| Package | Affected versions | Patched versions |
|---|---|---|
| crack | < 0.3.2 | 0.3.2 |
| crack | = 0.1.8= 0.2.0= 0.3.0≤ 0.3.1 |
The crack gem 0.3.1 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.
