CVE-2013-6393
6.8 · MEDIUMOverview
CVE-2013-6393 is a medium-severity vulnerability affecting pyyaml libyaml. It was published on February 6, 2014 and has a CVSS 2.0 base score of 6.8 (MEDIUM).
This vulnerability has a CVSS 2.0 base score of 6.8, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from pyyaml. Update libyaml to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
