Vulnerability Summary for CVE-2008-3833

Original release date: 10/03/2008
Last revised: 08/21/2013
Source: US-CERT/NIST

Overview

The generic_file_splice_write function in fs/splice.c in the Linux kernel before 2.6.19 does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by splicing into an inode in order to create an executable file in a setgid directory, a different vulnerability than CVE-2008-4210.

Impact

CVSS Severity (version 2.0):
CVSS v2 Base Score: 4.9 (MEDIUM) (AV:L/AC:L/Au:N/C:C/I:N/A:N) (legend)
Impact Subscore: 6.9
Exploitability Subscore: 3.9
CVSS Version 2 Metrics:
Access Vector: Locally exploitable
Access Complexity: Low
Authentication: Not required to exploit
Impact Type: Allows unauthorized disclosure of information
