All Red Hat Enterprise Linux 4 users are advised to upgrade their kernels to the packages associated with their machine architecture and configurations as listed in this erratum.

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. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2006-5823     LMH reported a potential local DoS which could be     exploited by a malicious user with the privileges to     mount and read a corrupted cramfs filesystem.

  - CVE-2006-6054     LMH reported a potential local DoS which could be     exploited by a malicious user with the privileges to     mount and read a corrupted ext2 filesystem.

  - CVE-2006-6058     LMH reported an issue in the minix filesystem that     allows local users with mount privileges to create a DoS     (printk flood) by mounting a specially crafted corrupt     filesystem.

  - CVE-2006-7203     OpenVZ Linux kernel team reported an issue in the smbfs     filesystem which can be exploited by local users to     cause a DoS (oops) during mount.

  - CVE-2007-1353     Ilja van Sprundel discovered that kernel memory could be     leaked via the Bluetooth setsockopt call due to an     uninitialized stack buffer. This could be used by local     attackers to read the contents of sensitive kernel     memory.

  - CVE-2007-2172     Thomas Graf reported a typo in the DECnet protocol     handler that could be used by a local attacker to     overrun an array via crafted packets, potentially     resulting in a Denial of Service (system crash). A     similar issue exists in the IPV4 protocol handler and     will be fixed in a subsequent update.

  - CVE-2007-2525     Florian Zumbiehl discovered a memory leak in the PPPOE     subsystem caused by releasing a socket before     PPPIOCGCHAN is called upon it. This could be used by a     local user to DoS a system by consuming all available     memory.

  - CVE-2007-3105     The PaX Team discovered a potential buffer overflow in     the random number generator which may permit local users     to cause a denial of service or gain additional     privileges. This issue is not believed to effect default     Debian installations where only root has sufficient     privileges to exploit it.

  - CVE-2007-3739     Adam Litke reported a potential local denial of service     (oops) on powerpc platforms resulting from unchecked VMA     expansion into address space reserved for hugetlb pages.

  - CVE-2007-3740     Steve French reported that CIFS filesystems with     CAP_UNIX enabled were not honoring a process' umask     which may lead to unintentionally relaxed permissions.

  - CVE-2007-3848     Wojciech Purczynski discovered that pdeath_signal was     not being reset properly under certain conditions which     may allow local users to gain privileges by sending     arbitrary signals to suid binaries.

  - CVE-2007-4133     Hugh Dickins discovered a potential local DoS (panic) in     hugetlbfs. A misconversion of hugetlb_vmtruncate_list to     prio_tree may allow local users to trigger a BUG_ON()     call in exit_mmap.

  - CVE-2007-4308     Alan Cox reported an issue in the aacraid driver that     allows unprivileged local users to make ioctl calls     which should be restricted to admin privileges.

  - CVE-2007-4573     Wojciech Purczynski discovered a vulnerability that can     be exploited by a local user to obtain superuser     privileges on x86_64 systems. This resulted from     improper clearing of the high bits of registers during     ia32 system call emulation. This vulnerability is     relevant to the Debian amd64 port as well as users of     the i386 port who run the amd64 linux-image flavour.

  - CVE-2007-5093     Alex Smith discovered an issue with the pwc driver for     certain webcam devices. If the device is removed while a     userspace application has it open, the driver will wait     for userspace to close the device, resulting in a     blocked USB subsystem. This issue is of low security     impact as it requires the attacker to either have     physical access to the system or to convince a user with     local access to remove the device on their behalf.

  - CVE-2007-6063     Venustech AD-LAB discovered a a buffer overflow in the     isdn ioctl handling, exploitable by a local user.

  - CVE-2007-6151     ADLAB discovered a possible memory overrun in the ISDN     subsystem that may permit a local user to overwrite     kernel memory by issuing ioctls with unterminated data.

  - CVE-2007-6206     Blake Frantz discovered that when a core file owned by a     non-root user exists, and a root-owned process dumps     core over it, the core file retains its original     ownership. This could be used by a local user to gain     access to sensitive information.

