CVE-2010-3850

Publication date 30 November 2010

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

The ec_dev_ioctl function in net/econet/af_econet.c in the Linux kernel before 2.6.36.2 does not require the CAP_NET_ADMIN capability, which allows local users to bypass intended access restrictions and configure econet addresses via an SIOCSIFADDR ioctl call.

From the Ubuntu Security Team

Nelson Elhage discovered several problems with the Acorn Econet protocol driver. A local user could cause a denial of service via a NULL pointer dereference, escalate privileges by overflowing the kernel stack, and assign Econet addresses to arbitrary interfaces.
