The remote Scientific Linux host is missing one or more security
These updated packages fix the following security issues :
- a flaw in the hypervisor for hosts running on Itanium
architectures allowed an Intel VTi domain to read
arbitrary physical memory from other Intel VTi domains,
which could make information available to unauthorized
users. (CVE-2007-6207, Important)
- two buffer overflow flaws were found in ISDN subsystem.
A local unprivileged user could use these flaws to cause
a denial of service. (CVE-2007-5938: Important,
- a possible NULL pointer dereference was found in the
subsystem used for showing CPU information, as used by
CHRP systems on PowerPC architectures. This may have
allowed a local unprivileged user to cause a denial of
service (crash). (CVE-2007-6694, Moderate)
- a flaw was found in the handling of zombie processes. A
local user could create processes that would not be
properly reaped, possibly causing a denial of service.
As well, these updated packages fix the following bugs :
- a bug was found in the Linux kernel audit subsystem.
When the audit daemon was setup to log the execve system
call with a large number of arguments, the kernel could
run out of memory, causing a kernel panic.
- on IBM System z architectures, using the IBM Hardware
Management Console to toggle IBM FICON channel path ids
(CHPID) caused a file ID miscompare, possibly causing
- when running the IA-32 Execution Layer (IA-32EL) or a
Java VM on Itanium architectures, a bug in the address
translation in the hypervisor caused the wrong address
to be registered, causing Dom0 to hang.
- on Itanium architectures, frequent Corrected Platform
Error errors may have caused the hypervisor to hang.
- when enabling a CPU without hot plug support, routines
for checking the presence of the CPU were missing. The
CPU tried to access its own resources, causing a kernel
- after updating to kernel-2.6.18-53.el5, a bug in the
CCISS driver caused the HP Array Configuration Utility
CLI to become unstable, possibly causing a system hang,
or a kernel panic.
- a bug in NFS directory caching could have caused
different hosts to have different views of NFS
- on Itanium architectures, the Corrected Machine Check
Interrupt masked hot-added CPUs as disabled.
- when running Oracle database software on the Intel 64
and AMD64 architectures, if an SGA larger than 4GB was
created, and had hugepages allocated to it, the
hugepages were not freed after database shutdown.
- in a clustered environment, when two or more NFS clients
had the same logical volume mounted, and one of them
modified a file on the volume, NULL characters may have
been inserted, possibly causing data corruption.
These updated packages resolve several severe issues in the lpfc
- a system hang after LUN discovery.
- a general fault protection, a NULL pointer dereference,
or slab corruption could occur while running a debug on
- the inability to handle kernel paging requests in
- erroneous structure references caused certain FC
discovery routines to reference and change
'lpfc_nodelist' structures, even after they were freed.
- the lpfc driver failed to interpret certain fields
correctly, causing tape backup software to fail. Tape
drives reported 'Illegal Request'.
- the lpfc driver did not clear structures correctly,
resulting in SCSI I/Os being rejected by targets, and
