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().
6345 vulnerabilities reference this CWE, most recent first.
GHSA-44QM-928X-6P3G
Vulnerability from github – Published: 2024-01-02 06:30 – Updated: 2024-03-28 15:30A vulnerability was found in Perl. This security issue occurs while Perl for Windows relies on the system path environment variable to find the shell (cmd.exe). When running an executable that uses the Windows Perl interpreter, Perl attempts to find and execute cmd.exe within the operating system. However, due to path search order issues, Perl initially looks for cmd.exe in the current working directory. This flaw allows an attacker with limited privileges to placecmd.exe in locations with weak permissions, such as C:\ProgramData. By doing so, arbitrary code can be executed when an administrator attempts to use this executable from these compromised locations.

Vulnerability from github – Published: 2022-02-19 00:01 – Updated: 2022-03-01 00:00This vulnerability allows remote attackers to execute arbitrary code on affected installations of Bentley MicroStation CONNECT 10.16.0.80. 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 DGN files. 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-15534.

GHSA-45Q4-4828-537R
Vulnerability from github – Published: 2026-05-08 15:31 – Updated: 2026-08-31 15:34In the Linux kernel, the following vulnerability has been resolved:
netfilter: flowtable: strictly check for maximum number of actions
The maximum number of flowtable hardware offload actions in IPv6 is:
- ethernet mangling (4 payload actions, 2 for each ethernet address)
- SNAT (4 payload actions)
- DNAT (4 payload actions)
- Double VLAN (4 vlan actions, 2 for popping vlan, and 2 for pushing) for QinQ.
- Redirect (1 action)
Which makes 17, while the maximum is 16. But act_ct supports for tunnels actions too. Note that payload action operates at 32-bit word level, so mangling an IPv6 address takes 4 payload actions.
Update flow_action_entry_next() calls to check for the maximum number of supported actions.
While at it, rise the maximum number of actions per flow from 16 to 24 so this works fine with IPv6 setups.

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.
