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-2004-2731     infamous41md reported multiple integer overflows in the     Sbus PROM driver that would allow for a DoS (Denial of     Service) attack by a local user, and possibly the     execution of arbitrary code.

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

  - 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-2006-5823     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-2006-6053     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-2006-6054     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-2006-6106     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-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-2007-1592     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).

  - 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-2007-3848     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-2007-4308     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-2007-4311     PaX team discovered an issue in the random driver where     a defect in the reseeding code leads to a reduction in     entropy.

  - 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)             alsa-modules-i386            1.0.8+2sarge2                  kernel-image-2.4.27-arm      2.4.27-2sarge6                 kernel-image-2.4.27-m68k     2.4.27-3sarge6                 kernel-image-speakup-i386    2.4.27-1.1sarge5               kernel-image-2.4.27-alpha    2.4.27-10sarge6                kernel-image-2.4.27-s390     2.4.27-2sarge6                 kernel-image-2.4.27-sparc    2.4.27-9sarge6                 kernel-image-2.4.27-i386     2.4.27-10sarge6                kernel-image-2.4.27-ia64     2.4.27-10sarge6                kernel-patch-2.4.27-mips     2.4.27-10.sarge4.040815-3      kernel-patch-powerpc-2.4.27  2.4.27-10sarge6                kernel-latest-2.4-alpha      101sarge3                      kernel-latest-2.4-i386       101sarge2                      kernel-latest-2.4-s390       2.4.27-1sarge2                 kernel-latest-2.4-sparc      42sarge3                       i2c                          1:2.9.1-1sarge2                lm-sensors                   1:2.9.1-1sarge4                mindi-kernel                 2.4.27-2sarge5                 pcmcia-modules-2.4.27-i386   3.2.5+2sarge2                  hostap-modules-i386          1:0.3.7-1sarge3                systemimager                 3.2.3-6sarge5

This kernel update fixes the following security problems :

CVE-2008-0007: Insufficient range checks in certain fault handlers could be used by local attackers to potentially read or write kernel memory.

CVE-2008-0001: Incorrect access mode checks could be used by local attackers to corrupt directory contents and so cause denial of service attacks or potentially execute code.

CVE-2007-5966: Integer overflow in the hrtimer_start function in kernel/hrtimer.c in the Linux kernel before 2.6.23.10 allows local users to execute arbitrary code or cause a denial of service (panic) via a large relative timeout value. NOTE: some of these details are obtained from third-party information.

CVE-2007-3843: The Linux kernel checked the wrong global variable for the CIFS sec mount option, which might allow remote attackers to spoof CIFS network traffic that the client configured for security signatures, as demonstrated by lack of signing despite sec=ntlmv2i in a SetupAndX request.

CVE-2007-2242: The IPv6 protocol allows remote attackers to cause a denial of service via crafted IPv6 type 0 route headers (IPV6_RTHDR_TYPE_0) that create network amplification between two routers.

CVE-2007-6417: The shmem_getpage function (mm/shmem.c) in Linux kernel 2.6.11 through 2.6.23 does not properly clear allocated memory in some rare circumstances, which might allow local users to read sensitive kernel data or cause a denial of service (crash).

CVE-2007-4308: The (1) aac_cfg_open and (2) aac_compat_ioctl functions in the SCSI layer ioctl path in aacraid in the Linux kernel did not check permissions for ioctls, which might have allowed local users to cause a denial of service or gain privileges.

CVE-2007-3740: The CIFS filesystem, when Unix extension support is enabled, does not honor the umask of a process, which allows local users to gain privileges.

CVE-2007-3848: The Linux kernel allowed local users to send arbitrary signals to a child process that is running at higher privileges by causing a setuid-root parent process to die, which delivers an attacker-controlled parent process death signal (PR_SET_PDEATHSIG).

CVE-2007-4997: Integer underflow in the ieee80211_rx function in net/ieee80211/ieee80211_rx.c in the Linux kernel allowed remote attackers to cause a denial of service (crash) via a crafted SKB length value in a runt IEEE 802.11 frame when the IEEE80211_STYPE_QOS_DATA flag is set, aka an 'off-by-two error.'

CVE-2007-6063: Buffer overflow in the isdn_net_setcfg function in isdn_net.c in the Linux kernel allowed local users to have an unknown impact via a crafted argument to the isdn_ioctl function.

CVE-none-yet: A failed change_hat call can result in an apparmored task becoming unconfined (326546).
