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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
9983 vulnerabilities reference this CWE, most recent first.

Vulnerability from github – Published: 2023-07-19 15:30 – Updated: 2024-04-04 06:17
VLAI
Details
A use-after-free vulnerability exists in the JavaScript engine of Foxit Software’s PDF Reader, version 12.1.2.15332. By prematurely deleting objects associated with pages, a specially crafted PDF document can trigger the reuse of previously freed memory, which can lead to arbitrary code execution. An attacker needs to trick the user into opening the malicious file to trigger this vulnerability. Exploitation is also possible if a user visits a specially crafted, malicious site if the browser plugin extension is enabled.

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.
No CAPEC attack patterns related to this CWE.
