  Red Hat Security Advisory 2012-0571-01

   » ‎ Packet Storm Security Advisories
  Red Hat Security Advisory 2012-0571-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way the Linux kernel's journal_unmap_buffer() function handled buffer head states. On systems that have an ext4 file system with a journal mounted, a local, unprivileged user could use this flaw to cause a denial of service. A flaw was found in the way the KVM_CREATE_IRQCHIP ioctl was handled. Calling this ioctl when at least one virtual CPU already existed could lead to a NULL pointer dereference later when the VCPU is scheduled to run. A local, unprivileged user on a KVM host could use this flaw to crash the host.

   » ‎ Packet Storm Security Advisories
  Red Hat Security Advisory 2012-0481-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Numerous reference count leaks were found in the Linux kernel's block layer I/O context handling implementation. This could allow a local, unprivileged user to cause a denial of service. A flaw was found in the Linux kernel's cifs_lookup() implementation. POSIX open during lookup should only be supported for regular files. When non-regular files pipe or other special files) are opened on lookup, it could cause a denial of service.

  Red Hat Security Advisory 2012-0480-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issue: A flaw in the xfrm6_tunnel_rcv() function in the Linux kernel's IPv6 implementation could lead to a use-after-free or double free flaw in tunnel6_rcv(). A remote attacker could use this flaw to send specially-crafted packets to a target system that is using IPv6 and also has the xfrm6_tunnel kernel module loaded, causing it to crash.

  Red Hat Security Advisory 2012-0358-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Using PCI passthrough without interrupt remapping support allowed Xen hypervisor guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting.

  Red Hat Security Advisory 2011-1479-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Using PCI passthrough without interrupt remapping support allowed Xen hypervisor guests to generate MSI interrupts and thus potentially inject traps. A privileged guest user could use this flaw to crash the host or possibly escalate their privileges on the host. The fix for this issue can prevent PCI passthrough working and guests starting. Various other issues were also addressed.

  Red Hat Security Advisory 2011-1465-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. IPv6 fragment identification value generation could allow a remote attacker to disrupt a target system's networking, preventing legitimate users from accessing its services. A signedness issue was found in the Linux kernel's CIFS implementation. A malicious CIFS server could send a specially-crafted response to a directory read request that would result in a denial of service or privilege escalation on a system that has a CIFS share mounted.

  Red Hat Security Advisory 2011-1419-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. The way IPv4 and IPv6 protocol sequence numbers and fragment IDs were generated could allow a man-in-the-middle attacker to inject packets and possibly hijack connections. Protocol sequence numbers and fragment IDs are now more random. A flaw was found in the Linux kernel's clock implementation on 32-bit, SMP systems. A local, unprivileged user could use this flaw to cause a divide error fault, resulting in a denial of service.

  Red Hat Security Advisory 2011-1163-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. This update includes backported fixes for two security issues. These issues only affected users of Red Hat Enterprise Linux 5.6 Extended Update Support, as they have already been addressed for users of Red Hat Enterprise Linux 5 in the 5.7 update, RHSA-2011:1065. A flaw was found in the way the Xen hypervisor implementation handled instruction emulation during virtual machine exits. A malicious user-space process running in an SMP guest could trick the emulator into reading a different instruction than the one that caused the virtual machine to exit. An unprivileged guest user could trigger this flaw to crash the host. This only affects systems with both an AMD x86 processor and the AMD Virtualization extensions enabled.

This could allow a remote attacker to cause a denial of service. Missing sanity checks were found in setup_arg_pages() in the Linux kernel. When making the size of the argument and environment area on the stack very large, it could trigger a BUG_ON(), resulting in a local denial of service. Various other issues were also addressed.

  Red Hat Security Advisory 2011-0833-01

   » ‎ Packet Storm Security Advisories
  Red Hat Security Advisory 2011-0833-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw in the dccp_rcv_state_process() function could allow a remote attacker to cause a denial of service, even when the socket was already closed. Multiple buffer overflow flaws were found in the Linux kernel's Management Module Support for Message Passing Technology based controllers. A local, unprivileged user could use these flaws to cause a denial of service, an information leak, or escalate their privileges. Various other issues were also addressed.
