Debian DLA-412-1 : linux-2.6 security update

Description

This update fixes the CVEs described below. CVE-2015-7566 Ralf Spenneberg of OpenSource Security reported that the visor driver crashes when a specially crafted USB device without bulk-out endpoint is detected. CVE-2015-8767 An SCTP denial of service was discovered which can be triggered by a local attacker during a heartbeat timeout event after the 4-way handshake. CVE-2015-8785 It was discovered that local users permitted to write to a file on a FUSE filesystem could cause a denial of service (unkillable loop in the kernel). CVE-2016-0723 A use-after-free vulnerability was discovered in the TIOCGETD ioctl. A local attacker could use this flaw for denial of service. CVE-2016-2069 Andy Lutomirski discovered a race condition in flushing of the TLB when switching tasks. On an SMP system this could possibly lead to a crash, information leak or privilege escalation. For the oldoldstable distribution (squeeze), these problems have been fixed in version 2.6.32-48squeeze19. Additionally, this version includes upstream stable update 2.6.32.70. This is the final update to the linux-2.6 package for squeeze. For the oldstable distribution (wheezy), these problems will be fixed soon. For the stable distribution (jessie), CVE-2015-7566, CVE-2015-8767 and CVE-2016-0723 were fixed in linux version 3.16.7-ckt20-1+deb8u3 and the remaining problems will be fixed soon. NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
