Synopsis: Important: kernel security and bug fix update
Issue date: 2008-03-05
CVE Names: CVE-2006-6921 CVE-2007-5938 CVE-2007-6063
CVE-2007-6207 CVE-2007-6694
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, CVE-2007-6063: Moderate)
* 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. (CVE-2006-6921, Moderate)
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 data corruption.
* 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 panic.
* 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 directories.
* 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 driver:
* 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 kernel.
* the inability to handle kernel paging requests in "lpfc_get_scsi_buf".
* 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 causing errors.
