Technical Analysis

This vulnerability involves a crash in the ciscodump dissector component of Wireshark versions 4.6.0 through 4.6.6 and 4.4.0 through 4.4.16, leading to a denial of service condition. The issue is exploitable locally with low attack complexity and no privileges required, but user interaction is necessary. The vulnerability does not impact confidentiality or integrity but results in an availability impact due to application crash. Multiple specific Ubuntu package versions of Wireshark are affected.

Potential Impact

Successful exploitation causes denial of service by crashing the Wireshark application when processing certain ciscodump data. 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. No official fix or patch links are provided in the available data. Users should monitor Ubuntu security advisories for updates addressing this vulnerability.
