"A number of vulnerabilities were discovered and corrected in the Linux
2.6 kernel :

sysctl.c in the Linux kernel prior to 2.6.14.1 allows local users to
cause a Denial of Service (kernel oops) and possibly execute code by
opening an interface file in /proc/sys/net/ipv4/conf/, waiting until
the interface is unregistered, then obtaining and modifying function
pointers in memory that was used for the ctl_table (CVE-2005-2709).

Multiple vulnerabilities in versions prior to 2.6.13.2 allow local
users to cause a DoS (oops from null dereference) via fput in a 32bit
ioctl on 64-bit x86 systems or sockfd_put in the 32-bit routing_ioctl
function on 64-bit systems (CVE-2005-3044). Note that this was
previously partially corrected in MDKSA-2005:235.

Prior to 2.6.14, the kernel's atm module allows local users to cause a
DoS (panic) via certain socket calls that produce inconsistent
reference counts for loadable protocol modules (CVE-2005-3359).

A race condition in the (1) add_key, (2) request_key, and (3) keyctl
functions in the 2.6.x kernel allows local users to cause a DoS
(crash) or read sensitive kernel memory by modifying the length of a
string argument between the time that the kernel calculates the length
and when it copies the data into kernel memory (CVE-2006-0457).

Prior to 2.6.15.5, the kernel allows local users to obtain sensitive
information via a crafted XFS ftruncate call, which may return stale
data (CVE-2006-0554).

Prior to 2.6.15.5, the kernel allows local users to cause a DoS (NFS
client panic) via unknown attack vectors related to the use of
O_DIRECT (CVE-2006-0555).

Prior to an including kernel 2.6.16, sys_mbind in mempolicy.c does not
sanity check the maxnod variable before making certain computations,
which has an unknown impact and attack vectors (CVE-2006-0557).

Prior to 2.6.15.5, the kernel allows local users to cause a DoS
('endless recursive fault') via unknown attack vectors related to a
'bad elf entry address' on Intel processors (CVE-2006-0741).

Prior to 2.6.15.6, the die_if_kernel function in the kernel can allow
local users to cause a DoS by causing user faults on Itanium systems
(CVE-2006-00742).

A race in the signal-handling code which allows a process to become
unkillable when the race is triggered was also fixed.

In addition to these security fixes, other fixes have been included
such as :

  - add ich8 support

    - libata locking rewrite

    - libata clear ATA_QCFLAG_ACTIVE flag before calling the
      completion callback

  - support the Acer Aspire 5xxx/3xxx series in the acerhk
    module

    - USB storage: remove info sysfs file as it violates the
      sysfs one value per file rule

  - fix OOPS in sysfs_hash_and_remove_file()

    - pl2303 USB driver fixes; makes pl2303HX chip work
      correctly

    - fix OOPS in IPMI driver which is probably caused when
      trying to use ACPI functions when ACPI was not
      properly initialized

  - fix de_thread() racy BUG_ON()

The provided packages are patched to fix these vulnerabilities. All
users are encouraged to upgrade to these updated kernels.

To update your kernel, please follow the directions located at :

http://www.mandriva.com/en/security/kernelupdate

Please note that users using the LSI Logic 53c1030 dual-channel ultra
320 SCSI card will need to re-create their initrd images manually
prior to rebooting in order to fix a bug that prevents booting. A
future update will correct this problem. To do this, execute :

# rm /boot/initrd-2.6.12-18mdk.img # mkinitrd
/boot/initrd-2.6.12-18mdk.img 2.6.12-18mdk --with-module=mptspi"
