Common Weakness Enumeration
CWE-416
AllowedUse After Free
Abstraction: Variant · Status: Stable
The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9851 vulnerabilities reference this CWE, most recent first.

Trimble SketchUp Viewer SKP File Parsing Use-After-Free Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Trimble SketchUp Viewer. 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 SKP files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-24103.

GHSA-RV75-9926-88QP
Vulnerability from github – Published: 2022-05-24 19:07 – Updated: 2022-05-24 19:07
VLAI
Details
A vulnerability has been identified in JT2Go (All versions < V13.2), Teamcenter Visualization (All versions < V13.2). The Jt981.dll library in affected applications lacks proper validation of user-supplied data prior to performing further free operations on an object when parsing JT files. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-13430)

Mitigation
Architecture and Design
Strategy: Language Selection
Choose a language that provides automatic memory management.
Mitigation
Implementation
Strategy: Attack Surface Reduction
When freeing pointers, be sure to set them to NULL once they are freed. However, the utilization of multiple or complex data structures may lower the usefulness of this strategy.
