Fedora 26: 2017-89492f7161 Critical: Perl Buffer Overflow Issues

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.

Perl utils like "splain" or "perlbug" can be found in perl-utils package.
