Hello Kurt, Steve, vendors, Case #1: ======== Two format string flaws were found in the way perl-DBD-Pg, a Perl language PostgreSQL DBI implementation, performed: 1) turning of database notices into appropriate Perl language warning messages, 2) preparation of particular DBD statement. A rogue server could provide a specially-crafted database warning or specially-crafted DBD statement, which once processed by the perl-DBD-Pg interface would lead to perl-DBD-Pg based process crash.

Case #2: ======== 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.
