| CVE-2018-12248 | Hig | 0.00 | 7.5 | 0.02 | Jun 12, 2018 | An issue was discovered in mruby 1.4.1. There is a heap-based buffer over-read associated with OP_ENTER because mrbgems/mruby-fiber/src/fiber.c does not extend the stack in cases of many arguments to fiber. | ||
| CVE-2018-12247 | Hig | 0.00 | 7.5 | 0.02 | Jun 12, 2018 | An issue was discovered in mruby 1.4.1. There is a NULL pointer dereference in mrb_class, related to certain .clone usage, because mrb_obj_clone in kernel.c copies flags other than the MRB_FLAG_IS_FROZEN flag (e.g., the embedded flag). | ||
| CVE-2018-11743 | Cri | 0.00 | 9.8 | 0.02 | Jun 5, 2018 | The init_copy function in kernel.c in mruby 1.4.1 makes initialize_copy calls for TT_ICLASS objects, which allows attackers to cause a denial of service (mrb_hash_keys uninitialized pointer and application crash) or possibly have unspecified other impact. | ||
| CVE-2018-10199 | Cri | 0.00 | 9.8 | 0.02 | Apr 18, 2018 | In versions of mruby up to and including 1.4.0, a use-after-free vulnerability exists in src/io.c::File#initilialize_copy(). An attacker that can cause Ruby code to be run can possibly use this to execute arbitrary code. | ||
| CVE-2018-10191 | Cri | 0.00 | 9.8 | 0.03 | Apr 17, 2018 | In versions of mruby up to and including 1.4.0, an integer overflow exists in src/vm.c::mrb_vm_exec() when handling OP_GETUPVAR in the presence of deep scope nesting, resulting in a use-after-free. An attacker that can cause Ruby code to be run can use this to possibly execute… |
