Wireshark Multiple DoS Vulnerabilities Mar17 (MAC OS X)

Published: 2017-03-07 07:50:20
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:N/I:N/A:C

Summary:
This host is installed with Wireshark and is prone to multiple denial of service vulnerabilities.

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
Multiple flaws exist due to, - An improper validation of record sizes in 'wiretap/netscaler.c' script. - An improper incrementing of certain sequence value in 'epan/dissectors/packet-rtmpt.c' script. - An improper validation of the relationships between lengths and offsets in 'wiretap/k12.c' script. - An error related to constraining packet lateness in 'pan/dissectors/packet-iax2.c' script. - An improper validation of the capability length in 'epan/dissectors/packet-wsp.c' script. - In 'epan/dissectors/packet-ldss.c' memory was not allocated for a certain data structure. - If the packet size field in a packet header is null, the offset to read from will not advance, causing continuous attempts to read the same zero length packet.

Impact:
Successful exploitation will allow remote attackers to cause the application to enter an infinite loop and consume excessive CPU resources, resulting in denial-of-service conditions.

Affected Versions:
Wireshark version 2.2.0 to 2.2.4 and 2.0.0 to 2.0.10 on Mac OS X

Recommendations:
Upgrade to Wireshark version 2.2.5 or 2.0.11 or later.

Solution Type:
Vendor Patch

Detection Type:
Executable

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
