Description Jan Lieskovsky 2012-03-09 10:24:03 UTC
Multiple format string flaws were found in the way perl-YAML-LibYAML, Perl YAML serialization using XS and libyaml, performed:
1) error reporting by loading of general YAML stream,
2) error reporting by loading of YAML node,
3) error reporting by loading of YAML mapping into a Perl hash, and
4) error reporting by loading of YAML sequence into a Perl array.

A remote attacker could provide a specially-crafted YAML document, which once processed by the perl-YAML-LibYAML interface would lead to perl-YAML-LibYAML based process crash.
