Summary

The remote host is missing an update for the 'kernel' package(s) announced via the referenced advisory.

Insight

Insight

The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issue: * It was found that the data_len parameter of the sock_alloc_send_pskb() function in the Linux kernel's networking implementation was not validated before use. A local user with access to a TUN/TAP virtual interface could use this flaw to crash the system or, potentially, escalate their privileges. Note that unprivileged users cannot access TUN/TAP devices until the root user grants them access. (CVE-2012-2136, Important) This update also fixes various bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. Users should upgrade to these updated packages, which contain backported patches to correct this issue, and fix the bugs noted in the Technical Notes. The system must be rebooted for this update to take effect.
