Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2019-9208)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in Wireshark 2.4.0 to 2.4.12 and 2.6.0 to 2.6.6, the TCAP dissector could crash. This was addressed in epan/dissectors/asn1/tcap/tcap.cnf by avoiding NULL pointer dereferences. A remote attacker can perform a denial of service (DoS) attack.


2) 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.


3) NULL pointer dereference (CVE-ID: CVE-2019-9214)

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 RPCAP dissector could crash. This was addressed in epan/dissectors/packet-rpcap.c by avoiding an attempted dereference of a NULL conversation.
