Linux Kernel fib6_add_rt2node denial of service

linux-cve20134125-dos (85645) The risk level is classified as MediumMedium Risk

Description:

Linux Kernel is vulnerable to a denial of service, caused by the improper handling of Router Advertisement (RA) messages by the fib6_add_rt2node function. A remote attacker could exploit this vulnerability using a specially-crafted sequence of messages to cause the system to crash.

*CVSS:

Base Score: 5.4
  Access Vector: Network
  Access Complexity: High
  Authentication: None
  Confidentiality Impact: None
  Integrity Impact: None
  Availability Impact: Complete
 
Temporal Score: 4
  Exploitability: Unproven
  Remediation Level: Official-Fix
  Report Confidence: Confirmed

Consequences:

Denial of Service

Remedy:

Apply the patch for this vulnerability, available from the Linux Kernel GIT Repository. See References.

  • Linux Kernel GIT Repository: only static routes qualify for equal cost multipathing.
  • Red Hat Bugzilla Bug 984664: CVE-2013-4125 kernel: ipv6: BUG_ON in fib6_add_rt2node().
  • BID-61166: Linux Kernel CVE-2013-4125 Remote Denial of Service Vulnerability
  • CVE-2013-4125: The fib6_add_rt2node function in net/ipv6/ip6_fib.c in the IPv6 stack in the Linux kernel through 3.10.1 does not properly handle Router Advertisement (RA) messages in certain circumstances involving three routes that initially qualified for membership in an ECMP route set until a change occurred for one of the first two routes, which allows remote attackers to cause a denial of service (system crash) via a crafted sequence of messages.
