Security readout for executives and security teams
This flaw can make Wireshark stop working while analyzing specially crafted network data. It affects the BER dissector used for ASN.1 parsing and is an availability issue, not a data theft issue. Systems running affected Wireshark versions should be updated according to Wireshark or distribution guidance. Exposure is mainly on analyst workstations, packet-capture systems, and monitoring appliances that open untrusted traffic captures or decode live traffic with affected Wireshark versions. Prioritize remediation where Wireshark is used operationally on security monitoring or incident response systems. Business risk is service disruption and analyst tooling instability, not confirmed compromise. Mitigation focus: Identify Wireshark installations in the affected 1.2.x and 1.4.x ranges.; Apply Wireshark or operating-system vendor updates for CVE-2011-1142.; Restrict analysis of untrusted captures on unsupported legacy Wireshark builds..

Loop with Unreachable Exit Condition ('Infinite Loop')
Loop with Unreachable Exit Condition ('Infinite Loop') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
