A NULL pointer dereference vulnerability exists in the Prism parser component of mruby 4.0.0. An attacker can provide a specially crafted Ruby source file that triggers the parser to pass a NULL pointer to nonnull string handling functions, resulting in undefined behavior and application crash.
A flaw has been found in mruby up to 3.4.0. This affects the function mrb_vm_exec of the file src/vm.c of the component JMPNOT-to-JMPIF Optimization. Executing a manipulation can lead to use after free. The attack needs to be launched locally. The exploit has been published and may be used. This patch is called e50f15c1c6e131fa7934355eb02b8173b13df415. It is advisable to implement a patch to correct this issue.
A vulnerability has been found in mruby up to 3.4.0. This vulnerability affects the function sort_cmp of the file src/array.c. Such manipulation leads to use after free. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. The name of the patch is eb398971bfb43c38db3e04528b68ac9a7ce509bc. It is advisable to implement a patch to correct this issue.
A vulnerability, which was classified as problematic, was found in mruby up to 3.4.0-rc2. Affected is the function scope_new of the file mrbgems/mruby-compiler/core/codegen.c of the component nregs Handler. The manipulation leads to heap-based buffer overflow. An attack has to be approached locally. The exploit has been disclosed to the public and may be used. The name of the patch is 1fdd96104180cc0fb5d3cb086b05ab6458911bb9. It is recommended to apply a patch to fix this issue.
An Untrusted Pointer Dereference was discovered in function mrb_vm_exec in mruby before 3.1.0-rc. The vulnerability causes a segmentation fault and application crash.
Out-of-bounds Read in mrb_obj_is_kind_of in in GitHub repository mruby/mruby prior to 3.2. # Impact: Possible arbitrary code execution if being exploited.
heap-buffer-overflow in mrb_vm_exec in mruby/mruby in GitHub repository mruby/mruby prior to 3.2. Possible arbitrary code execution if being exploited.
Use-After-Free in str_escape in mruby/mruby in GitHub repository mruby/mruby prior to 3.2. Possible arbitrary code execution if being exploited.
NULL Pointer Dereference in mrb_vm_exec with super in GitHub repository mruby/mruby prior to 3.2. This vulnerability is capable of making the mruby interpreter crash, thus affecting the availability of the system.
User after free in mrb_vm_exec in GitHub repository mruby/mruby prior to 3.2.
NULL Pointer Dereference in GitHub repository mruby/mruby prior to 3.2.
NULL Pointer Dereference in Homebrew mruby prior to 3.2.
mruby is vulnerable to NULL Pointer Dereference
An untrusted pointer dereference in mrb_vm_exec() of mruby v3.0.0 can lead to a segmentation fault or application crash.
mruby is vulnerable to Heap-based Buffer Overflow
mruby is vulnerable to NULL Pointer Dereference
mruby 2.1.2 has a double free in mrb_default_allocf (called from mrb_free and obj_free).
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.
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.
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.
