| CVE-2020-36401 | ALTO7.8 | mruby 2.1.2 has a double free in mrb_default_allocf (called from mrb_free and obj_free). | 01/07/2021 |
| CVE-2020-15866 | CRÍTICO9.8 | mruby through 2.1.2-rc has a heap-based buffer overflow in the mrb_yield_with_class function in vm.c because of incorrect VM stack handling. It can be triggered via the stack_copy function. | 21/07/2020 |
| CVE-2020-6840 | CRÍTICO9.8 | In mruby 2.1.0, there is a use-after-free in hash_slice in mrbgems/mruby-hash-ext/src/hash-ext.c. | 11/01/2020 |
| CVE-2020-6839 | CRÍTICO9.8 | In mruby 2.1.0, there is a stack-based buffer overflow in mrb_str_len_to_dbl in string.c. | 11/01/2020 |
| CVE-2020-6838 | CRÍTICO9.8 | In mruby 2.1.0, there is a use-after-free in hash_values_at in mrbgems/mruby-hash-ext/src/hash-ext.c. | 11/01/2020 |
| CVE-2018-14337 | ALTO7.5 | The CHECK macro in mrbgems/mruby-sprintf/src/sprintf.c in mruby 1.4.1 contains a signed integer overflow, possibly leading to out-of-bounds memory access because the mrb_str_resize function in string.c does not check for a negative length. | 17/07/2018 |
| CVE-2018-12249 | ALTO7.5 | An issue was discovered in mruby 1.4.1. There is a NULL pointer dereference in mrb_class_real because "class BasicObject" is not properly supported in class.c. | 12/06/2018 |
| CVE-2018-12248 | ALTO7.5 | 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. | 12/06/2018 |
| CVE-2018-12247 | ALTO7.5 | 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). | 12/06/2018 |
| CVE-2018-11743 | CRÍTICO9.8 | 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. | 05/06/2018 |
| CVE-2018-10199 | CRÍTICO9.8 | 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. | 18/04/2018 |
