| 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:
* A heap overflow flaw was found in the Linux kernel's Transparent
Inter-Process Communication protocol (TIPC) implementation. A local,
unprivileged user could use this flaw to escalate their privileges.
(CVE-2010-3859, Important)
* Missing sanity checks were found in gdth_ioctl_alloc() in the gdth driver
in the Linux kernel. A local user with access to '/dev/gdth' on a 64-bit
system could use these flaws to cause a denial of service or escalate their
privileges. (CVE-2010-4157, Moderate)
* A NULL pointer dereference flaw was found in the Bluetooth HCI UART
driver in the Linux kernel. A local, unprivileged user could use this flaw
to cause a denial of service. (CVE-2010-4242, Moderate)
* A flaw was found in the Linux kernel's garbage collector for AF_UNIX
sockets. A local, unprivileged user could use this flaw to trigger a
denial of service (out-of-memory condition). (CVE-2010-4249, Moderate)
* Missing initialization flaws were found in the Linux kernel. A local,
unprivileged user could use these flaws to cause information leaks.
(CVE-2010-3876, CVE-2010-4072, CVE-2010-4073, CVE-2010-4075, CVE-2010-4080,
CVE-2010-4083, CVE-2010-4158, Low)
Red Hat would like to thank Alan Cox for reporting CVE-2010-4242, Vegard
Nossum for reporting CVE-2010-4249, Vasiliy Kulikov for reporting
CVE-2010-3876, Kees Cook for reporting CVE-2010-4072, and Dan Rosenberg for
reporting CVE-2010-4073, CVE-2010-4075, CVE-2010-4080, CVE-2010-4083, and
CVE-2010-4158.
This update also fixes the following bugs:
* A flaw was found in the Linux kernel where, if used in conjunction with
another flaw that can result in a kernel Oops, could possibly lead to
privilege escalation. It does not affect Red Hat Enterprise Linux 4 as the
sysctl panic_on_oops variable is turned on by default. However, as a
preventive measure if the variable is turned off by an administrator, this
update addresses the issue. Red Hat would like to thank Nelson Elhage for
reporting this vulnerability. (BZ#659568)
* On Intel I/O Controller Hub 9 (ICH9) hardware, jumbo frame support is
achieved by using page-based sk_buff buffers without any packet split. The
entire frame data is copied to the page(s) rather than some to the
skb->data area and some to the page(s) when performing a typical
packet-split. T ...
