概要

The remote SuSE 9 host is missing a security-related patch.

説明

This patch updates the SUSE Linux Enterprise Server 9 kernel to fix various security issues and some bugs.

The following security issues were fixed :

- The hci_uart_tty_open function in the HCI UART driver (drivers/bluetooth/hci_ldisc.c) in the Linux kernel did not verify whether the tty has a write operation, which allowed local users to cause a denial of service (NULL pointer dereference) via vectors related to the Bluetooth driver. (CVE-2010-4242)

- The load_mixer_volumes function in sound/oss/soundcard.c in the OSS sound subsystem in the Linux kernel incorrectly expected that a certain name field ends with a '\0' character, which allowed local users to conduct buffer overflow attacks and gain privileges, or possibly obtain sensitive information from kernel memory, via a SOUND_MIXER_SETLEVELS ioctl call. (CVE-2010-4527)

- Integer underflow in the irda_getsockopt function in net/irda/af_irda.c in the Linux kernel on platforms other than x86 allowed local users to obtain potentially sensitive information from kernel heap memory via an IRLMP_ENUMDEVICES getsockopt call. (CVE-2010-4529)

- The aun_incoming function in net/econet/af_econet.c in the Linux kernel, when Econet is enabled, allowed remote attackers to cause a denial of service (NULL pointer dereference and OOPS) by sending an Acorn Universal Networking (AUN) packet over UDP. (CVE-2010-4342)

- fs/jfs/xattr.c in the Linux kernel did not properly handle a certain legacy format for storage of extended attributes, which might have allowed local users by bypass intended xattr namespace restrictions via an 'os2.' substring at the beginning of a name.
(CVE-2010-2946)

- Stack-based buffer overflow in the econet_sendmsg function in net/econet/af_econet.c in the Linux kernel, when an econet address is configured, allowed local users to gain privileges by providing a large number of iovec structures. (CVE-2010-3848)

- The econet_sendmsg function in net/econet/af_econet.c in the Linux kernel, when an econet address is configured, allowed local users to cause a denial of service (NULL pointer dereference and OOPS) via a sendmsg call that specifies a NULL value for the remote address field.
(CVE-2010-3849)

- The ec_dev_ioctl function in net/econet/af_econet.c in the Linux kernel does not require the CAP_NET_ADMIN capability, which allowed local users to bypass intended access restrictions and configure econet addresses via an SIOCSIFADDR ioctl call. (CVE-2010-3850)

- The do_exit function in kernel/exit.c in the Linux kernel did not properly handle a KERNEL_DS get_fs value, which allowed local users to bypass intended access_ok restrictions, overwrite arbitrary kernel memory locations, and gain privileges by leveraging a (1) BUG, (2) NULL pointer dereference, or (3) page fault, as demonstrated by vectors involving the clear_child_tid feature and the splice system call. (CVE-2010-4258)

- Multiple integer overflows in the (1) pppol2tp_sendmsg function in net/l2tp/l2tp_ppp.c, and the (2) l2tp_ip_sendmsg function in net/l2tp/l2tp_ip.c, in the PPPoL2TP and IPoL2TP implementations in the Linux kernel allowed local users to cause a denial of service (heap memory corruption and panic) or possibly gain privileges via a crafted sendto call. (CVE-2010-4160)

- Integer overflow in the ioc_general function in drivers/scsi/gdth.c in the Linux kernel on 64-bit platforms allowed local users to cause a denial of service (memory corruption) or possibly have unspecified other impact via a large argument in an ioctl call.
(CVE-2010-4157)

- Multiple integer underflows in the x25_parse_facilities function in net/x25/x25_facilities.c in the Linux kernel allowed remote attackers to cause a denial of service (system crash) via malformed X.25 (1) X25_FAC_CLASS_A, (2) X25_FAC_CLASS_B, (3) X25_FAC_CLASS_C, or (4) X25_FAC_CLASS_D facility data, a different vulnerability than CVE-2010-3873. (CVE-2010-4164)

- The sk_run_filter function in net/core/filter.c in the Linux kernel did not check whether a certain memory location has been initialized before executing a (1) BPF_S_LD_MEM or (2) BPF_S_LDX_MEM instruction, which allowed local users to obtain potentially sensitive information from kernel stack memory via a crafted socket filter. (CVE-2010-4158)

- Multiple integer overflows in the snd_ctl_new function in sound/core/control.c in the Linux kernel allowed local users to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a crafted (1) SNDRV_CTL_IOCTL_ELEM_ADD or (2) SNDRV_CTL_IOCTL_ELEM_REPLACE ioctl call. (CVE-2010-3442)

- The snd_hdspm_hwdep_ioctl function in sound/pci/rme9652/hdspm.c in the Linux kernel did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory via an SNDRV_HDSPM_IOCTL_GET_CONFIG_INFO ioctl call.
(CVE-2010-4081)

- The ipc subsystem in the Linux kernel did not initialize certain structures, which allowed local users to obtain potentially sensitive information from kernel stack memory via vectors related to the (1) compat_sys_semctl, (2) compat_sys_msgctl, and (3) compat_sys_shmctl functions in ipc/compat.c; and the (4) compat_sys_mq_open and (5) compat_sys_mq_getsetattr functions in ipc/compat_mq.c. (CVE-2010-4073)

- The copy_shmid_to_user function in ipc/shm.c in the Linux kernel did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory via vectors related to the shmctl system call and the 'old shm interface.'. (CVE-2010-4072)

- The copy_semid_to_user function in ipc/sem.c in the Linux kernel did not initialize a certain structure, which allowed local users to obtain potentially sensitive information from kernel stack memory via a (1) IPC_INFO, (2) SEM_INFO, (3) IPC_STAT, or (4) SEM_STAT command in a semctl system call. (CVE-2010-4083)

- Integer overflow in the do_io_submit function in fs/aio.c in the Linux kernel allowed local users to cause a denial of service or possibly have unspecified other impact via crafted use of the io_submit system call. (CVE-2010-3067)

- Multiple integer signedness errors in net/rose/af_rose.c in the Linux kernel allowed local users to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a rose_getname function call, related to the rose_bind and rose_connect functions. (CVE-2010-3310)
