CVE-2012-3826: Multiple integer underflows in Wireshark 1.4.x before 1.4.13 and 1.6.x before 1.6.8 allow remote attackers...

Multiple integer underflows in Wireshark 1.4.x before 1.4.13 and 1.6.x before 1.6.8 allow remote attackers to cause a denial of service (loop) via vectors related to the R3 dissector, a different vulnerability than CVE-2012-2392.

Security readout for executives and security teams

This flaw can make affected Wireshark versions hang when they process certain R3-related network data. The business impact is disruption to packet analysis, monitoring, or forensic workflows rather than data theft or system takeover, based on the supplied sources. Exposure is most likely where old Wireshark 1.4.x or 1.6.x installations process untrusted captures or live network traffic. Current environments are less likely exposed unless legacy analyst workstations or appliances remain unmanaged. Treat as a legacy hygiene issue with moderate urgency. Prioritize remediation where Wireshark supports monitoring, incident response, or forensic operations, because availability loss during investigations can materially slow response. Mitigation focus: Upgrade Wireshark 1.4.x to 1.4.13 or later.; Upgrade Wireshark 1.6.x to 1.6.8 or later.; Follow Wireshark advisory WNPA-SEC-2012-08 for vendor-specific guidance..
