CVE-2017-11465 ruby: Invalid read/write in parser_yyerror function in UTF-8 parser
Last modified: 2017-07-31 18:37:25 EDT
The parser_yyerror function in the UTF-8 parser in Ruby 2.4.1 allows attackers to cause a denial of service (invalid write or read) or possibly have unspecified other impact via a crafted Ruby script, related to the parser_tokadd_utf8 function in parse.y. NOTE: this might have security relevance as a bypass of a $SAFE protection mechanism.
Created ruby tracking bugs for this issue:
