epan/dissectors/packet-ppp.c in the PPP dissector in Wireshark 1.8.x before 1.8.3 uses incorrect OUI data structures during the decoding of (1) PPP and (2) LCP data, which allows remote attackers to cause a denial of service (assertion failure and application exit) via a malformed packet.

Security readout for executives and security teams

CVE-2012-5238 is a Wireshark crash issue. A malformed PPP or LCP packet can make affected Wireshark 1.8.x versions before 1.8.3 exit. The business impact is disruption to packet analysis workflows, not evidence of system takeover. Exposure is most likely on analyst workstations, monitoring systems, or automated tooling running Wireshark 1.8.x before 1.8.3 and processing untrusted PPP/LCP packets or capture files. Treat as a targeted operational stability issue. Remediate during normal vulnerability maintenance unless vulnerable Wireshark systems process untrusted captures in critical workflows. Mitigation focus: Upgrade Wireshark 1.8.x installations to 1.8.3 or later.; Check vendor advisory WNPA-SEC-2012-27 for official remediation details.; Limit processing of untrusted packet captures on vulnerable analyst systems..
