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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.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-2021-31516 (GCVE-0-2021-31516)
Vulnerability from cvelistv5 – Published: 2021-06-29 14:33 – Updated: 2024-08-03 23:03

Summary
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Vector 35 Binary Ninja 2.3.2660 (Build ID 88f343c3). 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 BNDB 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-13670.

CVE-2021-32781 (GCVE-0-2021-32781)
Vulnerability from cvelistv5 – Published: 2021-08-24 20:50 – Updated: 2024-08-03 23:33
VLAI
Title
Continued processing of requests after locally generated response
Summary
Envoy is an open source L7 proxy and communication bus designed for large modern service oriented architectures. In affected versions after Envoy sends a locally generated response it must stop further processing of request or response data. However when local response is generated due the internal buffer overflow while request or response is processed by the filter chain the operation may not be stopped completely and result in accessing a freed memory block. A specifically constructed request delivered by an untrusted downstream or upstream peer in the presence of extensions that modify and increase the size of request or response bodies resulting in a Denial of Service when using extensions that modify and increase the size of request or response bodies, such as decompressor filter. Envoy versions 1.19.1, 1.18.4, 1.17.4, 1.16.5 contain fixes to address incomplete termination of request processing after locally generated response. As a workaround disable Envoy's decompressor, json-transcoder or grpc-web extensions or proprietary extensions that modify and increase the size of request or response bodies, if feasible.

CVE-2021-32944 (GCVE-0-2021-32944)
Vulnerability from cvelistv5 – Published: 2021-06-17 12:50 – Updated: 2024-08-03 23:33
VLAI
Summary
A use-after-free issue exists in the DGN file-reading procedure in the Drawings SDK (All versions prior to 2022.4) resulting from the lack of proper validation of user-supplied data. This can result in a memory corruption or arbitrary code execution, allowing attackers to cause a denial-of-service condition or execute code in the context of the current process.
Severity
No CVSS data available.

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.
No CAPEC attack patterns related to this CWE.
