This update fixes the CVEs described below.

CVE-2016-0821

Solar Designer noted that the list 'poisoning' feature, intended to mitigate the effects of bugs in list manipulation in the kernel, used poison values within the range of virtual addresses that can be allocated by user processes.

CVE-2016-1583

Jann Horn of Google Project Zero reported that the eCryptfs filesystem could be used together with the proc filesystem to cause a kernel stack overflow. If the ecryptfs-utils package was installed, local users could exploit this, via the mount.ecryptfs_private program, for denial of service (crash) or possibly for privilege escalation.

CVE-2016-2184, CVE-2016-2185, CVE-2016-2186, CVE-2016-2187, CVE-2016-3136, CVE-2016-3137, CVE-2016-3138, CVE-2016-3140

Ralf Spenneberg of OpenSource Security reported that various USB drivers do not sufficiently validate USB descriptors. This allowed a physically present user with a specially designed USB device to cause a denial of service (crash). Not all the drivers have yet been fixed.

CVE-2016-3134

The Google Project Zero team found that the netfilter subsystem does not sufficiently validate filter table entries. A user with the CAP_NET_ADMIN capability could use this for denial of service (crash) or possibly for privilege escalation.

CVE-2016-3157 / XSA-171

Andy Lutomirski discovered that the x86_64 (amd64) task switching implementation did not correctly update the I/O permission level when running as a Xen paravirtual (PV) guest. In some configurations this would allow local users to cause a denial of service (crash) or to escalate their privileges within the guest.

CVE-2016-3672

Hector Marco and Ismael Ripoll noted that it was still possible to disable Address Space Layout Randomisation (ASLR) for x86_32 (i386) programs by removing the stack resource limit. This made it easier for local users to exploit security flaws in programs that have the setuid or setgid flag set.

CVE-2016-3951

It was discovered that the cdc_ncm driver would free memory prematurely if certain errors occurred during its initialisation. This allowed a physically present user with a specially designed USB device to cause a denial of service (crash) or possibly to escalate their privileges.

CVE-2016-3955

Ignat Korchagin reported that the usbip subsystem did not check the length of data received for a USB buffer. This allowed denial of service (crash) or privilege escalation on a system configured as a usbip client, by the usbip server or by an attacker able to impersonate it over the network. A system configured as a usbip server might be similarly vulnerable to physically present users.

CVE-2016-3961 / XSA-174

Vitaly Kuznetsov of Red Hat discovered that Linux allowed use of hugetlbfs on x86 (i386 and amd64) systems even when running as a Xen paravirtualised (PV) guest, although Xen does not support huge pages.
This allowed users with access to /dev/hugepages to cause a denial of service (crash) in the guest.

CVE-2016-4482, CVE-2016-4485, CVE-2016-4486, CVE-2016-4569, CVE-2016-4578, CVE-2016-4580, CVE-2016-5243, CVE-2016-5244

Kangjie Lu reported that the USB devio, llc, rtnetlink, ALSA timer, x25, tipc, and rds facilities leaked information from the kernel stack.

CVE-2016-4565

Jann Horn of Google Project Zero reported that various components in the InfiniBand stack implemented unusual semantics for the write() operation. On a system with InfiniBand drivers loaded, local users could use this for denial of service or privilege escalation.

CVE-2016-4913

Al Viro found that the ISO9660 filesystem implementation did not correctly count the length of certain invalid name entries. Reading a directory containing such name entries would leak information from kernel memory. Users permitted to mount disks or disk images could use this to obtain sensitive information.

For Debian 7 'Wheezy', these problems have been fixed in version 3.2.81-1.

This update also fixes bug #627782, which caused data corruption in some applications running on an aufs filesystem, and includes many other bug fixes from upstream stable updates 3.2.79, 3.2.80 and 3.2.81.

For Debian 8 'Jessie', these problems will be fixed soon.
