From c7fa2bf56820dc06c6771852380d5d3fe6157896 Mon Sep 17 00:00:00 2001 From: yui-knk Date: Fri, 15 Sep 2017 00:40:38 +0000 Subject: ext/coverage/coverage.c (rb_coverage_start): Ensure `opt` is a hash Ensure `opt` is a hash before using `rb_hash_lookup` to `opt`. This will prevent SEGV when an inappropriate object (i.e. an array) is passed to `opt`. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@59915 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- ext/coverage/coverage.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'ext/coverage') diff --git a/ext/coverage/coverage.c b/ext/coverage/coverage.c index cb70b33af9..c2ccd343d0 100644 --- a/ext/coverage/coverage.c +++ b/ext/coverage/coverage.c @@ -42,6 +42,8 @@ rb_coverage_start(int argc, VALUE *argv, VALUE klass) } else { mode = 0; + opt = rb_convert_type(opt, T_HASH, "Hash", "to_hash"); + if (RTEST(rb_hash_lookup(opt, ID2SYM(rb_intern("lines"))))) mode |= COVERAGE_TARGET_LINES; if (RTEST(rb_hash_lookup(opt, ID2SYM(rb_intern("branches"))))) -- cgit v1.2.3
