SB2016112405 - Arch Linux update for wireshark-gtk

Description

This security bulletin contains information about 4 vulnerabilities.

1) Input validation error (CVE-ID: CVE-2016-9373)

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

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can create a use-after-free, triggered by network traffic or a capture file. This was addressed in epan/dissectors/packet-dcerpc-nt.c and epan/dissectors/packet-dcerpc-spoolss.c by using the wmem file scope for private strings, pass it to the affected application and perform a denial of service (DoS) attack.

2) Input validation error (CVE-ID: CVE-2016-9374)

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

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can create a buffer over-read, triggered by network traffic or a capture file. This was addressed in epan/dissectors/packet-alljoyn.c by ensuring that a length variable properly tracked the state of a signature variable, pass it to the affected application and perform a denial of service (DoS) attack.

3) Input validation error (CVE-ID: CVE-2016-9375)

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

In Wireshark 2.2.0 to 2.2.1 and 2.0.0 to 2.0.7, the DTN dissector could go into an infinite loop, triggered by network traffic or a capture file. This was addressed in epan/dissectors/packet-dtn.c by checking whether SDNV evaluation was successful.

4) Input validation error (CVE-ID: CVE-2016-9376)

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

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can create memory exhaustion, triggered by network traffic or a capture file. This was addressed in epan/dissectors/packet-openflow_v5.c by ensuring that certain length values were sufficiently large, pass it to the affected application and perform a denial of service (DoS) attack.
