 Mandriva Linux Security Advisory                         MDKSA-2006:059

 Package : kernel
 Date    : March 22, 2006
 Affected: 2006.0
 _______________________________________________________________________
 
 Problem Description:
 
 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
