MetricsAV:N/AC:M/Au:N/C:N/I:N/A:C
Name of the Vulnerable Software and Affected Versions Wireshark versions 3.2.0 through 3.2.5
Description The issue is related to the Kafka protocol dissector component in Wireshark, which could crash due to a double free error during LZ4 decompression. This could potentially allow a remote attacker to cause a denial of service. The problem was addressed by modifying the epan/dissectors/packet-kafka.c file to avoid the double free error.
Recommendations For Wireshark versions 3.2.0 through 3.2.5, update the software to a version where the issue has been fixed, specifically by applying the changes made to the epan/dissectors/packet-kafka.c file to avoid the double free error during LZ4 decompression. As a temporary workaround, consider disabling the Kafka protocol dissector until a patch is available.
