Stack-based Buffer Overflow
A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than it was allocated to hold.
How It Works
A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than it was allocated to hold. The stack stores local variables, function parameters, and critical control information including the return address that tells the CPU where to resume execution after a function completes. When an attacker overflows a buffer, they can overwrite adjacent memory, including this return address.
The classic exploitation path involves carefully crafting input to overwrite the return address with a pointer to attacker-controlled code. Historically, attackers would inject shellcode directly into the overflowed buffer, then redirect execution to it. Modern defenses like Data Execution Prevention (DEP/NX) mark the stack as non-executable, forcing attackers to use Return-Oriented Programming (ROP) instead—chaining together existing code snippets ("gadgets") to perform malicious operations without injecting new code.
Address Space Layout Randomization (ASLR) randomizes memory addresses to make exploitation harder, but attackers can defeat it through information disclosure vulnerabilities that leak memory addresses. Stack canaries—random values placed between buffers and control data—can detect overwrites, but may be bypassed through brute-force attacks or by carefully avoiding them in partial overwrites.
Impact
- Arbitrary code execution at the privilege level of the vulnerable process
- Complete system compromise if the vulnerable process runs with elevated privileges (root/SYSTEM)
- Memory corruption leading to crashes and denial of service
- Bypass of authentication mechanisms by redirecting execution flow around security checks
- Data theft or modification through code injection that accesses sensitive memory regions
Real-World Examples
The Morris Worm (1988) exploited a stack overflow in the Unix fingerd daemon, becoming one of the first major internet worms. The Code Red worm (2001) leveraged a stack overflow in Microsoft IIS (CVE-2001-0500) to compromise hundreds of thousands of web servers, demonstrating the massive scale of automated exploitation.
More recently, EternalBlue exploited stack corruption in Windows SMB (CVE-2017-0144), enabling the WannaCry and NotPetya ransomware outbreaks that caused billions in damage. The Heartbleed bug (CVE-2014-0160), while technically a heap-based read overflow, demonstrated how buffer handling errors remain prevalent even in security-critical software like OpenSSL.
Mitigation
- Stack canaries (compile with
-fstack-protector-allor equivalent) to detect overwrites before return - Address Space Layout Randomization (ASLR) to randomize memory locations
- DEP/NX bit enforcement to prevent code execution from stack memory
- Memory-safe string functions (use
strncpy,snprintf,strlcpyinstead ofstrcpy,sprintf,gets) - Compiler hardening flags (
-D_FORTIFY_SOURCE=2, control-flow integrity) - Input validation with strict bounds checking on all externally-supplied data
- Memory-safe languages (Rust, Go) for new development to eliminate the vulnerability class entirely

Local privilege escalation in FreeBSD's libcasper(3) library affects FreeBSD 14.3, 14.4, and 15.0 releases prior to specified patch levels, where a missing FD_SETSIZE bounds check enables stack corruption when a low-privileged attacker forces a setuid-root application to allocate file descriptors above 1024. Successful exploitation yields root-equivalent privileges on the local host. No public exploit identified at time of analysis and EPSS scores exploitation probability at just 0.02%, but the issue is confirmed by a FreeBSD security advisory (SA-26:22.libcasper).
Local privilege escalation in the FreeBSD kernel's setcred(2) system call lets an unprivileged local user overflow a fixed-size kernel stack buffer and potentially execute arbitrary code with kernel privileges. The flaw affects the FreeBSD 14.3, 14.4 and 15.0 release lines and stems from the length of the caller-supplied supplementary groups list being validated only after it has already been copied into the buffer. There is no public exploit identified at time of analysis, the EPSS probability is very low (0.02%), and CISA SSVC records no known exploitation, but the technical impact is rated total.
Stack-based buffer overflow in Netatalk versions 2.0.4 through 4.4.2 allows authenticated remote attackers to corrupt memory via UCS-2 type confusion in the convert_charset() function, leading to high-impact compromise of confidentiality, integrity, and availability. The flaw affects Netatalk, the open-source AppleTalk/AFP file server commonly used to share files with macOS clients, and is fixed in version 4.4.3. No public exploit identified at time of analysis, though the high CVSS of 8.8 and low attack complexity warrant prompt patching.
Stack-based buffer overflow in the EPSON L14150 (firmware FL27PB) is reachable remotely and unauthenticated through the RAW/JetDirect print service on TCP port 9100, letting an attacker crash or potentially execute code on the device. The MITRE description claims arbitrary code execution, though the CVSS vector scores only availability impact (C:N/I:N/A:H) and CISA SSVC rates technical impact as 'partial', so the practical outcome is more consistent with a denial-of-service/device crash than confirmed RCE. Publicly available exploit code exists (POC on GitHub/gist), but it is not in CISA KEV and EPSS is low (0.19%).
Stack-based buffer overflow in lwIP's SNMPv3 USM handler exposes embedded and IoT devices running versions 2.1.0 through 2.2.1 to remote unauthenticated code execution. The flaw in snmp_parse_inbound_frame() allowed an attacker-controlled msgAuthenticationParameters TLV length to be used directly in a stack buffer copy without bounds validation - a protective assertion had been explicitly commented out in the codebase. With CVSS 4.0 scoring 8.9, SSVC classifying the attack as automatable with total technical impact, and proof-of-concept code in existence (E:P), this is a high-priority remediation target for any network-accessible lwIP deployment with SNMPv3 enabled; no CISA KEV listing has occurred at time of analysis.
Stack buffer overflow in PostgreSQL's refint module allows low-privileged database users to execute arbitrary code as the database operating system user across all supported versions before 14.23, 15.18, 16.14, 17.10, and 18.4. The vulnerability enables two distinct attack paths: direct stack overflow leading to OS-level code execution, and SQL injection when applications expose user-controlled columns configured as refint cascade primary keys. With CVSS 8.8 (AV:N/AC:L/PR:L) and network-based exploitation requiring only low-privilege database credentials, this represents a critical privilege escalation risk for PostgreSQL deployments. No active exploitation (CISA KEV) or public POC identified at time of analysis.

