EUVDB-ID: #VU33600

Risk: Medium

CVSSv3.1: 5.2 [AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-9374

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.
