    description 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). and the following non security bugs : - patches.suse/apparmor-r206-310260.diff: AppArmor - add audit capability names (310260). - patches.suse/apparmor-r326-240982.diff: AppArmor - fix memory corruption if policy load fails (240982). - patches.suse/apparmor-r400-221567.diff: AppArmor - kernel dead locks when audit back log occurs (221567). - patches.suse/apparmor-r405-247679.diff: AppArmor - apparmor fails to log link reject in complain mode (247679). - patches.suse/apparmor-r473-326556.diff: AppArmor - fix race on ambiguous deleted file name (326556). - patches.suse/apparmor-r479-257748.diff: AppArmor - fix kernel crash that can occur on profile removal (257748). - patches.fixes/usb_unusual_292931.diff: add quirk needed for 1652:6600 (292931). - patches.drivers/r8169-perform-a-PHY-reset-before.patch: r8169: perform a PHY reset before any other operation at boot time (345658). - patches.drivers/r8169-more-alignment-for-the-0x8168: refresh. - patches.fixes/usb_336850.diff: fix missing quirk leading to a device disconnecting under load (336850). - patches.fixes/avm-fix-capilib-locking: [ISDN] Fix random hard freeze with AVM cards.

    description The compat_sys_mount function allowed local users to cause a denial of service when mounting a smbfs filesystem in compatibility mode. (CVE-2006-7203) The Omnikey CardMan 4040 driver (cm4040_cs) did not limit the size of buffers passed to read() and write(). A local attacker could exploit this to execute arbitrary code with kernel privileges. (CVE-2007-0005) Due to a variable handling flaw in the ipv6_getsockopt_sticky() function a local attacker could exploit the getsockopt() calls to read arbitrary kernel memory. This could disclose sensitive data. (CVE-2007-1000) Ilja van Sprundel discovered that Bluetooth setsockopt calls could leak kernel memory contents via an uninitialized stack buffer. A local attacker could exploit this flaw to view sensitive kernel information. (CVE-2007-1353) A flaw was discovered in the handling of netlink messages. Local attackers could cause infinite recursion leading to a denial of service. (CVE-2007-1861) A flaw was discovered in the IPv6 stack's handling of type 0 route headers. By sending a specially crafted IPv6 packet, a remote attacker could cause a denial of service between two IPv6 hosts. (CVE-2007-2242) The random number generator was hashing a subset of the available entropy, leading to slightly less random numbers. Additionally, systems without an entropy source would be seeded with the same inputs at boot time, leading to a repeatable series of random numbers. (CVE-2007-2453) A flaw was discovered in the PPP over Ethernet implementation. Local attackers could manipulate ioctls and cause kernel memory consumption leading to a denial of service. (CVE-2007-2525) An integer underflow was discovered in the cpuset filesystem. If mounted, local attackers could obtain kernel memory using large file offsets while reading the tasks file. This could disclose sensitive data. (CVE-2007-2875) Vilmos Nebehaj discovered that the SCTP netfilter code did not correctly validate certain states. A remote attacker could send a specially crafted packet causing a denial of service. (CVE-2007-2876) Luca Tettamanti discovered a flaw in the VFAT compat ioctls on 64-bit systems. A local attacker could corrupt a kernel_dirent struct and cause a denial of service. (CVE-2007-2878). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

