 Mandriva Linux Security Advisory                         MDVSA-2008:112

 Package : kernel
 Date    : June 12, 2008
 Affected: 2007.1
 _______________________________________________________________________
 
 Problem Description:
 
 Some vulnerabilities were discovered and corrected in the Linux
 2.6 kernel:
 
 The Datagram Congestion Control Protocol (DCCP) subsystem in the
 Linux kernel 2.6.18, and probably other versions, does not properly
 check feature lengths, which might allow remote attackers to execute
 arbitrary code, related to an unspecified overflow. (CVE-2008-2358)
 
 VFS in the Linux kernel before 2.6.22.16, and 2.6.23.x before
 2.6.23.14, performs tests of access mode by using the flag variable
 instead of the acc_mode variable, which might allow local users to
 bypass intended permissions and remove directories. (CVE-2008-0001)
 
 Linux kernel before 2.6.22.17, when using certain drivers that register
 a fault handler that does not perform range checks, allows local users
 to access kernel memory via an out-of-range offset. (CVE-2008-0007)
 
 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-2007-5966)
 
 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 related to tmpfs, which might allow local
 users to read sensitive kernel data or cause a denial of service
 (crash). (CVE-2007-6417)
 
 The isdn_ioctl function in isdn_common.c in Linux kernel 2.6.23
 allows local users to cause a denial of service via a crafted ioctl
 struct in which iocts is not null terminated, which triggers a buffer
 overflow. (CVE-2007-6151)
 
 The do_coredump function in fs/exec.c in Linux kernel 2.4.x and 2.6.x
 up to 2.6.24-rc3, and possibly other versions, does not change the
 UID of a core dump file if it exists before a root process creates
 a core dump in the same location, which might allow local users to
 obtain sensitive information. (CVE-2007-6206)
 
 Buffer overflow in the isdn_net_setcfg function in isdn_net.c in
 Linux kernel 2.6.23 allows local users to have an unknown impact via
 a crafted argument to the isdn_ioctl function. (CVE-2007-6063)
 
 The wait_task_stopped function in the Linux kernel before 2.6.23.8
 checks a TASK_TRACED bit instead of an exit_state value, which
 allows local users to cause a denial of service (machine crash) via
 unspecified vectors. NOTE: some of these details are obtained from
 third party information. (CVE-2007-5500)
 
 The minix filesystem code in Linux kernel 2.6.x before 2.6.24,
 including 2.6.18, allows local users to cause a denial of service
 (hang) via a malformed minix file stream that triggers an infinite
 loop in the minix_bmap function. NOTE: this issue might be due to an
 integer overflow or signedness error. (CVE-2006-6058)
