Medium Nessus Plugin ID 71079
SynopsisThe remote Amazon Linux AMI host is missing a security update.
DescriptionHeap-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.
SolutionRun 'yum update ruby' to update your system.
