Debian DSA-3093-1 : linux - security update

medium Nessus Plugin ID 79807
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or privilege escalation :

- CVE-2014-7841 Liu Wei of Red Hat discovered that a SCTP server doing ASCONF will panic on malformed INIT chunks by triggering a NULL pointer dereference.

- CVE-2014-8369 A flaw was discovered in the way iommu mapping failures were handled in the kvm_iommu_map_pages() function in the Linux kernel. A guest OS user could exploit this flaw to cause a denial of service (host OS memory corruption) or possibly have other unspecified impact on the host OS.

- CVE-2014-8884 A stack-based buffer overflow flaw was discovered in the TechnoTrend/Hauppauge DEC USB driver. A local user with write access to the corresponding device could use this flaw to crash the kernel or, potentially, elevate their privileges.

- CVE-2014-9090 Andy Lutomirski discovered that the do_double_fault function in arch/x86/kernel/traps.c in the Linux kernel did not properly handle faults associated with the Stack Segment (SS) segment register, which allows local users to cause a denial of service (panic).


Upgrade the linux packages.

For the stable distribution (wheezy), these problems have been fixed in version 3.2.63-2+deb7u2. This update also includes fixes for regressions introduced by previous updates.
