-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 _______________________________________________________________________ Mandriva Linux Security Advisory MDKSA-2006:059 http://www.mandriva.com/security/ _______________________________________________________________________ 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 _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-2709 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3044 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3359 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0457 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0554 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0555 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0557 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0741 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-0742 _______________________________________________________________________ Updated Packages: Mandriva Linux 2006.0: 1b218623b306f20afa82d0016d7f2b02 2006.0/RPMS/kernel-2.6.12.18mdk-1-1mdk.i586.rpm a051bd99d550490b0f878e53e68dad2f 2006.0/RPMS/kernel-BOOT-2.6.12.18mdk-1-1mdk.i586.rpm 2ed8565ec9f4bbf280ee38563cbf5ae9 2006.0/RPMS/kernel-i586-up-1GB-2.6.12.18mdk-1-1mdk.i586.rpm 93f467fbc20508c7cfcc1291c00883a4 2006.0/RPMS/kernel-i686-up-4GB-2.6.12.18mdk-1-1mdk.i586.rpm 6d682e1336225bfe35c145a9b735cee2 2006.0/RPMS/kernel-smp-2.6.12.18mdk-1-1mdk.i586.rpm e2a7bf396ef80eb13b3b49e49a632d5e 2006.0/RPMS/kernel-source-2.6-2.6.12-18mdk.i586.rpm 61e26ccfa23888a5e877137565bd2e62 2006.0/RPMS/kernel-source-stripped-2.6-2.6.12-18mdk.i586.rpm d6b3b6357df23337584dcf53d17468d3 2006.0/RPMS/kernel-xbox-2.6.12.18mdk-1-1mdk.i586.rpm 4b6b2309768ff66a5277cd0b2ad6135f 2006.0/RPMS/kernel-xen0-2.6.12.18mdk-1-1mdk.i586.rpm 6ea381cb538e6f845bdf7dd10f15b623 2006.0/RPMS/kernel-xenU-2.6.12.18mdk-1-1mdk.i586.rpm 661bf62bc99323115940fd5a088df875 2006.0/SRPMS/kernel-2.6.12.18mdk-1-1mdk.src.rpm Mandriva Linux 2006.0/X86_64: f01f7df9165bc18cecef5c306fadd288 x86_64/2006.0/RPMS/kernel-2.6.12.18mdk-1-1mdk.x86_64.rpm d1c1a1bd3a95220dbb33dc51a8bf6515 x86_64/2006.0/RPMS/kernel-BOOT-2.6.12.18mdk-1-1mdk.x86_64.rpm bab61b2878c55528c09c327e8fdbb444 x86_64/2006.0/RPMS/kernel-smp-2.6.12.18mdk-1-1mdk.x86_64.rpm 222a970d935dcd178f943e2cedb96091 x86_64/2006.0/RPMS/kernel-source-2.6-2.6.12-18mdk.x86_64.rpm 2a327a55284339a3cec137b10f55b16d x86_64/2006.0/RPMS/kernel-source-stripped-2.6-2.6.12-18mdk.x86_64.rpm 661bf62bc99323115940fd5a088df875 x86_64/2006.0/SRPMS/kernel-2.6.12.18mdk-1-1mdk.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
