Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200904-18 (udev: Multiple vulnerabilities)

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.

Solution

All udev users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose '>=sys-fs/udev-124-r2'
