Package : linux
CVE ID : CVE-2015-8956 CVE-2016-5195 CVE-2016-7042 CVE-2016-7425
Debian Bug : 831014
Several vulnerabilities have been discovered in the Linux kernel that
may lead to a privilege escalation, denial of service or information
leaks.
CVE-2015-8956
It was discovered that missing input sanitising in RFCOMM Bluetooth
socket handling may result in denial of service or information leak.
CVE-2016-5195
It was discovered that a race condition in the memory management
code can be used for local privilege escalation.
CVE-2016-7042
Ondrej Kozina discovered that incorrect buffer allocation in the
proc_keys_show() function may result in local denial of service.
CVE-2016-7425
Marco Grassi discovered a buffer overflow in the arcmsr SCSI driver
which may result in local denial of service, or potentially,
arbitrary code execution.
Additionally this update fixes a regression introduced in DSA-3616-1
causing iptables performance issues (cf. Debian Bug #831014).
For the stable distribution (jessie), these problems have been fixed in
version 3.16.36-1+deb8u2.
We recommend that you upgrade your linux packages.
