medium Nessus Plugin ID 83869
Language:
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, bnc#911782).
Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
