CVE-2022-0392 Heap-based Buffer Overflow in GitHub repository vim prior to 8.2.

CVE-2022-0392 Heap-based Buffer Overflow in GitHub repository vim prior to 8.2.

This is a common, yet critical mistake. In this example, the buffer overflow was intentionally introduced through a buffer. An attacker can exploit a buffer overflow by crafting a malicious script that can be executed by the server. When a user accesses the vulnerable script, the server will parse and execute the malicious code. As a result, the server can be taken over and used to deliver malicious code to other users. This is an example of a buffer overflow in a git repository. Due to its critical nature, the vulnerability was announced to the public on October 2, 2017. On GitHub, there are two methods for announcing a vulnerability. The first is the vendor- MIT or “mossie” approach. This is the method that was used for the GitHub buffer overflow.

Vendor- MIT:

How it works
The vendor- MIT approach is when a vendor, such as a bug bounty program, announces a vulnerability to the public. The vendor will then provide the exploit code and details of how to use it. This approach allows the vendor to get credit for discovering and disclosing the vulnerability while also protecting their customers from the exploit code.

Vendor MIT Approach

This method is followed when the vendor already knows about the vulnerability and has made a patch. In this scenario, the vendor will generally disclose the vulnerability in a blog post, tweet, or email to their customers. This approach is helpful because it provides a means for users to find and install the patch quickly.
The second method is through GitHub’s public disclosure process. This process requires that the vendor send an email to security@github.com with details of the vulnerability (CVE-2022-0392) and an attached patch (GitHub-18c5029). If you are curious about whether your specific product or service was involved in this vulnerability, you can search on GitHub's CVE database or contact GitHub Support at security@github.com.

Vendor- MIT announcement

The second is the public- CVE or “cve” approach. This is the method that was used for a vulnerability that was publicly announced on October 2, 2017.

Vendor- MIT Approach

This approach works for a vulnerability that was introduced by an external source such as a company or researcher. It is also utilized when the vulnerability is known to exist inside of a product but is not known to be exploited in production. The vendor- MIT approach requires the vendor to first contact the original reporter and obtain their permission to announce the vulnerability publicly. This makes it harder for hackers to weaponize the vulnerability.
