Description
A stack-based buffer overflow vulnerability exists in the MFER parsing functionality of The Biosig Project libbiosig 3.9.0 and Master Branch (35a819fa). A specially crafted MFER file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.
A stack-based buffer overflow vulnerability has been identified in The Biosig Project's libbiosig version 3.9.0 and the Master Branch (35a819fa). This vulnerability arises in the MFER parsing functionality, where a specially crafted MFER file can be used to execute arbitrary code. The issue is triggered by the `sopen_extended` function, which processes MFER files by reading tags, data lengths, and values. The vulnerability occurs when the length of the data exceeds the expected size, allowing for a buffer overflow when the data is processed.
Users are advised to update to the patched version of libbiosig, which is available on the project's official website.
