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). 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. For the unstable distribution (sid), these problems will be fixed soon in version 3.16.7-ckt2-1. We recommend that you upgrade your linux packages.
