Common Weakness Enumeration

CWE-122

Heap-based Buffer Overflow

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
ext/openssl: Memory corruption in openssl_encrypt with AES-WRAP-PAD
Summary
In PHP versions 8.2.* before 8.2.32, 8.3.* before 8.3.32, 8.4.* before 8.4.23, 8.5.* before 8.5.8, the AES-WRAP-PAD algorithm implementation in OpenSSL extension contains a buffer allocation flaw. The output buffer for the AES key-wrap-with-padding operation is sized from the plaintext length without accounting for RFC 5649 expansion. This may cause OpenSSL to write beyond allocated memory, corrupting heap metadata and triggering application abort.

CVE-2026-14940 (GCVE-0-2026-14940)

Vulnerability from cvelistv5 – Published: 2026-07-07 13:54 – Updated: 2026-07-07 15:35

Title
389-ds-base: 389-ds-base: heap-buffer-overflow in dn normalization via quoted multivalued rdn
Summary
A heap-buffer-overflow flaw was found in 389 Directory Server (389-ds-base). When normalizing a Distinguished Name (DN) that contains a legacy-quoted value encoding a multivalued nested Relative Distinguished Name (RDN), the server can write past the end of a heap allocation while sorting RDN attribute-value pairs. An unauthenticated remote attacker can trigger this condition by sending an LDAP operation whose DN reaches the DN normalization routine, such as a search with a crafted base DN. This can corrupt heap memory and may cause denial of service.

Mitigation

Phases:

Description:

  • Pre-design: Use a language or compiler that performs automatic bounds checking.
Mitigation

Phase: Architecture and Design

Description:

  • Use an abstraction library to abstract away risky APIs. Not a complete solution.
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 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].
Mitigation

Phase: Implementation

Description:

  • Implement and perform bounds checking on input.
Mitigation

Phase: Implementation

Strategy: Libraries or Frameworks

Description:

  • Do not use dangerous functions such as gets. Look for their safe equivalent, which checks for the boundary.
Mitigation

Phase: Operation

Description:

  • 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.
