CWE-416

Use After Free

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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.

CVE-2019-5096 (GCVE-0-2019-5096)

Vulnerability from cvelistv5 – Published: 2019-12-03 21:52 – Updated: 2024-08-04 19:47
VLAI
Summary
An exploitable code execution vulnerability exists in the processing of multi-part/form-data requests within the base GoAhead web server application in versions v5.0.1, v.4.1.1 and v3.6.5. A specially crafted HTTP request can lead to a use-after-free condition during the processing of this request that can be used to corrupt heap structures that could lead to full code execution. The request can be unauthenticated in the form of GET or POST requests, and does not require the requested resource to exist on the server.

CVE-2019-5126 (GCVE-0-2019-5126)

Vulnerability from cvelistv5 – Published: 2020-01-16 21:59 – Updated: 2024-08-04 19:47

Summary
An exploitable use-after-free vulnerability exists in the JavaScript engine of Foxit PDF Reader, version 9.7.0.29435. A specially crafted PDF document can trigger a previously freed object in memory to be reused, resulting in arbitrary code execution. An attacker needs to trick the user to open the malicious file to trigger this vulnerability. If the browser plugin extension is enabled, visiting a malicious site can also trigger the vulnerability.

Mitigation

Phase: Architecture and Design

Strategy: Language Selection

Description:

  • Choose a language that provides automatic memory management.
Mitigation

Phase: Implementation

Strategy: Attack Surface Reduction

Description:

  • 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.
