extlib does not properly restrict casts of string values (GHSA-9h36-4jf2-hx53)
Published: 2017-10-24T18:33:37Z
Aliases: CVE-2013-1802
Severity: HIGH · CWE: CWE-704

The extlib gem 0.9.15 and earlier for Ruby does not properly restrict casts of string values, which might allow remote attackers to conduct object-injection attacks and execute arbitrary code, or cause a denial of service (memory and CPU consumption) by leveraging Action Pack support for (1) YAML type conversion or (2) Symbol type conversion, a similar vulnerability to CVE-2013-0156.
