CVE-2017-16229
In the Ox gem 2.8.1 for Ruby, the process crashes with a stack-based buffer over-read in the read_from_str function in sax_buf.c when a crafted input is supplied to sax_parse.
Does this matter?
Lower severity and a low EPSS score (0.97%). Track it; it rarely justifies an emergency change on its own.
