CVE-2013-6393

CVSS v2.0

6.8

Medium

VectorAV:N/AC:M/Au:N/C:P/I:P/A:P
Name of the Vulnerable Software and Affected Versions LibYAML versions prior to 0.1.5
Description The issue is related to an incorrect cast in the yaml parser scan tag uri function, which can lead to a denial of service (application crash) and possibly allow remote attackers to execute arbitrary code via crafted tags in a YAML document, triggering a heap-based buffer overflow. Multiple vulnerabilities in the libyaml package may compromise the confidentiality, integrity, and availability of protected information, and exploitation can be done remotely.
Recommendations
  • Update to version 0.1.5 or later, which includes a fix for the heap-based buffer overflow vulnerability.
  • For versions 0.2.2 and earlier that depend on native libyaml version 0.1.5 or earlier, update to version 0.2.3 that includes a version of LibYAML with the fix.
