SecurityTracker URL: http://securitytracker.com/id/1015182
|
|
CVE Reference:
CVE-2005-2672
(Links to External Site)
|
Date: Nov 10 2005
|
Impact:
Modification of system information, Modification of user information, Root access via local system, User access via local system
|
Fix Available: Yes Vendor Confirmed: Yes
|
Version(s): prior to 2.9.2
|
Description:
A vulnerability was reported in lm_sensors in August 2005. A local user may be able to obtain elevated privileges.
The pwmconfig tool component creates a temporary configuration file ('/tmp/fancontrol') in an unsafe manner. A local user can create a symbolic link (symlink) from a critical file on the system to the temporary file. Then, when pwmconfig is executed, the symlinked file may be overwritten with the privileges of the pwmconfig process (typically run with root privileges). As a result, the local user can overwrite arbitrary files on the target system.
|
Impact:
A local user can gain elevated privileges on the target system.
|
Solution:
Red Hat has released a fix.
