Description

The yaml_parser_scan_tag_uri function in scanner.c in LibYAML before 0.1.5 performs an incorrect cast, which allows 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.

Affected configurations

• pyyaml libyaml (<= 0.1.4) • pyyaml libyaml 0.0.1 • pyyaml libyaml 0.1.1 • pyyaml libyaml 0.1.2 • pyyaml libyaml 0.1.3 • canonical ubuntu linux 12.04 • canonical ubuntu linux 12.10 • canonical ubuntu linux 13.10 • redhat openstack 3.0 • redhat openstack 4.0 • debian debian linux 6.0 • debian debian linux 7.0 • opensuse leap 42.1 • opensuse opensuse 11.4 • opensuse opensuse 13.1 • opensuse opensuse 13.2
