Description:
alert7 has reported two vulnerabilities in the Linux kernel, which can be exploited by malicious, local users to gain escalated privileges.
Input validation errors in the raw device and pktcdvd block device ioctl handlers (raw_ioctl() and pkt_ioctl() functions) can be exploited to corrupt kernel memory via specially crafted arguments passed to the ioctl_by_bdev() function.
Successful exploitation allows execution of arbitrary code with kernel level privileges, but requires that the user can read the affected block device.
Solution:
Update to version 2.6.11.10.
