Descriptions

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.

Desbordamiento de búfer en la función util_path_encode en udev/lib/libudev-util.c en udev antes de v1.4.1 permite a usuarios locales provocar una denegación de servicio (parada del servicio) mediante vectores que disparan una llamada con argumentos manipulados.

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.
