Junos RDP Crash Vulnerability

Published: 2014-06-16 04:34:19

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

Detection Type:
Linux Distribution Package

Solution Type:
Vendor Patch

Summary:
RDP crash when receiving BGP UPDATE with malformed inetflow prefix.

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

Technical Details:
Receipt of a BGP UPDATE message containing a crafted flow specification NLRI may cause RPD to crash. The update creates an invalid inetflow prefix which causes the RPD process to allocate memory until it reaches its assigned memory limit.

Impact:
After trying to exceed the process memory limit, RPD will crash and restart. The system recovers after the crash, however a constant stream of malformed updates could cause an extended outage.

Affected Versions:
Junos OS 10.0, 10.4, 11.4, 12.1 and 12.2.

Recommendations:
New builds of Junos OS software are available from Juniper. As a workaround disable the propagation of flow-specification NLRI messages via BGP by removing the flow configuration option from protocols bgp ... family inet.

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".
