Background ========== udev is the device manager used in the Linux 2.6 kernel series. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-fs/udev < 124-r2 >= 124-r2 Description =========== Sebastian Krahmer of SUSE discovered the following two vulnerabilities: * udev does not verify the origin of NETLINK messages properly (CVE-2009-1185). * A buffer overflow exists in the util_path_encode() function in lib/libudev-util.c (CVE-2009-1186). Impact ====== A local attacker could gain root privileges by sending specially crafted NETLINK messages to udev or cause a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All udev users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=sys-fs/udev-124-r2" References ========== [ 1 ] CVE-2009-1185 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1185 [ 2 ] CVE-2009-1186 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2009-1186 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200904-18.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.
