ISS X-Force Database: kernel-sctpgetsockopthmac-info-disclosure(45188): Linux Kernel sctp_getsockopt_hmac

Linux Kernel sctp_getsockopt_hmac_ident information disclosure

kernel-sctpgetsockopthmac-info-disclosure (45188)

Low Risk

Description:

Linux Kernel could allow a local attacker to obtain sensitive information, caused by an error in the sctp_getsockopt_hmac_ident function within the Stream Control Transmission Protocol (sctp) implementation. If the SCTP-AUTH extension is enabled, a local attacker could send a specially-crafted SCTP_HMAC_IDENT IOCTL request to obtain sensitive information.

*CVSS:

Base Score:	1.9
Access Vector:	Local
Access Complexity:	Medium
Authentication:	None
Confidentiality Impact:	Partial
Integrity Impact:	None
Availability Impact:	None

Temporal Score:	1.5
Exploitability:	Proof-of-Concept
Remediation Level:	Official-Fix
Report Confidence:	Confirmed

Consequences:

Obtain Information

Remedy:

Upgrade to the latest version of Linux Kernel (2.6.26.4 or later), available from The Linux Kernel Archives Web site. See References.

CVE-2008-4113: The sctp_getsockopt_hmac_ident function in net/sctp/socket.c in the Stream Control Transmission Protocol (sctp) implementation in the Linux kernel before 2.6.26.4, when the SCTP-AUTH extension is enabled, relies on an untrusted length value to limit copying of data from kernel memory, which allows local users to obtain sensitive information via a crafted SCTP_HMAC_IDENT IOCTL request involving the sctp_getsockopt function.
