Title: | USN-2417-1 -- Linux kernel vulnerabilities | ||
Description: | Nadav Amit reported that the KVM (Kernel Virtual Machine) mishandles noncanonical addresses when emulating instructions that change the rip (Instruction Pointer). A guest user with access to I/O or the MMIO can use this flaw to cause a denial of service (system crash) of the guest. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-3647">CVE-2014-3647</a>) A flaw was discovered with the handling of the invept instruction in the KVM (Kernel Virtual Machine) subsystem of the Linux kernel. An unprivileged guest user could exploit this flaw to cause a denial of service (system crash) on the guest. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-3646">CVE-2014-3646</a>) A flaw was discovered with invept instruction support when using nested EPT in the KVM (Kernel Virtual Machine). An unprivileged guest user could exploit this flaw to cause a denial of service (system crash) on the guest. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-3645">CVE-2014-3645</a>) Lars Bull reported a race condition in the PIT (programmable interrupt timer) emulation in the KVM (Kernel Virtual Machine) subsystem of the Linux kernel. A local guest user with access to PIT i/o ports could exploit this flaw to cause a denial of service (crash) on the host. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-3611">CVE-2014-3611</a>) Lars Bull and Nadav Amit reported a flaw in how KVM (the Kernel Virtual Machine) handles noncanonical writes to certain MSR registers. A privileged guest user can exploit this flaw to cause a denial of service (kernel panic) on the host. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-3610">CVE-2014-3610</a>) A flaw in the handling of malformed ASCONF chunks by SCTP (Stream Control Transmission Protocol) implementation in the Linux kernel was discovered. A remote attacker could exploit this flaw to cause a denial of service (system crash). (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-3673">CVE-2014-3673</a>) A flaw in the handling of duplicate ASCONF chunks by SCTP (Stream Control Transmission Protocol) implementation in the Linux kernel was discovered. A remote attacker could exploit this flaw to cause a denial of service (panic). (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-3687">CVE-2014-3687</a>) It was discovered that excessive queuing by SCTP (Stream Control Transmission Protocol) implementation in the Linux kernel can cause memory pressure. A remote attacker could exploit this flaw to cause a denial of service. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-3688">CVE-2014-3688</a>) A flaw was discovered in how the Linux kernel's KVM (Kernel Virtual Machine) subsystem handles the CR4 control register at VM entry on Intel processors. A local host OS user can exploit this to cause a denial of service (kill arbitrary processes, or system disruption) by leveraging /dev/kvm access. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-3690">CVE-2014-3690</a>) Don Bailey discovered a flaw in the LZO decompress algorithm used by the Linux kernel. An attacker could exploit this flaw to cause a denial of service (memory corruption or OOPS). (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-4608">CVE-2014-4608</a>) It was discovered the Linux kernel's implementation of IPv6 did not properly validate arguments in the ipv6_select_ident function. A local user could exploit this flaw to cause a denial of service (system crash) by leveraging tun or macvtap device access. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-7207">CVE-2014-7207</a>) Andy Lutomirski discovered that the Linux kernel was not checking the CAP_SYS_ADMIN when remounting filesystems to read-only. A local user could exploit this flaw to cause a denial of service (loss of writability). (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-7975">CVE-2014-7975</a>) | ||
