- ------------------------------------------------------------------------- Debian Security Advisory DSA-3093-1 security@debian.org http://www.debian.org/security/ Salvatore Bonaccorso December 08, 2014 http://www.debian.org/security/faq - -------------------------------------------------------------------------
Package : linux CVE ID : CVE-2014-7841 CVE-2014-8369 CVE-2014-8884 CVE-2014-9090
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).
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.
