CWE-121
Stack-based Buffer Overflow
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).

Title
iccDEV is vulnerable to stack-buffer-overflow in icFixXml()
Summary
iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. Prior to version 2.3.1.2, stack-based buffer overflow in icFixXml() function when processing malformed ICC profiles, allows potential arbitrary code execution through crafted NamedColor2 tags. This issue has been patched in version 2.3.1.2.

Title
iccDEV vulnerable to Stack-based Buffer Overflow in CIccTagFloatNum::GetValues()
Summary
iccDEV provides a set of libraries and tools that allow for the interaction, manipulation, and application of ICC color management profiles. Prior to version 2.3.1.3, there is a stack-buffer-overflow vulnerability in CIccTagFloatNum<>::GetValues(). This is triggered when processing a malformed ICC profile. The vulnerability allows an out-of-bounds write on the stack, potentially leading to memory corruption, information disclosure, or code execution when processing specially crafted ICC files. This issue has been patched in version 2.3.1.3.

Title
Wavlink WL-NU516U1 adm.cgi sub_40785C stack-based overflow
Summary
A weakness has been identified in Wavlink WL-NU516U1 20251208. Affected by this issue is the function sub_40785C of the file /cgi-bin/adm.cgi. This manipulation of the argument time_zone causes stack-based buffer overflow. The attack can be initiated remotely. The attack is considered to have high complexity. The exploitation is known to be difficult. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Title
Wavlink WL-NU516U1 adm.cgi sub_406194 stack-based overflow
Summary
A security vulnerability has been detected in Wavlink WL-NU516U1 up to 130/260. This affects the function sub_406194 of the file /cgi-bin/adm.cgi. Such manipulation of the argument firmware_url leads to stack-based buffer overflow. The attack can be launched remotely. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

Title
time affected by a stack exhaustion denial of service attack
Summary
time provides date and time handling in Rust. From 0.3.6 to before 0.3.47, when user-provided input is provided to any type that parses with the RFC 2822 format, a denial of service attack via stack exhaustion is possible. The attack relies on formally deprecated and rarely-used features that are part of the RFC 2822 format used in a malicious manner. Ordinary, non-malicious input will never encounter this scenario. A limit to the depth of recursion was added in v0.3.47. From this version, an error will be returned rather than exhausting the stack.

Title
Wazuh Database Synchronization Vulnerable to Stack-based Buffer Overflow via snprintf Integer Underflow
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. Starting in version 4.4.0 and prior to version 4.14.3, a stack-based buffer overflow vulnerability exists in the Wazuh Database synchronization module (`wdb_delta_event.c`). The SQL query construction logic allows for an integer underflow when calculating the remaining buffer size. This occurs because the code incorrectly aggregates the return value of `snprintf`. If a specific database synchronization payload exceeds the size of the query buffer (2048 bytes), the size calculation wraps around to a massive integer, effectively removing bounds checking for subsequent writes. This allows an attacker to corrupt the stack, leading to a Denial of Service (DoS) or potentially RCE. Version 4.14.3 fixes the issue.

Starting in version 4.4.0 and prior to version 4.14.3, a stack-based buffer overflow vulnerability exists in the Wazuh Database synchronization module (`wdb_delta_event.c`). The SQL query construction logic allows for an integer underflow when calculating the remaining buffer size. This occurs because the code incorrectly aggregates the return value of `snprintf`. If a specific database synchronization payload exceeds the size of the query buffer (2048 bytes), the size calculation wraps around to a massive integer, effectively removing bounds checking for subsequent writes. This allows an attacker to corrupt the stack, leading to a Denial of Service (DoS) or potentially RCE. Version 4.14.3 fixes the issue."

Title
Wazuh has Stack-Based Buffer Overflow in Security Configuration Assessment JSON Parser
Summary
Wazuh is a free and open source platform used for threat prevention, detection, and response. Starting in version 3.9.0 and prior to version 4.14.3, multiple stack-based buffer overflows exist in the Security Configuration Assessment (SCA) decoder (`wazuh-analysisd`). The use of `sprintf` with a floating-point (`%lf`) format specifier on a fixed-size 128-byte buffer allows a remote attacker to overflow the stack. A specially crafted JSON event can trigger this overflow, leading to a denial of service (crash) or potential RCE on the Wazuh manager. The vulnerability is located in `/src/analysisd/decoders/security_configuration_assessment.c`, within the `FillScanInfo` and `FillCheckEventInfo` functions. In multiple locations, a 128-byte buffer (`char value[OS_SIZE_128];`) is allocated on the stack to hold the string representation of a number from a JSON event. The code checks if the number is an integer or a double. If it's a double, it uses `sprintf(value, "%lf", ...)` to perform the conversion. This `sprintf` call is unbounded. If a floating-point number with a large exponent (e.g., `1.0e150`) is provided, `sprintf` will attempt to write its full string representation (a "1" followed by 150 zeros), which is larger than the 128-byte buffer, corrupting the stack. Version 4.14.3 patches the issue.

Title
ImageMagick has stack buffer overflow in FTXT reader via oversized integer field
Summary
ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to version 7.1.2-15, a stack-based buffer overflow exists in the ImageMagick FTXT image reader. A crafted FTXT file can cause out-of-bounds writes on the stack, leading to a crash. Version 7.1.2-15 contains a patch.

Mitigation ID: MIT-10
Phases: Operation, Build and Compilation
Strategy: Environment Hardening
Description:
- 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
Phase: Architecture and Design
Description:
- Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation
Phase: Implementation
Description:
- Implement and perform bounds checking on input.
Mitigation
Phase: Implementation
Description:
- Do not use dangerous functions such as gets. Use safer, equivalent functions which check for boundary errors.
Mitigation ID: MIT-11
Phases: Operation, Build and Compilation
Strategy: Environment Hardening
Description:
- 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].
