Debian DLA-412-1 : linux-2.6 security update
Medium Nessus Plugin ID 88600
SynopsisThe remote Debian host is missing a security update.
DescriptionThis update fixes the CVEs described below.
Ralf Spenneberg of OpenSource Security reported that the visor driver crashes when a specially crafted USB device without bulk-out endpoint is detected.
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.
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).
A use-after-free vulnerability was discovered in the TIOCGETD ioctl. A local attacker could use this flaw for denial of service.
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 188.8.131.52. 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.
