CWE-122
AllowedHeap-based Buffer Overflow
Abstraction: Variant · Status: Draft
A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc().
4106 vulnerabilities reference this CWE, most recent first.

User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of BMP images. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-15400.

GHSA-35W3-PJM6-WJ95
Vulnerability from github – Published: 2026-06-19 19:36 – Updated: 2026-06-19 19:36Summary
Oj.dump in object mode is vulnerable to a heap buffer overflow when serializing Exception objects with a large :indent value. The serializer allocates a buffer sized for the object's attributes but does not account for the indent bytes added on each write. With indent: 5000, the accumulation of 5,000-byte indent strings overflows the 13,150-byte heap allocation, corrupting adjacent heap memory.
Version
- Software: oj gem
- Affected: all versions with
ext/oj/dump.h - Latest tested: 3.17.1 (confirmed present)
Details
ext/oj/dump.h, line 75–77:
static void fill_indent(Out out, int depth) {
if (0 < out->opts->indent) {
memset(out->buf + out->cur, ' ', (size_t)(out->opts->indent * depth));
When dumping an Exception object in :object mode, dump_obj_attrs calls fill_indent repeatedly for each attribute. The buffer is pre-allocated based on the serialized content but not the indentation overhead. With indent: 5000 the indent block for a nested object exceeds the remaining buffer space, producing a heap-buffer-overflow of size 5,000 at the end of the allocated region.
ASAN report:
==101656==ERROR: AddressSanitizer: heap-buffer-overflow on address 0x527000022c5e

0x527000022c5e is located 0 bytes after 13150-byte region [0x52700001f900, 0x527000022c5e)
Reproduce
require "oj"
obj = Oj.load('{"^o":"RuntimeError"}', mode: :object)
Oj.dump(obj, mode: :object, indent: 5000)
Workarounds
This is at the discretion of the developer and not a public facing option so the workaround is the develop should not use extreme indents and should not offer the option for users to dump Ruby data with unlimited indentation size.

GHSA-3632-54Q8-M96X
Vulnerability from github – Published: 2025-09-02 17:22 – Updated: 2025-09-02 17:22The crate has the following vulnerabilities:
-
The public trait
arenavec::common::AllocHandleallows the return of raw pointers through its methodsallocateandallocate_or_extend. However, the trait is not marked as unsafe, meaning users of the crate may implement it under the assumption that the library safely handles the returned raw pointers. These raw pointers can later be dereferenced within safe APIs of the crate-such asarenavec::common::SliceVec::push-potentially leading to arbitrary memory access. -
The safe API
arenavec::common::SliceVec::reservecan reach the private functionarenavec::common::allocate_inner. Incorrect behavior inallocate_innermay result in aSliceVecwith an increased capacity, even though the underlying memory has not actually been expanded. This mismatch betweenSliceVec.capacityand the actual reserved memory can lead to a heap buffer overflow. -
The safe API
arenavec::common::SliceVec::split_offcan duplicate the ownership of the elements inself(of typeSliceVec) if they implement theDroptrait. Specifically, whenat == 0, the method returns a newSliceVecwith the same length asself. Since bothselfand the returned object point to the same heap memory, dropping one will deallocate the shared memory. When the other is subsequently dropped, it will attempt to free the same memory again, resulting in a double free violation.

"details": "The crate has the following vulnerabilities:\n\n- The public trait `arenavec::common::AllocHandle` allows the return of raw pointers through its methods `allocate` and `allocate_or_extend`. However, the trait is not marked as unsafe, meaning users of the crate may implement it under the assumption that the library safely handles the returned raw pointers. These raw pointers can later be dereferenced within safe APIs of the crate-such as `arenavec::common::SliceVec::push`-potentially leading to arbitrary memory access.\n\n- The safe API `arenavec::common::SliceVec::reserve` can reach the private function `arenavec::common::allocate_inner`. Incorrect behavior in `allocate_inner` may result in a `SliceVec` with an increased capacity, even though the underlying memory has not actually been expanded. This mismatch between `SliceVec.capacity` and the actual reserved memory can lead to a heap buffer overflow.\n\n- The safe API `arenavec::common::SliceVec::split_off` can duplicate the ownership of the elements in `self` (of type `SliceVec`) if they implement the `Drop` trait. Specifically, when `at == 0`, the method returns a new `SliceVec` with the same length as `self`. Since both `self` and the returned object point to the same heap memory, dropping one will deallocate the shared memory. When the other is subsequently dropped, it will attempt to free the same memory again, resulting in a double free violation.",

Mitigation
Pre-design: Use a language or compiler that performs automatic bounds checking.
Mitigation
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation MIT-10
Strategy: Environment Hardening
- Use automatic buffer overflow detection mechanisms that are offered by certain compilers or compiler extensions. Examples include: the Microsoft Visual Studio /GS flag, Fedora/Red Hat FORTIFY_SOURCE GCC flag, StackGuard, and ProPolice, which provide various mechanisms including canary-based detection and range/index checking.
- D3-SFCV (Stack Frame Canary Validation) from D3FEND [REF-1334] discusses canary-based detection in detail.
Mitigation MIT-11
Strategy: Environment Hardening
- Run or compile the software using features or extensions that randomly arrange the positions of a program's executable and libraries in memory. Because this makes the addresses unpredictable, it can prevent an attacker from reliably jumping to exploitable code.
- Examples include Address Space Layout Randomization (ASLR) [REF-58] [REF-60] and Position-Independent Executables (PIE) [REF-64]. Imported modules may be similarly realigned if their default memory addresses conflict with other modules, in a process known as "rebasing" (for Windows) and "prelinking" (for Linux) [REF-1332] using randomly generated addresses. ASLR for libraries cannot be used in conjunction with prelink since it would require relocating the libraries at run-time, defeating the whole purpose of prelinking.
- For more information on these techniques see D3-SAOR (Segment Address Offset Randomization) from D3FEND [REF-1335].
Mitigation
Implement and perform bounds checking on input.
Mitigation
Strategy: Libraries or Frameworks
Do not use dangerous functions such as gets. Look for their safe equivalent, which checks for the boundary.
Mitigation
Use OS-level preventative functionality. This is not a complete solution, but it provides some defense in depth.
CAPEC-92: Forced Integer Overflow
This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
