Descriptions

(1) DL and (2) Fiddle in Ruby 1.9 before 1.9.3 patchlevel 426, and 2.0 before 2.0.0 patchlevel 195, do not perform taint checking for native functions, which allows context-dependent attackers to bypass intended $SAFE level restrictions.

(1) DL y (2) Fiddle en Ruby 1.9 anterior a 1.9.3 patchlevel 426, y 2.0 anterior a 2.0.0 patchlevel 195, no se realizan la comprobación de corrupción de las funciones nativas, lo que permite a atacantes dependientes de contexto eludir el nivel de restricciones $SAFE.

Charlie Somerville discovered that Ruby incorrectly handled floating point number conversion. An attacker could possibly use this issue with an application that converts text to floating point numbers to cause the application to crash, resulting in a denial of service, or possibly execute arbitrary code. Vit Ondruch discovered that Ruby did not perform taint checking for certain functions. An attacker could possibly use this issue to bypass certain intended restrictions. Various other issues were also addressed.
