The remote host is missing updates announced in
advisory RHSA-2006:0689.
The Linux kernel handles the basic functions of the operating system.
These new kernel packages contain fixes for the security issues described
below:
* a flaw in the SCTP support that allowed a local user to cause a denial of
service (crash) with a specific SO_LINGER value. (CVE-2006-4535, Important)
* a flaw in the hugepage table support that allowed a local user to cause a
denial of service (crash). (CVE-2005-4811, Important)
* a flaw in the mprotect system call that allowed setting write permission
for a read-only attachment of shared memory. (CVE-2006-2071, Moderate)
* a flaw in HID0[31] (en_attn) register handling on PowerPC 970 systems
that allowed a local user to cause a denial of service. (crash)
(CVE-2006-4093, Moderate)
* a flaw in the perfmon support of Itanium systems that allowed a local
user to cause a denial of service by consuming all file descriptors.
(CVE-2006-3741, Moderate)
* a flaw in the ATM subsystem. On systems with installed ATM hardware and
configured ATM support, a remote user could cause a denial of service
(panic) by accessing socket buffers memory after freeing them.
(CVE-2006-4997, Moderate)
* a flaw in the DVB subsystem. On systems with installed DVB hardware and
configured DVB support, a remote user could cause a denial of service
(panic) by sending a ULE SNDU packet with length of 0. (CVE-2006-4623, Low)
* an information leak in the network subsystem that possibly allowed a
local user to read sensitive data from kernel memory. (CVE-2006-0039, Low)
In addition, two bugfixes for the IPW-2200 wireless driver were included.
The first one ensures that wireless management applications correctly
identify IPW-2200 controlled devices, while the second fix ensures that
DHCP requests using the IPW-2200 operate correctly.
Red Hat would like to thank Olof Johansson, Stephane Eranian and Solar
Designer for reporting issues fixed in this erratum.
All Red Hat Enterprise Linux 4 users are advised to upgrade their kernels
to the packages associated with their machine architectures and
configurations as listed in this erratum.
Solution:
Please note that this update is available via
Red Hat Network. To use Red Hat Network, launch the Red
