CVE-2008-2663 ruby: Integer overflows in rb_ary_store()
Last modified: 2016-03-04 07:12:44 EST
Drew Yao of the Apple Product Security team reported an integer overflow leading
to a memory mis-allocation and heap overflow in the rb_ary_store() function
used by ruby interpreter for handling arrays. This can be used to crash and
possibly execute arbitrary code with the privileges of Ruby application which
use untrusted input in array operations.
Red Hat would like to thank Drew Yao of the Apple Product Security team for reporting this issue.
