Mandriva Linux Security Advisory 2009-103

Mandriva Linux Security Advisory 2009-103
Posted Dec 3, 2009
Authored by Mandriva | Site mandriva.com

Mandriva Linux Security Advisory 2009-103 - Security vulnerabilities have been identified and fixed in udev. udev before 1.4.1 does not verify whether a NETLINK message originates from kernel space, which allows local users to gain privileges by sending a NETLINK message from user space. Buffer overflow in the util_path_encode function in udev/lib/libudev-util.c in udev before 1.4.1 allows local users to cause a denial of service (service outage) via vectors that trigger a call with crafted arguments. The updated packages have been patched to prevent this. Packages for 2008.0 are being provided due to extended support for Corporate products.

Package : udev
Date : December 3, 2009
Affected: 2008.0
_______________________________________________________________________

Problem Description:

Security vulnerabilities have been identified and fixed in udev.

udev before 1.4.1 does not verify whether a NETLINK message originates
from kernel space, which allows local users to gain privileges by
sending a NETLINK message from user space (CVE-2009-1185).

Buffer overflow in the util_path_encode function in
udev/lib/libudev-util.c in udev before 1.4.1 allows local users to
cause a denial of service (service outage) via vectors that trigger
a call with crafted arguments (CVE-2009-1186).

The updated packages have been patched to prevent this.

Update:

Packages for 2008.0 are being provided due to extended support for
Corporate products.
