Announcement ID: openSUSE-SU-2016:1067-1
Rating: moderate
References: #860617 #868944 #907809 #911782
Cross-References: CVE-2013-6393 CVE-2014-2525 CVE-2014-9130

Affected Products:
openSUSE Leap 42.1
______________________________________________________________________________

An update that solves three vulnerabilities and has one
errata is now available.

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, bnc#911782).

This update was imported from the SUSE:SLE-12:Update update project.
