TITLE

LM_sensors PWMConfig Insecure Temporary File Creation Vulnerability

DESCRIPTION

pwmconfig in LM_sensors before 2.9.1 creates temporary files insecurely, which allows local users to overwrite arbitrary files via a symlink attack on the fancontrol temporary file. lm_sensors Implemented in pwmconfig The script contains temporary files in a security inappropriate manner (/tmp/fancontrol) Therefore, there is a vulnerability that is subject to symbolic link attacks.pwmconfig Any file may be overwritten with the authority of the user who executes the command. The issue exists in the 'pwmconfig' script. Exploitation would most likely result in loss of data or a denial of service if critical files are overwritten in the attack. Other attacks may be possible as well. lm_sensors version 2.9.1 is reportedly affected, however, other versions may be vulnerable as well. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - -------------------------------------------------------------------------- Debian Security Advisory DSA 814-1 security@debian.org http://www.debian.org/security/ Martin Schulze September 15th, 2005 http://www.debian.org/security/faq - -------------------------------------------------------------------------- Package : lm-sensors Vulnerability : insecure temporary file Problem type : local Debian-specific: no CVE ID : CAN-2005-2672] Debian Bug : 324193 Javier Fern\xe1ndez-Sanguino Pe\xf1a discovered that a script of lm-sensors, utilities to read temperature/voltage/fan sensors, creates a temporary file with a predictable filename, leaving it vulnerable for a symlink attack. The old stable distribution (woody) is not affected by this problem. For the stable distribution (sarge) this problem has been fixed in version 2.9.1-1sarge2. For the unstable distribution (sid) this problem has been fixed in version 2.9.1-7. We recommend that you upgrade your lm-sensors package. Upgrade Instructions - -------------------- wget url will fetch the file for you dpkg -i file.deb will install the referenced file. If you are using the apt-get package manager, use the line for sources.list as given below: apt-get update will update the internal database apt-get upgrade will install corrected packages You may use an automated update by adding the resources from the footer to the proper configuration.

Background ========== lm_sensors is a software package that provides drivers for monitoring the temperatures, voltages, and fans of Linux systems with hardware monitoring devices. When the pwmconfig script of lm_sensors is executed, this would result in the file being overwritten with the rights of the user running the script, which typically is the root user. Workaround ========== There is no known workaround at this time. Resolution ========== All lm_sensors users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-apps/lm_sensors-2.9.1-r1" References ========== [ 1 ] CAN-2005-2672 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2672 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200508-19.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