  • NASL family SuSE Local Security Checks
    NASL id SUSE_KERNEL-4186.NASL
    description This kernel update fixes the following security problems : - 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-2007-2242) The default is that RH0 is disabled now. To adjust this, write to the file /proc/net/accept_source_route6. - The random number feature in the Linux kernel 2.6 (1) did not properly seed pools when there is no entropy, or (2) used an incorrect cast when extracting entropy, which might have caused the random number generator to provide the same values after reboots on systems without an entropy source. (CVE-2007-2453) - A NULL pointer dereference in SCTP connection tracking could be caused by a remote attacker by sending specially crafted packets. Note that this requires SCTP set-up and active to be exploitable. (CVE-2007-2876) - Stack-based buffer overflow in the random number generator (RNG) implementation in the Linux kernel before 2.6.22 might allow local root users to cause a denial of service or gain privileges by setting the default wakeup threshold to a value greater than the output pool size, which triggers writing random numbers to the stack by the pool transfer function involving 'bound check ordering'. (CVE-2007-3105) Since this value can only be changed by a root user, exploitability is low. - The signal handling in the Linux kernel, when run on PowerPC systems using HTX, allows local users to cause a denial of service via unspecified vectors involving floating point corruption and concurrency. (CVE-2007-3107) - Memory leak in the PPP over Ethernet (PPPoE) socket implementation in the Linux kernel allowed local users to cause a denial of service (memory consumption) by creating a socket using connect, and releasing it before the PPPIOCGCHAN ioctl is initialized. (CVE-2007-2525) - The lcd_write function in drivers/usb/misc/usblcd.c in the Linux kernel did not limit the amount of memory used by a caller, which allowed local users to cause a denial of service (memory consumption). (CVE-2007-3513) - A local attacker could send a death signal to a setuid root program under certain conditions, potentially causing unwanted behaviour in this program. (CVE-2007-3848) - On machines with a Intel i965 based graphics card local users with access to the direct rendering devicenode could overwrite memory on the machine and so gain root privileges. (CVE-2007-3851) - Fixed a denial of service possibility where a local attacker with access to a pwc camera device could hang the USB subsystem.

    description Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel : The Linux kernel did not properly save or restore EFLAGS during a context switch, or reset the flags when creating new threads, which allowed local users to cause a denial of service (process crash) (CVE-2006-5755). The compat_sys_mount function in fs/compat.c allowed local users to cause a denial of service (NULL pointer dereference and oops) by mounting a smbfs file system in compatibility mode (CVE-2006-7203). The nfnetlink_log function in netfilter allowed an attacker to cause a denial of service (crash) via unspecified vectors which would trigger a NULL pointer dereference (CVE-2007-1496). The nf_conntrack function in netfilter did not set nfctinfo during reassembly of fragmented packets, which left the default value as IP_CT_ESTABLISHED and could allow remote attackers to bypass certain rulesets using IPv6 fragments (CVE-2007-1497). The netlink functionality did not properly handle NETLINK_FIB_LOOKUP replies, which allowed a remote attacker to cause a denial of service (resource consumption) via unspecified vectors, probably related to infinite recursion (CVE-2007-1861). A typo in the Linux kernel caused RTA_MAX to be used as an array size instead of RTN_MAX, which lead to an out of bounds access by certain functions (CVE-2007-2172). The IPv6 protocol allowed remote attackers to cause a denial of service via crafted IPv6 type 0 route headers that create network amplification between two routers (CVE-2007-2242). The random number feature did not properly seed pools when there was no entropy, or used an incorrect cast when extracting entropy, which could cause the random number generator to provide the same values after reboots on systems without an entropy source (CVE-2007-2453). A memory leak in the PPPoE socket implementation allowed local users to cause a denial of service (memory consumption) by creating a socket using connect, and releasing it before the PPPIOCGCHAN ioctl is initialized (CVE-2007-2525). An integer underflow in the cpuset_tasks_read function, when the cpuset filesystem is mounted, allowed local users to obtain kernel memory contents by using a large offset when reading the /dev/cpuset/tasks file (CVE-2007-2875). The sctp_new function in netfilter allowed remote attackers to cause a denial of service by causing certain invalid states that triggered a NULL pointer dereference (CVE-2007-2876). In addition to these security fixes, other fixes have been included such as : - Fix crash on netfilter when nfnetlink_log is used on certain hooks on packets forwarded to or from a bridge - Fixed busy sleep on IPVS which caused high load averages - Fixed possible race condition on ext[34]_link - Fixed missing braces in condition block that led to wrong behaviour in NFS - Fixed XFS lock deallocation that resulted in oops when unmounting To update your kernel, please follow the directions located at : http://www.mandriva.com/en/security/kernelupdate

    description A buffer overflow was discovered in the Moxa serial driver. Local attackers could execute arbitrary code and gain root privileges. (CVE-2005-0504) A flaw was discovered in the IPv6 stack's handling of type 0 route headers. By sending a specially crafted IPv6 packet, a remote attacker could cause a denial of service between two IPv6 hosts. (CVE-2007-2242) A flaw in the sysfs_readdir function allowed a local user to cause a denial of service by dereferencing a NULL pointer. (CVE-2007-3104) A buffer overflow was discovered in the random number generator. In environments with granular assignment of root privileges, a local attacker could gain additional privileges. (CVE-2007-3105) It was discovered that certain setuid-root processes did not correctly reset process death signal handlers. A local user could manipulate this to send signals to processes they would not normally have access to. (CVE-2007-3848) It was discovered that the aacraid SCSI driver did not correctly check permissions on certain ioctls. A local attacker could cause a denial of service or gain privileges. (CVE-2007-4308). Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

