Detailsinfo

A vulnerability was found in Ruby up to 2.1 (Programming Language Software). It has been declared as very critical. This vulnerability affects an unknown part of the component String Conversion Floating Point Number Parsing Heap. The manipulation with an unknown input leads to a memory corruption vulnerability. The CWE definition for the vulnerability is CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

Heap-based buffer overflow in Ruby 1.8, 1.9 before 1.9.3-p484, 2.0 before 2.0.0-p353, 2.1 before 2.1.0 preview2, and trunk before revision 43780 allows context-dependent attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a string that is converted to a floating point value, as demonstrated using (1) the to_f method or (2) JSON.parse.

The weakness was released 11/22/2013 by Charlie Somerville (Alexander) as confirmed advisory (Website). The advisory is available at ruby-lang.org. The public release was coordinated with the vendor.
