Fedora 23: perl Security Update
Summary
Perl is a high-level programming language with roots in C, sed, awk and shell
scripting. Perl is good at handling processes and files, and is especially
good at handling text. Perl's hallmarks are practicality and efficiency.
While it is used to do a lot of different things, Perl's most common
applications are system administration utilities and web programming.
Install this package if you want to program in Perl or enable your system to
handle Perl scripts with /usr/bin/perl interpreter.
If your script requires some Perl modules, you can install them with
"perl(MODULE)" where "MODULE" is a name of required module. E.g. install
"perl(Test::More)" to make Test::More Perl module available.
If you need all the Perl modules that come with upstream Perl sources, so
called core modules, install perl-core package.
If you only need perl run-time as a shared library, i.e. Perl interpreter
embedded into another application, the only essential package is perl-libs.
Perl header files can be found in perl-devel package.
Update Information:
Fix manipulating environment variables to align with how glibc handles duplicated environment variables. Perl now uses the first variable listed in the environment array and it removes any subsequent entries of the same-named variable from the array, so that child processes have only one variable instance in its environment.
