CVE-2020-17498
In Wireshark 3.2.0 to 3.2.5, the Kafka protocol dissector could crash.
MEDIUM 6.5EPSS 2.58%
Does this matter?
Lower severity and a low EPSS score (2.58%). Track it; it rarely justifies an emergency change on its own.
Description
In Wireshark 3.2.0 to 3.2.5, the Kafka protocol dissector could crash. This was addressed in epan/dissectors/packet-kafka.c by avoiding a double free during LZ4 decompression.