  - CVE-2007-6694     Cyrill Gorcunov reported a NULL pointer dereference in     code specific to the CHRP PowerPC platforms. Local users     could exploit this issue to achieve a Denial of Service     (DoS).

  - CVE-2008-0007     Nick Piggin of SuSE discovered a number of issues in     subsystems which register a fault handler for memory     mapped areas. This issue can be exploited by local users     to achieve a Denial of Service (DoS) and possibly     execute arbitrary code.

The following matrix lists additional packages that were rebuilt for compatibility with or to take advantage of this update :

                             Debian 3.1 (sarge)            kernel-image-2.6.8-alpha    2.6.8-17sarge1                kernel-image-2.6.8-amd64    2.6.8-17sarge1                kernel-image-2.6.8-hppa     2.6.8-7sarge1                 kernel-image-2.6.8-i386     2.6.8-17sarge1                kernel-image-2.6.8-ia64     2.6.8-15sarge1                kernel-image-2.6.8-m68k     2.6.8-5sarge1                 kernel-image-2.6.8-s390     2.6.8-6sarge1                 kernel-image-2.6.8-sparc    2.6.8-16sarge1                kernel-patch-powerpc-2.6.8  2.6.8-13sarge1                fai-kernels                 1.9.1sarge8

Mark Dowd discovered that the netfilter iptables module did not correcly handle fragmented IPv6 packets. By sending specially crafted packets, a remote attacker could exploit this to bypass firewall rules. This has has already been fixed for Ubuntu 6.10 in USN-395-1;
this is the corresponding fix for Ubuntu 6.06.(CVE-2006-4572)

Doug Chapman discovered an improper lock handling in the mincore() function. A local attacker could exploit this to cause an eternal hang in the kernel, rendering the machine unusable. (CVE-2006-4814)

Al Viro reported that the ISDN PPP module did not initialize the reset state timer. By sending specially crafted ISDN packets, a remote attacker could exploit this to crash the kernel. (CVE-2006-5749)

Various syscalls (like listxattr()) misinterpreted the return value of return_EIO() when encountering bad inodes. By issuing particular system calls on a malformed file system, a local attacker could exploit this to crash the kernel. (CVE-2006-5753)

The task switching code did not save and restore EFLAGS of processes.
By starting a specially crafted executable, a local attacker could exploit this to eventually crash many other running processes. This only affects the amd64 platform. (CVE-2006-5755)

A race condition was found in the grow_buffers() function. By mounting a specially crafted ISO9660 or NTFS file system, a local attacker could exploit this to trigger an infinite loop in the kernel, rendering the machine unusable. (CVE-2006-5757)

A buffer overread was found in the zlib_inflate() function. By tricking an user into mounting a specially crafted file system which uses zlib compression (such as cramfs), this could be exploited to crash the kernel. (CVE-2006-5823)

The ext3 file system driver did not properly handle corrupted data structures. By mounting a specially crafted ext3 file system, a local attacker could exploit this to crash the kernel. (CVE-2006-6053)

The ext2 file system driver did not properly handle corrupted data structures. By mounting a specially crafted ext2 file system, a local attacker could exploit this to crash the kernel. (CVE-2006-6054)

The hfs file system driver did not properly handle corrupted data structures. By mounting a specially crafted hfs file system, a local attacker could exploit this to crash the kernel. This only affects systems which enable SELinux (Ubuntu disables SELinux by default).
(CVE-2006-6056)

Several vulnerabilities have been found in the GFS2 file system driver. Since this driver has never actually worked in Ubuntu 6.10, it has been disabled. This only affects Ubuntu 6.10. (CVE-2006-6057)

Marcel Holtman discovered several buffer overflows in the Bluetooth driver. By sending Bluetooth packets with specially crafted CAPI messages, a remote attacker could exploit these to crash the kernel.
(CVE-2006-6106).
