1) Buffer overflow (CVE-ID: CVE-2019-9209)
The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.
In Wireshark 2.4.0 to 2.4.12 and 2.6.0 to 2.6.6, the ASN.1 BER and related dissectors could crash. This was addressed in epan/dissectors/packet-ber.c by preventing a buffer overflow associated with excessive digits in time values.
