ISS X-Force Database: linux-kernel-sctpgetsockopt-dos(43559): Linux kernel sctp_getsockopt_local_addrs

Linux kernel sctp_getsockopt_local_addrs_old() denial of service

linux-kernel-sctpgetsockopt-dos (43559)

Medium Risk

Description:

The Linux kernel is vulnerable to a denial of service, caused by an integer overflow in the sctp_getsockopt_local_addrs_old function in net/sctp/socket.c. A local attacker could exploit this vulnerability by setting an overly large addr_num field in an sctp_getaddrs_old data structure to consume all available resources and cause the system to stop responding.

*CVSS:

Base Score:	4.9
Access Vector:	Local
Access Complexity:	Low
Authentication:	None
Confidentiality Impact:	None
Integrity Impact:	None
Availability Impact:	Complete

Temporal Score:	3.6
Exploitability:	Unproven
Remediation Level:	Official-Fix
Report Confidence:	Confirmed

Consequences:

Denial of Service

Remedy:

Upgrade to the latest version of the Linux kernel (2.6.25.10 or later), available from The Linux Kernel Archives Web site. See References.

For other distributions:
Apply the appropriate update for your system. See References.
