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().

Title
Electron Vulnerable to Heap Buffer Overflow in NativeImage::CreateFromPath
Summary
Electron is an open source framework for writing cross-platform desktop applications using JavaScript, HTML and CSS. In versions prior to 28.3.2, 29.3.3, and 30.0.3, the nativeImage.createFromPath() and nativeImage.createFromBuffer() functions call a function downstream that is vulnerable to a heap buffer overflow. An Electron program that uses either of the affected functions is vulnerable to a buffer overflow if an attacker is in control of the image's height, width, and contents. This issue has been patched in versions 28.3.2, 29.3.3, and 30.0.3. There are no workarounds for this issue.

Title
heap-buffer-overflow in Vim
Summary
Vim is an open source, command line text editor. Patch v9.1.0038 optimized how the cursor position is calculated and removed a loop, that verified that the cursor position always points inside a line and does not become invalid by pointing beyond the end of
a line. Back then we assumed this loop is unnecessary. However, this change made it possible that the cursor position stays invalid and points beyond the end of a line, which would eventually cause a heap-buffer-overflow when trying to access the line pointer at
the specified cursor position. It's not quite clear yet, what can lead to this situation that the cursor points to an invalid position. That's why patch v9.1.0707 does not include a test case. The only observed impact has been a program crash. This issue has been addressed in with the patch v9.1.0707. All users are advised to upgrade.

Title
heap-buffer-overflow in ins_typebuf() in Vim < 9.1.0697
Summary
Vim is an improved version of the unix vi text editor. When flushing the typeahead buffer, Vim moves the current position in the typeahead buffer but does not check whether there is enough space left in the buffer to handle the next characters. So this may lead to the tb_off position within the typebuf variable to point outside of the valid buffer size, which can then later lead to a heap-buffer overflow in e.g. ins_typebuf(). Therefore, when flushing the typeahead buffer, check if there is enough space left before advancing the off position. If not, fall back to flush current typebuf contents. It's not quite clear yet, what can lead to this situation. It seems to happen when error messages occur (which will cause Vim to flush the typeahead buffer) in comnination with several long mappgins and so it may eventually move the off position out of a valid buffer size. Impact is low since it is not easily reproducible and requires to have several mappings active and run into some error condition. But when this happens, this will cause a crash. The issue has been fixed as of Vim patch v9.1.0697. Users are advised to upgrade. There are no known workarounds for this issue.

Title
heap-buffer-overflow in do_search() in Vim < 9.1.0689
Summary
Vim is an open source command line text editor. When performing a search and displaying the search-count message is disabled (:set shm+=S), the search pattern is displayed at the bottom of the screen in a buffer (msgbuf). When right-left mode (:set rl) is enabled, the search pattern is reversed. This happens by allocating a new buffer. If the search pattern contains some ASCII NUL characters, the buffer allocated will be smaller than the original allocated buffer (because for allocating the reversed buffer, the strlen() function is called, which only counts until it notices an ASCII NUL byte ) and thus the original length indicator is wrong. This causes an overflow when accessing characters inside the msgbuf by the previously (now wrong) length of the msgbuf. The issue has been fixed as of Vim patch v9.1.0689.

"value": "Vim is an open source command line text editor. When performing a search and displaying the search-count message is disabled (:set shm+=S), the search pattern is displayed at the bottom of the screen in a buffer (msgbuf). When right-left mode (:set rl) is enabled, the search pattern is reversed. This happens by allocating a new buffer. If the search pattern contains some ASCII NUL characters, the buffer allocated will be smaller than the original allocated buffer (because for allocating the reversed buffer, the strlen() function is called, which only counts until it notices an ASCII NUL byte ) and thus the original length indicator is wrong. This causes an overflow when accessing characters inside the msgbuf by the previously (now wrong) length of the msgbuf. The issue has been fixed as of Vim patch v9.1.0689."

Mitigation
Pre-design: Use a language or compiler that performs automatic bounds checking.
Mitigation
Architecture and Design
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation MIT-10
Operation
Build and Compilation
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
Operation
Build and Compilation
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
Implementation
Implement and perform bounds checking on input.
Mitigation
Implementation
Strategy: Libraries or Frameworks
Do not use dangerous functions such as gets. Look for their safe equivalent, which checks for the boundary.
Mitigation
Operation
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.
