Synopsis :

The remote openSUSE host is missing a security update.

Description :

perl-YAML-LibYAML was updated to version 0.59 to fix four security

These security issues were fixed :

- CVE-2013-6393: The yaml_parser_scan_tag_uri function in
scanner.c in LibYAML before 0.1.5 performs 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 triggers a heap-based buffer overflow (bnc#860617,

- CVE-2012-1152: Multiple format string vulnerabilities in
the error reporting functionality in the YAML::LibYAML
(aka YAML-LibYAML and perl-YAML-LibYAML) module 0.38 for
Perl allowed remote attackers to cause a denial of
service (process crash) via format string specifiers in
a (1) YAML stream to the Load function, (2) YAML node to
the load_node function, (3) YAML mapping to the
load_mapping function, or (4) YAML sequence to the
load_sequence function (bnc#751503).

- 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,
