Description
This security bulletin contains information about 1 security vulnerability.
1) Input validation error (CVE-ID: CVE-2010-3850)
The vulnerability allows a local user to corrupt data.
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.
