Q1What is this vulnerability? (Essence + Consequences)
π¨ **Essence**: Stack Buffer Overflow in Wireshark's DECT parser. π₯ **Consequences**: Remote attackers can execute arbitrary code via crafted .pcap files. Critical risk to system integrity!
Q2Root Cause? (CWE/Flaw)
π‘οΈ **Root Cause**: Flaw in `epan/dissectors/packet-dect.c`. The DECT parser fails to handle input bounds correctly, leading to a stack overflow. π CWE not specified in data.
Q3Who is affected? (Versions/Components)
π₯ **Affected**: Wireshark versions **1.4.x prior to 1.4.5**. Specifically the DECT dissector component. π¦ Product: Wireshark (formerly Ethereal).
Q4What can hackers do? (Privileges/Data)
π **Attacker Action**: Execute **arbitrary code** on the victim's machine. π Access to system privileges depends on the user running Wireshark. No specific data theft mentioned, but code execution is key.
Q5Is exploitation threshold high? (Auth/Config)
β οΈ **Threshold**: **Low**. Requires opening a **crafted .pcap file**. No authentication needed. Just viewing the file triggers the vulnerability. π― Easy target.
Q6Is there a public Exp? (PoC/Wild Exploitation)
π’ **Exploit Status**: Public advisories exist (OSS-Security, CERT). π No specific PoC code provided in the data, but the vulnerability is well-documented and confirmed. Wild exploitation likely possible.
Q7How to self-check? (Features/Scanning)
π **Self-Check**: Check your Wireshark version. If it is **< 1.4.5**, you are vulnerable. π Look for DECT packet analysis features. Scan for .pcap files in untrusted directories.
Q8Is it fixed officially? (Patch/Mitigation)
β **Fix**: Yes! Update to **Wireshark 1.4.5** or later. π οΈ Vendor advisory confirms the fix. Fedora also released an update (FEDORA-2011-5621).
Q9What if no patch? (Workaround)
π§ **No Patch?**: **Disable DECT parsing** if possible. π« Do not open .pcap files from untrusted sources. Use a sandboxed environment if you must analyze suspicious traffic.
Q10Is it urgent? (Priority Suggestion)
π₯ **Urgency**: **HIGH**. Remote Code Execution (RCE) via simple file opening. π Patch immediately. This is a critical security flaw affecting a widely used tool.