SSVC assessment marks this as automatable with total technical impact but no confirmed exploitation.
Stack-based buffer overflow in the arduino-esp32 WebServer multipart form parser (all releases prior to 3.3.8) lets a remote attacker crash the device and potentially achieve code execution by sending an oversized multipart/form-data boundary value. The parser sizes a stack Variable Length Array from the attacker-controlled Content-Type boundary field with no length cap, so a boundary longer than ~8000 characters overruns the 8192-byte loopTask stack. Publicly available proof-of-concept exploit code exists (SSVC: poc); it is not listed in CISA KEV and EPSS remains low at 0.20%.
Arbitrary code execution in Adobe After Effects 26.0, 25.6.4 and all earlier versions arises from a stack-based buffer overflow (CWE-121) triggered when a victim opens a maliciously crafted project or media file, running code in the context of the current user. Reported by Adobe and tracked in APSB26-48, it carries a CVSS 7.8 (High) with a local attack vector and required user interaction; there is no public exploit identified at time of analysis, and the EPSS score is 0.01% (1st percentile). SSVC indicates no observed exploitation but total technical impact, making this a patch-on-schedule priority rather than an emergency.

A publicly available proof-of-concept exists (GitHub Gist reference), but CISA KEV status is not confirmed, and EPSS data is unavailable. The low attack complexity (AC:L) and network attack vector (AV:N) make this readily exploitable against exposed instances, though the impact is currently limited to availability (A:H) with no confirmed confidentiality or integrity impacts.
Remote code execution in cannelloni v2.0.0 allows unauthenticated network attackers to crash the service or execute arbitrary code by sending malformed CAN FD frames that trigger buffer overflows in two separate parsing functions (parseCANFrame in parser.cpp and decodeFrame in decoder.cpp). The CVSS score of 9.8 reflects network-accessible exploitation requiring no authentication or user interaction, with complete system compromise possible. Public proof-of-concept code exists (GitHub Gist reference), elevating immediate exploitation risk despite no CISA KEV listing, suggesting targeted rather than mass exploitation scenarios.
Stack buffer overflow in AGL agl-service-can-low-level's uds-c library enables remote code execution on vulnerable automotive ECUs. The send_diagnostic_request function copies up to 7 bytes into a 6-byte stack buffer without bounds checking, allowing 1-4 bytes of controlled stack corruption. On 32-bit ARM ECUs without stack canaries (common in automotive deployments), attackers can overwrite return addresses to achieve arbitrary code execution. CVSS 7.5 with network attack vector and no authentication required indicates critical exposure, though CVSS impact vector (C:N/I:N/A:H) appears inconsistent with RCE capability described - vendor assessment may undervalue confidentiality/integrity impact of code execution.
Stack buffer overflow in miaofng/uds-c library allows adjacent network attackers to execute arbitrary code via crafted diagnostic payload. The send_diagnostic_request function allocates only 6 bytes for MAX_DIAGNOSTIC_PAYLOAD_SIZE but accepts up to 7 bytes of payload (MAX_UDS_REQUEST_PAYLOAD_LENGTH), enabling 4-byte overflow when combined with pid_length=2. Affects commit e506334e270d77b20c0bc259ac6c7d8c9b702b7a from October 2016 and likely later versions unless patched. No CISA KEV listing or EPSS data indicates exploitation remains theoretical; vulnerability appears in automotive diagnostic library with limited deployment exposure.
