Title: USN-2448-2 -- Linux kernel regression
Description: USN-2448-1 fixed vulnerabilities in the Linux kernel. Due to an unrelated regression TCP Throughput drops to zero for several drivers after upgrading. This update fixes the problem. We apologize for the inconvenience. Original advisory details: An information leak in the Linux kernel was discovered that could leak the high 16 bits of the kernel stack address on 32-bit Kernel Virtual Machine (KVM) paravirt guests. A user in the guest OS could exploit this leak to obtain information that could potentially be used to aid in attacking the kernel. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-8134">CVE-2014-8134</a>) Rabin Vincent, Robert Swiecki, Russell King discovered that the ftrace subsystem of the Linux kernel does not properly handle private syscall numbers. A local user could exploit this flaw to cause a denial of service (OOPS). (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-7826">CVE-2014-7826</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>) Rabin Vincent, Robert Swiecki, Russell Kinglaw discovered a flaw in how the perf subsystem of the Linux kernel handles private systecall numbers. A local user could exploit this to cause a denial of service (OOPS) or bypass ASLR protections via a crafted application. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-7825">CVE-2014-7825</a>) Andy Lutomirski discovered a flaw in how the Linux kernel handles pivot_root when used with a chroot directory. A local user could exploit this flaw to cause a denial of service (mount-tree loop). (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-7970">CVE-2014-7970</a>) Dmitry Monakhov discovered a race condition in the ext4_file_write_iter function of the Linux kernel&#39;s ext4 filesystem. A local user could exploit this flaw to cause a denial of service (file unavailability). (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-8086">CVE-2014-8086</a>) The KVM (kernel virtual machine) subsystem of the Linux kernel miscalculates the number of memory pages during the handling of a mapping failure. A guest OS user could exploit this to cause a denial of service (host OS page unpinning) or possibly have unspecified other impact by leveraging guest OS privileges. (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-8369">CVE-2014-8369</a>) Andy Lutomirski discovered that the Linux kernel does not properly handle faults associated with the Stack Segment (SS) register on the x86 architecture. A local attacker could exploit this flaw to cause a denial of service (panic). (<a href="http://people.ubuntu.com/~ubuntu-security/cve/CVE-2014-9090">CVE-2014-9090</a>)
