The NTFS filesystem code in Linux kernel 2.6.x up to 2.6.18, and possibly other versions, allows local users to cause a denial of service (CPU consumption) via a malformed NTFS file stream that triggers an infinite loop in the __find_get_block_slow function.

This kernel update fixes the following security problems :

  - A bug within the UDF filesystem that caused machine     hangs when truncating files on the filesystem was fixed.
    [#186226]. (CVE-2006-4145)

  - A potential crash when receiving IPX packets was fixed.
    This problem is thought not to be exploitable. [#197809]

  - A problem in DVB packet handling could be used to crash     the machine when receiving DVB net packages is active.
    [#201429]. (CVE-2006-4623)

  - A struct file leak was fixed in the perfmon(2) system     call on the Itanium architecture. [#202269].
    (CVE-2006-3741)

  - A malformed ELF image can be used on the Itanium     architecture to trigger a kernel crash (denial of     service) when a local attacker can supply it to be     started. [#203822]. (CVE-2006-4538)

  - A problem in the ATM protocol handling clip_mkip     function could be used by remote attackers to     potentially crash the machine. [#205383].
    (CVE-2006-4997)

CVE-2006-5757/

  - A problem in the grow_buffers function could be used to     crash or hang the machine using a corrupted filesystem.
    This affects filesystem types ISO9660 and NTFS.
    [#205384]. (CVE-2006-6060)

  - On the i386 architecture the ELFAGS content was not     correctly saved, which could be used by local attackers     to crash other programs using the AC and NT flag or to     escalate privileges by waiting for iopl privileges to be     leaked. [#209386]. (CVE-2006-5173)

  - On the S/390 architecture copy_from_user() could be used     by local attackers to read kernel memory. [#209880].
    (CVE-2006-5174)

  - A problem in IPv6 flowlabel handling can be used by     local attackers to hang the machine. [#216590].
    (CVE-2006-5619)

  - On the PowerPC architecture a syscall has been wired     without the proper futex implementation that can be     exploited by a local attacker to hang the machine.
    [#217295]. (CVE-2006-5648)

  - On the PowerPC architecture the proper futex     implementation was missing a fix for alignment check     which could be used by a local attacker to crash the     machine. [#217295]. (CVE-2006-5649)

  - A problem in cramfs could be used to crash the machine     during mounting a crafted cramfs image. This requires an     attacker to supply such a crafted image and have a user     mount it. [#218237]. (CVE-2006-5823)

  - A problem in the ext3 filesystem could be used by     attackers able to supply a crafted ext3 image to cause a     denial of service or further data corruption if a user     mounts this image. [#220288]. (CVE-2006-6053)

  - Missing return code checking in the HFS could be used to     crash machine when a user complicit attacker is able to     supply a specially crafted HFS image. [#221230].
    (CVE-2006-6056)

  - Multiple unspecified vulnerabilities in netfilter for     IPv6 code allow remote attackers to bypass intended     restrictions via fragmentation attack vectors, aka (1)     'ip6_tables protocol bypass bug' and (2) 'ip6_tables     extension header bypass bug'. [#221313]. (CVE-2006-4572)

  - An integer overflow in the networking bridge ioctl     starting with Kernel 2.6.7 could be used by local     attackers to overflow kernel memory buffers and     potentially escalate privileges [#222656].
    (CVE-2006-5751)

Several local and remote vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service or the execution of arbitrary code. 

This update also fixes a regression in the smbfs subsystem which was introduced in DSA-1233which caused symlinks to be interpreted as regular files.

The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2005-4811     David Gibson reported an issue in the hugepage code     which could permit a local DoS (system crash) on     appropriately configured systems.

  - CVE-2006-4814     Doug Chapman discovered a potential local DoS (deadlock)     in the mincore function caused by improper lock     handling.

  - CVE-2006-4623     Ang Way Chuang reported a remote DoS (crash) in the dvb     driver which can be triggered by a ULE package with an     SNDU length of 0.

  - CVE-2006-5753     Eric Sandeen provided a fix for a local memory     corruption vulnerability resulting from a     misinterpretation of return values when operating on     inodes which have been marked bad.

  - CVE-2006-5754     Darrick Wong discovered a local DoS (crash)     vulnerability resulting from the incorrect     initialization of 'nr_pages' in aio_setup_ring().

  - CVE-2006-5757     LMH reported a potential local DoS which could be     exploited by a malicious user with the privileges to     mount and read a corrupted iso9660 filesystem.

  - CVE-2006-6053     LMH reported a potential local DoS which could be     exploited by a malicious user with the privileges to     mount and read a corrupted ext3 filesystem.

  - CVE-2006-6056     LMH reported a potential local DoS which could be     exploited by a malicious user with the privileges to     mount and read a corrupted hfs filesystem on systems     with SELinux hooks enabled (Debian does not enable     SELinux by default).

  - CVE-2006-6060     LMH reported a potential local DoS (infinite loop) which     could be exploited by a malicious user with the     privileges to mount and read a corrupted NTFS     filesystem.

  - CVE-2006-6106     Marcel Holtman discovered multiple buffer overflows in     the Bluetooth subsystem which can be used to trigger a     remote DoS (crash) and potentially execute arbitrary     code.

  - CVE-2006-6535     Kostantin Khorenko discovered an invalid error path in     dev_queue_xmit() which could be exploited by a local     user to cause data corruption.

  - CVE-2007-0958     Santosh Eraniose reported a vulnerability that allows     local users to read otherwise unreadable files by     triggering a core dump while using PT_INTERP. This is     related to CVE-2004-1073.

  - CVE-2007-1357     Jean Delvare reported a vulnerability in the appletalk     subsystem. Systems with the appletalk module loaded can     be triggered to crash by other systems on the local     network via a malformed frame.

  - CVE-2007-1592     Masayuki Nakagawa discovered that flow labels were     inadvertently being shared between listening sockets and     child sockets. This defect can be exploited by local     users to cause a DoS (Oops).