  • NASL family SuSE Local Security Checks
    NASL id SUSE_KERNEL-4185.NASL
    description This kernel update fixes the following security problems : - 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-2007-2242) The default is that RH0 is disabled now. To adjust this, write to the file /proc/net/accept_source_route6. - The random number feature in the Linux kernel 2.6 (1) did not properly seed pools when there is no entropy, or (2) used an incorrect cast when extracting entropy, which might have caused the random number generator to provide the same values after reboots on systems without an entropy source. (CVE-2007-2453) - A NULL pointer dereference in SCTP connection tracking could be caused by a remote attacker by sending specially crafted packets. Note that this requires SCTP set-up and active to be exploitable. (CVE-2007-2876) - Stack-based buffer overflow in the random number generator (RNG) implementation in the Linux kernel before 2.6.22 might allow local root users to cause a denial of service or gain privileges by setting the default wakeup threshold to a value greater than the output pool size, which triggers writing random numbers to the stack by the pool transfer function involving 'bound check ordering'. (CVE-2007-3105) Since this value can only be changed by a root user, exploitability is low. - The signal handling in the Linux kernel, when run on PowerPC systems using HTX, allows local users to cause a denial of service via unspecified vectors involving floating point corruption and concurrency. (CVE-2007-3107) - Memory leak in the PPP over Ethernet (PPPoE) socket implementation in the Linux kernel allowed local users to cause a denial of service (memory consumption) by creating a socket using connect, and releasing it before the PPPIOCGCHAN ioctl is initialized. (CVE-2007-2525) - The lcd_write function in drivers/usb/misc/usblcd.c in the Linux kernel did not limit the amount of memory used by a caller, which allowed local users to cause a denial of service (memory consumption). (CVE-2007-3513) - A local attacker could send a death signal to a setuid root program under certain conditions, potentially causing unwanted behaviour in this program. (CVE-2007-3848) - On machines with a Intel i965 based graphics card local users with access to the direct rendering devicenode could overwrite memory on the machine and so gain root privileges. (CVE-2007-3851) - Fixed a denial of service possibility where a local attacker with access to a pwc camera device could hang the USB subsystem.

    title SuSE 10 Security Update : Linux kernel (ZYPP Patch Number 4185)
  • NASL family SuSE Local Security Checks
    NASL id SUSE_KERNEL-3760.NASL
    description This kernel update fixes the following security problems : - CVE-2007-1861: The nl_fib_lookup function in net/ipv4/fib_frontend.c allows attackers to cause a denial of service (kernel panic) via NETLINK_FIB_LOOKUP replies, which trigger infinite recursion and a stack overflow. - CVE-2007-1496: nfnetlink_log in netfilter allows attackers to cause a denial of service (crash) via unspecified vectors involving the (1) nfulnl_recv_config function, (2) using 'multiple packets per netlink message', and (3) bridged packets, which trigger a NULL pointer dereference. - CVE-2007-1497: nf_conntrack in netfilter does not set nfctinfo during reassembly of fragmented packets, which leaves the default value as IP_CT_ESTABLISHED and might allow remote attackers to bypass certain rulesets using IPv6 fragments. Please note that the connection tracking option for IPv6 is not enabled in any currently shipping SUSE Linux kernel, so it does not affect SUSE Linux default kernels. - 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. The behaviour has been disabled by default, and the patch introduces a new sysctl with which the administrator can reenable it again. - CVE-2006-7203: The compat_sys_mount function in fs/compat.c allows local users to cause a denial of service (NULL pointer dereference and oops) by mounting a smbfs file system in compatibility mode ('mount -t smbfs'). - CVE-2007-2453: Seeding of the kernel random generator on boot did not work correctly due to a programming mistake and so the kernel might have more predictable random numbers than assured. - CVE-2007-2876: A NULL pointer dereference in SCTP connection tracking could be caused by a remote attacker by sending specially crafted packets. Note that this requires SCTP set-up and active to be exploitable. and the following non security bugs : - patches.fixes/cpufreq_fix_limited_on_battery.patch: Fix limited freq when booted on battery.
