Fedora 28: FEDORA-2018-d1ba58394e Critical: Perl Heap Overflow

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.

This is a metapackage with all the Perl bits and core modules that can be

found in the upstream tarball from perl.org.

If you need only a specific feature, you can install a specific package

instead. E.g. to handle Perl scripts with /usr/bin/perl interpreter,

install perl-interpreter package. See perl-interpreter description for more

details on the Perl decomposition into packages.

This release provides Perl 5.26.2 that fixes a heap buffer overflow in the

pack() function and two overflows in regular expression engine.
