AI Analysis
Technical Summary
The FMP/NOTIFY protocol dissector in Wireshark versions 4.4.0 through 4.4.16 and 4.6.0 through 4.6.6 contains a flaw that leads to a crash of the application, enabling denial of service. The vulnerability is characterized by a crash triggered during protocol dissection, impacting availability. The CVSS 3.1 vector indicates the attack requires local access (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), scope unchanged (S:U), no confidentiality or integrity impact (C:N/I:N), and high impact on availability (A:H). Multiple Ubuntu package versions are affected, but no patch or remediation information is provided in the source data.
Potential Impact
Successful exploitation causes a denial of service by crashing Wireshark, impacting availability. There is no impact on confidentiality or integrity. The attack requires local access and user interaction, limiting remote exploitation potential.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, avoid opening untrusted capture files or disable the FMP/NOTIFY protocol dissector if possible to reduce exposure.
