SUSE SLED12 / SLES12 Security Update : perl-YAML-LibYAML (SUSE-SU-2015:0953-2)

This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.

Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

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,
