patch from upstream
libyaml is shipped as part of Red Hat Software Collections 1 via ruby193-libyaml package. This package is used by ruby193-ruby. Impact for this use case is limited, as ruby YAML module is unsafe for use on untrusted yaml input: http://ruby-doc.org/stdlib-1.9.3/libdoc/yaml/rdoc/YAML.html#module-YAML-label-Security Alternative SafeYAML modules which provide safe ways to load yaml input files in ruby is not provided as part of Red Hat Software Collections 1. https://github.com/dtao/safe_yaml This issue is public now: http://www.ocert.org/advisories/ocert-2014-003.html Created libyaml tracking bugs for this issue: Affects: fedora-all [bug 1081281] Debian released http://www.debian.org/security/2014/dsa-2885 to fix this issue in their libyaml-libyaml-perl package. perl-YAML-LibYAML for Fedora and EPEL look to embed libyaml too, and it seems to get built (http://kojipkgs.fedoraproject.org//packages/perl-YAML-LibYAML/0.41/3.fc20/data/logs/x86_64/build.log), but I have not checked if it actually uses the embedded copy or not. I am going to file tracking bugs regardless. Created perl-YAML-LibYAML tracking bugs for this issue: Affects: fedora-all [bug 1081382] Affects: epel-6 [bug 1081383] Can you please create a tracking bug for epel-all as well? Created libyaml tracking bugs for this issue: Affects: epel-all [bug 1081856] (In reply to John Eckersberg from comment #22) > Can you please create a tracking bug for epel-all as well? Done.
