  script_tag(name:"insight", value:"perl-YAML-LibYAML was updated to fix three security issues.
These security issues were fixed:
- CVE-2013-6393: The yaml_parser_scan_tag_uri function in scanner.c in
 LibYAML before 0.1.5 performed an incorrect cast, which allowed remote
 attackers to cause a denial of service (application crash) and possibly
 execute arbitrary code via crafted tags in a YAML document, which
 triggered a heap-based buffer overflow (bnc#860617, bnc#911782).
- CVE-2014-9130: scanner.c in LibYAML 0.1.5 and 0.1.6, as used in the
 YAML-LibYAML (aka YAML-XS) module for Perl, allowed context-dependent
 attackers to cause a denial of service (assertion failure and crash) via
 vectors involving line-wrapping (bnc#907809, bnc#911782).
- CVE-2014-2525: Heap-based buffer overflow in the
 yaml_parser_scan_uri_escapes function in LibYAML before 0.1.6 allowed
 context-dependent attackers to execute arbitrary code via a long
 sequence of percent-encoded characters in a URI in a YAML file
 (bnc#868944, bnc#911782).");
