Off-by-one error in the dissect_6lowpan_iphc function in packet-6lowpan.c in Wireshark 1.4.0 through 1.4.3 on 32-bit platforms allows remote attackers to cause a denial of service (application crash) via a malformed 6LoWPAN IPv6 packet.

Security readout for executives and security teams

CVE-2011-1138 is a denial-of-service flaw in older Wireshark releases. A malformed 6LoWPAN IPv6 packet can crash Wireshark on 32-bit systems running versions 1.4.0 through 1.4.3. The business impact is analyst disruption, not confirmed data theft or system takeover. Exposure is likely limited to legacy 32-bit systems still running Wireshark 1.4.0 through 1.4.3 and processing 6LoWPAN IPv6 traffic or related packet captures. Modern supported Wireshark deployments are unlikely to be affected, but old distro packages should be verified. Treat this as a targeted legacy-tool availability issue. It should be remediated during normal vulnerability hygiene unless the organization relies on old 32-bit Wireshark systems for operational packet analysis. Mitigation focus: Upgrade Wireshark beyond versions 1.4.0 through 1.4.3.; Use vendor security updates from Wireshark or affected Linux distributions.; Retire unsupported 32-bit Wireshark analysis hosts where possible..
