CVE-2007-6438: Unspecified vulnerability in the SMB dissector in Wireshark (formerly Ethereal) 0.99.6 allows remote attack...

Security readout for executives and security teams

This is a denial-of-service flaw in Wireshark's SMB packet parser, reported for Wireshark 0.99.6. A malicious network packet or capture could crash the analysis tool. The sources do not indicate data theft, code execution, or active exploitation. Exposure is most likely where legacy Wireshark or tshark 0.99.6 remains installed, especially in monitoring, forensics, or automated packet-processing workflows that inspect untrusted SMB traffic or capture files. Prioritize remediation where Wireshark is used operationally for monitoring or incident response. For normal desktops, urgency is lower, but unsupported legacy packet-analysis tools should still be removed or updated. Mitigation focus: Identify Wireshark and tshark installations running version 0.99.6.; Apply relevant Wireshark or operating-system vendor security updates.; Retire unsupported legacy Wireshark packages from analyst and sensor systems..
