Common Weakness Enumeration

CWE-416

Allowed

Use After Free

Abstraction: Variant · Status: Stable

API response cwe.mitre.org

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

9821 vulnerabilities reference this CWE, most recent first.

CVE-2022-37387 (GCVE-0-2022-37387)

Vulnerability from cvelistv5 – Published: 2023-03-29 00:00 – Updated: 2025-02-14 20:32
VLAI
Summary
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Foxit PDF Reader 11.2.2.53575. 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 handling of AcroForms. 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-17552.

CVE-2022-37382 (GCVE-0-2022-37382)

Vulnerability from cvelistv5 – Published: 2023-03-29 00:00 – Updated: 2025-02-14 20:31
VLAI
Summary
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Foxit PDF Reader 11.2.1.53537. 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 removeIcon method. 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 in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-17383.

CVE-2022-37332 (GCVE-0-2022-37332)

Vulnerability from cvelistv5 – Published: 2022-11-21 16:05 – Updated: 2025-04-15 18:40
VLAI
Summary
A use-after-free vulnerability exists in the JavaScript engine of Foxit Software's PDF Reader, version 12.0.1.12430. A specially-crafted PDF document can trigger the reuse of previously freed memory via misusing media player API, 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.
Severity

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.
