Name of the Vulnerable Software and Affected Versions Wireshark versions 2.4.0 through 2.4.15 Wireshark versions 2.6.0 through 2.6.9 Wireshark versions 3.0.0 through 3.0.2

Description The issue is related to the ASN.1 BER dissector and related dissectors in Wireshark, which could crash due to a buffer overflow. This could allow a remote attacker to cause a denial of service. The problem was addressed by properly restricting buffer increments in the epan/asn1.c file.
