Vulnerability Summary for CVE-2008-4113

Original release date: 09/16/2008
Last revised: 10/29/2012
Source: US-CERT/NIST

Overview

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.

Impact

CVSS Severity (version 2.0):
CVSS v2 Base Score: 4.7 (MEDIUM) (AV:L/AC:M/Au:N/C:C/I:N/A:N) (legend)
Impact Subscore: 6.9
Exploitability Subscore: 3.4
CVSS Version 2 Metrics:
Access Vector: Locally exploitable
Access Complexity: Medium
Authentication: Not required to exploit
Impact Type: Allows unauthorized disclosure of information
