Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2016-4084)

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

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (integer overflow and application crash) via a crafted packet that triggers an unexpected array size.


2) Input validation error (CVE-ID: CVE-2016-4083)

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

epan/dissectors/packet-mswsp.c in the MS-WSP dissector in Wireshark 2.0.x before 2.0.3 does not ensure that data is available before array allocation, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.


3) Input validation error (CVE-ID: CVE-2016-4077)

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

The vulnerability exists due to insufficient validation of user-supplied input. A remote attacker can cause a denial of service (use-after-free and application crash) via a crafted packet.


4) Improper access control (CVE-ID: CVE-2016-4076)

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

epan/dissectors/packet-ncp2222.inc in the NCP dissector in Wireshark 2.0.x before 2.0.3 does not properly initialize memory for search patterns, which allows remote attackers to cause a denial of service (application crash) via a crafted packet.
