| Descripción: | Summary:
The remote host is missing an update for the 'kernel'
package(s) announced via the referenced advisory.
Vulnerability Insight:
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
This update fixes the following security issues:
* An integer overflow flaw in ib_uverbs_poll_cq() could allow a local,
unprivileged user to cause a denial of service or escalate their
privileges. (CVE-2010-4649, Important)
* A race condition in the way new InfiniBand connections were set up could
allow a remote user to cause a denial of service. (CVE-2011-0695,
Important)
* A flaw in the Stream Control Transmission Protocol (SCTP) implementation
could allow a remote attacker to cause a denial of service if the sysctl
'net.sctp.addip_enable' variable was turned on (it is off by default).
(CVE-2011-1573, Important)
* Flaws in the AGPGART driver implementation when handling certain IOCTL
commands could allow a local, unprivileged user to cause a denial of
service or escalate their privileges. (CVE-2011-1745, CVE-2011-2022,
Important)
* An integer overflow flaw in agp_allocate_memory() could allow a local,
unprivileged user to cause a denial of service or escalate their
privileges. (CVE-2011-1746, Important)
* A flaw allowed napi_reuse_skb() to be called on VLAN (virtual LAN)
packets. An attacker on the local network could trigger this flaw by
sending specially-crafted packets to a target system, possibly causing a
denial of service. (CVE-2011-1576, Moderate)
* An integer signedness error in next_pidmap() could allow a local,
unprivileged user to cause a denial of service. (CVE-2011-1593, Moderate)
* A flaw in the way the Xen hypervisor implementation handled CPUID
instruction emulation during virtual machine exits could allow an
unprivileged guest user to crash a guest. This only affects systems that
have an Intel x86 processor with the Intel VT-x extension enabled.
(CVE-2011-1936, Moderate)
* A flaw in inet_diag_bc_audit() could allow a local, unprivileged user to
cause a denial of service (infinite loop). (CVE-2011-2213, Moderate)
* A missing initialization flaw in the XFS file system implementation
could lead to an information leak. (CVE-2011-0711, Low)
* A flaw in ib_uverbs_poll_cq() could allow a local, unprivileged user to
cause an information leak. (CVE-2011-1044, Low)
* A missing validation check was found in the signals implementation. A
local, unprivileged user could use this flaw to send signals via the
sigqueueinfo system call, with the si_code set to SI_TKILL and with spoofed
process and user IDs, to other processes. Note: This flaw does not allow
existing permission check ...
