Description

Debian has issued an update for the kernel. This fixes some security issues and vulnerabilities, which can be exploited by malicious, local users to cause a DoS (Denial of Service), bypass certain security restrictions, or gain escalated privileges.

For more information:
SA23955
SA26934
SA26935

This also fixes a security issue in the JFFS2 file system, where legacy modes were not correctly saved to the medium when POSIX ACL was enabled or ACL was set. This could result in insecure file permissions after a remount of an affected file system.


Solution
Apply updated packages.
