_______________________________________________________________________ Mandriva Linux Security Advisory MDKSA-2006:151 http://www.mandriva.com/security/ _______________________________________________________________________ Package : kernel Date : August 25, 2006 Affected: 2006.0 _______________________________________________________________________ Problem Description: A number of vulnerabilities were discovered and corrected in the Linux 2.6 kernel: Prior to and including 2.6.16-rc2, when running on x86_64 systems with preemption enabled, local users can cause a DoS (oops) via multiple ptrace tasks that perform single steps (CVE-2006-1066). Prior to 2.6.16, a directory traversal vulnerability in CIFS could allow a local user to escape chroot restrictions for an SMB-mounted filesystem via "..\\" sequences (CVE-2006-1863). Prior to 2.6.16, a directory traversal vulnerability in smbfs could allow a local user to escape chroot restrictions for an SMB-mounted filesystem via "..\\" sequences (CVE-2006-1864). Prior to to 2.6.16.23, SCTP conntrack in netfilter allows remote attackers to cause a DoS (crash) via a packet without any chunks, causing a variable to contain an invalid value that is later used to dereference a pointer (CVE-2006-2934). The dvd_read_bca function in the DVD handling code assigns the wrong value to a length variable, which could allow local users to execute arbitrary code via a crafted USB storage device that triggers a buffer overflow (CVE-2006-2935). Prior to 2.6.17, the ftdi_sio driver could allow local users to cause a DoS (memory consumption) by writing more data to the serial port than the hardware can handle, causing the data to be queued (CVE-2006-2936). The 2.6 kernel, when using both NFS and EXT3, allowed remote attackers to cause a DoS (file system panic) via a crafted UDP packet with a V2 lookup procedure that specifies a bad file handle (inode number), triggering an error and causing an exported directory to be remounted read-only (CVE-2006-3468). The 2.6 kernel's SCTP was found to cause system crashes and allow for the possibility of local privilege escalation due to a bug in the get_user_iov_size() function that doesn't properly handle overflow when calculating the length of iovec (CVE-2006-3745). The provided packages are patched to fix these vulnerabilities. All users are encouraged to upgrade to these updated kernels immediately and reboot to effect the fixes. In addition to these security fixes, other fixes have been included such as: - added support for new devices: o Testo products in usb-serial o ATI SB600 IDE o ULI M-1573 south Bridge o PATA and SATA support for nVidia MCP55, MCP61, MCP65, and AMD CS5536 o Asus W6A motherboard in snd-hda-intel o bcm 5780 - fixed ip_gre module unload OOPS - enabled opti621 driver for x86 and x86_64 - fixed a local DoS introduced by an imcomplete fix for CVE-2006-2445 - updated to Xen 3.0.1 with selected fixes - enable hugetlbfs To update your kernel, please follow the directions located at: http://www.mandriva.com/en/security/kernelupdate _______________________________________________________________________ References: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-1066 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-1863 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-1864 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2934 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2935 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2936 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3468 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-3745 _______________________________________________________________________ Updated Packages: Mandriva Linux 2006.0: 9b4811892823bfa6ddfa648f029ee500 2006.0/RPMS/kernel-2.6.12.25mdk-1-1mdk.i586.rpm 27e6afeac2d98e07cd8a16d2ffa8de28 2006.0/RPMS/kernel-BOOT-2.6.12.25mdk-1-1mdk.i586.rpm dcd2a1843a5f56c286a0e6270c7b1d79 2006.0/RPMS/kernel-i586-up-1GB-2.6.12.25mdk-1-1mdk.i586.rpm 477b78d6836d03484a58720f2137e506 2006.0/RPMS/kernel-i686-up-4GB-2.6.12.25mdk-1-1mdk.i586.rpm ab1f7540dbfd41f469f4931a710dbe95 2006.0/RPMS/kernel-smp-2.6.12.25mdk-1-1mdk.i586.rpm ed246f8b552bb26bb8e89c0c0842bbe9 2006.0/RPMS/kernel-source-2.6.12.25mdk-1-1mdk.i586.rpm acb15b08ed7f7d2ad3747c555a07b401 2006.0/RPMS/kernel-source-stripped-2.6.12.25mdk-1-1mdk.i586.rpm ede19a2f7dd7b715c58e9c61ee1c3359 2006.0/RPMS/kernel-xbox-2.6.12.25mdk-1-1mdk.i586.rpm 848a9f9725f141077a34affb42088946 2006.0/RPMS/kernel-xen0-2.6.12.25mdk-1-1mdk.i586.rpm d280fd356d01831e6dbe5f0fc73c741b 2006.0/RPMS/kernel-xenU-2.6.12.25mdk-1-1mdk.i586.rpm c0a388efafe83a187a58d582ddf9cafb 2006.0/SRPMS/kernel-2.6.12.25mdk-1-1mdk.src.rpm Mandriva Linux 2006.0/X86_64: 54c6b69a3ce44d4dfb217f4b4f620293 x86_64/2006.0/RPMS/kernel-2.6.12.25mdk-1-1mdk.x86_64.rpm 0eded734bf839d253c18d4849507a687 x86_64/2006.0/RPMS/kernel-BOOT-2.6.12.25mdk-1-1mdk.x86_64.rpm c379d55bcaee5070b46475b2e1cbce0a x86_64/2006.0/RPMS/kernel-smp-2.6.12.25mdk-1-1mdk.x86_64.rpm 2fad12f6ea68fdd1d000c2602f47a0a3 x86_64/2006.0/RPMS/kernel-source-2.6.12.25mdk-1-1mdk.x86_64.rpm 1ae8c5f75d5660e511cfe2db62a02056 x86_64/2006.0/RPMS/kernel-source-stripped-2.6.12.25mdk-1-1mdk.x86_64.rpm 160c2425b4be695feaafffdb59cc8fcd x86_64/2006.0/RPMS/kernel-xen0-2.6.12.25mdk-1-1mdk.x86_64.rpm 677a458c0eb70f9f8a5bd9553b96f589 x86_64/2006.0/RPMS/kernel-xenU-2.6.12.25mdk-1-1mdk.x86_64.rpm c0a388efafe83a187a58d582ddf9cafb x86_64/2006.0/SRPMS/kernel-2.6.12.25mdk-1-1mdk.src.rpm _______________________________________________________________________ To upgrade automatically use MandrivaUpdate or urpmi.
