ISS X-Force Database: linux-kernel-sctp-initack-dos(45773): Linux kernel SCTP INIT-ACK denial of service

Linux kernel SCTP INIT-ACK denial of service

linux-kernel-sctp-initack-dos (45773)

Low Risk

Description:

The Linux kernel is vulnerable to a denial of service, caused by an error in stream control transmission protocol (SCTP). By sending an INIT-ACK request with the SupportedExtensions parameter set, a remote attacker could cause a kernel panic when the T1-Init timer expires.

*CVSS:

Base Score:	7.8
Access Vector:	Network
Access Complexity:	Low
Authentication:	None
Confidentiality Impact:	None
Integrity Impact:	None
Availability Impact:	Complete

Temporal Score:	5.8
Exploitability:	Unproven
Remediation Level:	Official-Fix
Report Confidence:	Confirmed

Consequences:

Denial of Service

Remedy:

Upgrade to the latest version of the Linux kernel (2.6.27-rc6-git6 or later), available from The Linux Kernel Archives Web site. See References.

BID-31634: Linux Kernel SCTP INIT-ACK AUTH Extension Remote Denial of Service Vulnerability
CVE-2008-4576: sctp in Linux kernel before 2.6.25.18 allows remote attackers to cause a denial of service (OOPS) via an INIT-ACK that states the peer does not support AUTH, which causes the sctp_process_init function to clean up active transports and triggers the OOPS when the T1-Init timer expires.
