Fedora 30: FEDORA-2019-1911b73cee Moderate: perl-YAML Typeglobs Issue

fedora
Calendar Grey May 7, 2019
Dist Fedora Esm H88
The latest security patch for Fedora's perl-YAML mandates that $LoadCode needs to be explicitly turned on to mitigate risks from typeglob manipulations.
This update enforces that $LoadCode must be enabled to use the feature of evaluating typeglobs, because with the typeglob feature you would be able to set the variable $YAML::LoadC...

Summary

The YAML.pm module implements a YAML Loader and Dumper based on the YAML 1.0

specification (https://yaml.org/spec/). YAML is a generic data serialization

language that is optimized for human readability. It can be used to express the

data structures of most modern programming languages, including Perl. For

information on the YAML syntax, please refer to the YAML specification.

This update enforces that $LoadCode must be enabled to use the feature of

evaluating typeglobs, because with the typeglob feature you would be able to set

the variable $YAML::LoadCode from a YAML file, and that would be a security

issue.

* Sun Apr 28 2019 Paul Howarth - 1.28-1

- Update to 1.28

- Security fix: only enable loading globs when $LoadCode is set (GH#213)

- Modernize spec using %{make_build} and %{make_install}
