Buffer overflow vulnerabilities occur when software unexpectedly writes more data too memory storage than has been allocated for that data. The extra information spills into other memory, altering it. Smart attackers can feed carefully crafted data into software with these bugs to hijack the flow of the program so that it can be made to do things it was not intended to do.These vulnerabilities can lead to data corruption, sensitive data exposure, program crashes, and unauthorized code execution. Threat actors frequently exploit these vulnerabilities to gain initial access to an organization’s systems.
Most software developers know what a buffer overflow vulnerability is, but buffer overflow attacks against both legacy and newly-developed applications are still quite common. The list includes two vulnerabilities of Microsoft CVE-2025-21333 (a vulnerability for local attackers to acquire system rights in a container-based environment) and CVE-20124-49138 (Windows Common Log File System Driver included a vulnerability that causes the entire system to increase the authority).
The most serious vulnerability in the list is the defect of the VMware V Center (CVE-2024-38812). This is a vulnerability that the second patch was distributed a few months after the Broadcom admitted that the first patch did not completely solve the problem. The vulnerability was a problem of heap overflow that occurred in the DCERPC protocol implementation of the DCERPC protocol.
Another major vulnerability is the Stack Overflow Bug (CVE-2025-0282) found in ivanti’s Connect secure. It scored 9 points in the CVSS severity evaluation, and in January of this year, Ivanti distributed the patch after being exploited by the zero-day attack. In the past, companies that have relied on vulnerable programming languages such as C and C++ are gradually switching to languages that guarantee memory safety such as Rust, Swift, and Python.

The Shift Towards Memory Safe Languages

Interview with Memory Safety Expert, Dr. Emma Thompson
We sat down with Dr. Emma Thompson, a renowned expert on memory safety, to discuss the nuances of buffer overflow vulnerabilities and the shift towards safer programming languages.
Q: Can you explain in simple terms what a buffer overflow vulnerability is and how it occurs?
Dr. Thompson: A buffer overflow vulnerability occurs when a program writes more data into a buffer, or memory space, than it is allocated to hold. This overflow can corrupt adjacent memory, leading to unpredictable behavior. Attackers exploit this by carefully crafting input data that causes the buffer to overflow, allowing them to inject malicious code or alter program flow.
Q: How do these vulnerabilities impact modern software systems?
Dr. Thompson: Buffer overflows can lead to severe consequences, including data corruption, exposure of sensitive information, system crashes, and unauthorized code execution. These vulnerabilities can be used as entry points for attackers to gain control over systems, leading to potential data breaches and system compromises.
Q: Can you discuss the recent vulnerability found in Ivanti’s Connect Secure?
Dr.Thompson: The Stack Overflow Bug (CVE-2025-0282) in Ivanti’s Connect Secure is a notable example.This vulnerability scored high on the CVSS severity scale, indicating its critical nature. It allowed attackers to execute arbitrary code, posing a significant risk to organizations using the software. Ivanti’s quick response with a patch is commendable, but it underscores the importance of proactive security measures.
Q: What are the benefits of shifting to memory-safe languages like Rust, Swift, and Python?
Dr. Thompson: Languages like Rust, Swift, and Python offer built-in mechanisms to prevent buffer overflows and other memory-related issues. Rust, as a notable example, uses ownership and borrowing rules to ensure memory safety without a garbage collector. Swift has strong type safety and automatic memory management, while Python’s dynamic typing and garbage collection help mitigate many memory errors. Switching to these languages can significantly reduce the risk of buffer overflows and improve overall software security.
Q: What advice would you give to developers and organizations looking to enhance their security posture?
Dr. Thompson: I would advise developers to adopt secure coding practices and use static analysis tools to identify potential vulnerabilities. Organizations should invest in regular security audits and training for their progress teams. Additionally, keeping software up-to-date with the latest patches is crucial to addressing known vulnerabilities.
Conclusion
buffer overflow vulnerabilities remain a significant threat in the world of cybersecurity. As we’ve discussed, these vulnerabilities can lead to severe consequences, including data corruption, unauthorized code execution, and system compromises. the shift towards memory-safe programming languages like Rust, Swift, and Python offers a promising solution to mitigate these risks. By adopting proactive security measures and investing in secure coding practices, developers and organizations can enhance their security posture and protect against these possibly devastating attacks.
