What is CVE-2021-39293?

In versions of Go prior to 1.16.8 and 1.17.x before 1.17.1, a vulnerability in the archive/zip package can be exploited by providing a specially crafted archive header. This misleading header can falsely indicate the presence of numerous files, leading to a panic in NewReader or OpenReader functions. The issue arises from an incomplete fix related to a previous vulnerability, showcasing the need for comprehensive security measures. Developers and organizations relying on affected versions should prioritize upgrading to mitigate potential Denial of Service risks.
