locales in Mountain Lion.
- GNU/Hurd
- Various build and test fixes were included for GNU/Hurd.
LFS support was enabled in GNU/Hurd.
- NetBSD
- The NetBSD hints file was corrected to be compatible with NetBSD 6.*
Bug Fixes
- •
- A regression has been fixed that was introduced in 5.14, in "/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
