New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

SynopsisThe remote Debian host is missing a security-related update.
DescriptionSeveral 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).
SolutionUpgrade 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.
