| Description: | 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 flaw was found in the Realtek r8169 Ethernet driver in the Linux
kernel. pci_unmap_single() presented a memory leak that could lead to IOMMU
space exhaustion and a system crash. An attacker on the local network could
trigger this flaw by using jumbo frames for large amounts of network
traffic. (CVE-2009-3613, Important)
* NULL pointer dereference flaws were found in the r128 driver in the Linux
kernel. Checks to test if the Concurrent Command Engine state was
initialized were missing in private IOCTL functions. An attacker could use
these flaws to cause a local denial of service or escalate their
privileges. (CVE-2009-3620, Important)
* an information leak was found in the Linux kernel. On AMD64 systems,
32-bit processes could access and read certain 64-bit registers by
temporarily switching themselves to 64-bit mode. (CVE-2009-2910, Moderate)
* the unix_stream_connect() function in the Linux kernel did not check if a
UNIX domain socket was in the shutdown state. This could lead to a
deadlock. A local, unprivileged user could use this flaw to cause a denial
of service. (CVE-2009-3621, Moderate)
This update also fixes the following bugs:
* an iptables rule with the recent module and a hit count value greater
than the ip_pkt_list_tot parameter (the default is 20), did not have any
effect over packets, as the hit count could not be reached. (BZ#529306)
* in environments that use dual-controller storage devices with the cciss
driver, Device-Mapper Multipath maps could not be detected and configured,
due to the cciss driver not exporting the bus attribute via sysfs. This
attribute is now exported. (BZ#529309)
* the kernel crashed with a divide error when a certain joystick was
attached. (BZ#532027)
* a bug in the mptctl_do_mpt_command() function in the mpt driver may have
resulted in crashes during boot on i386 systems with certain adapters using
the mpt driver, and also running the hugemem kernel. (BZ#533798)
* on certain hardware, the igb driver was unable to detect link statuses
correctly. This may have caused problems for network bonding, such as
failover not occurring. (BZ#534105)
* the RHSA-2009:1024 update introduced a regression. After updating to Red
Hat Enterprise Linux 4.8 and rebooting, network links often failed to be
brought up for interfaces using the forcedeth driver. 'no link during
initialization' messages may have been logg ...
