Synopsis
Two errors in udev allow for a local root compromise and a Denial of
Service.
2.
Impact Information
Background
udev is the device manager used in the Linux 2.6 kernel series.
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.
3.
Resolution Information
Workaround
There is no known workaround at this time.
Resolution
All udev users should upgrade to the latest version:
Code Listing 3.1: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-fs/udev-124-r2"
|
