ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.

A local attacker could exploit this to leverage further attacks that require knowledge of userspace memory layouts. (CVE-2009-3238) Eric Paris discovered that NFSv4 did not correctly handle file creation failures. An attacker with write access to an NFSv4 share could exploit this to create files with arbitrary mode bits, leading to privilege escalation or a loss of privacy.
