Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: A critical **Double Free** flaw in `libbiosig` v2.5.0. <br>π₯ **Consequences**: The BrainVision header parser mishandles memory, leading to crashes or arbitrary code execution. CVSS Score is **HIGH** (9.8).
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: **CWE-415** (Double Free). <br>π **Flaw**: The code frees a memory pointer twice during BrainVision header parsing. This corrupts the heap, destabilizing the application.
Q3Who is affected? (Versions/Components)
π’ **Vendor**: The Biosig Project. <br>π¦ **Product**: `libbiosig` (BioSignal Processing Library). <br>β οΈ **Affected**: Version **2.5.0** specifically. Open-source biomedical signal tools.
Q4What can hackers do? (Privileges/Data)
π **Privileges**: **Full Control**. <br>π **Data**: High Confidentiality, Integrity, and Availability impact.β¦
π **Threshold**: **LOW**. <br>π **Network**: Attack Vector is **Network** (AV:N). <br>π€ **Auth**: **None** required (PR:N, UI:N). Simple processing of a malicious file triggers it.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π **Public Exp?**: **Yes**. <br>π **Source**: Talos Intelligence report (TALOS-2024-1917) and Fedora package announcements confirm active tracking and potential exploitation awareness.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Scan for `libbiosig` version **2.5.0**. <br>π§ͺ **Test**: Process crafted BrainVision header files. If the application crashes or exhibits heap corruption, you are vulnerable.
