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.
