 Mandriva Linux Security Advisory                         MDKSA-2005:220
 Package : kernel
 Date    : November 30, 2005
 Affected: 10.2
 Problem Description:
 Multiple vulnerabilities in the Linux 2.6 kernel have been discovered
 and corrected in this update:
 The kernel on x86_64 platforms does not use a guard page for the 47-bit
 address page to protect against an AMD K8 bug which allows a local user
 to cause a DoS (CVE-2005-1764).
 The KEYCTL_JOIN_SESSION_KEYRING operation in versions prior to
 contains an error path that does not properly release the session
 management semaphore, which allows local users or remote attackers to
 cause a DoS (semaphore hang) via a new session keyring with an empty
 name string, a long name string, the key quota reached, or ENOMEM
 Kernels prior to do not properly destroy a keyring that is not
 instantiated properly, allowing a local user or remote attacker to
 cause a DoS (oops) via a keyring with a payload that is not empty
 An array index overflow in the xfrm_sk_policy_insert function in
 xfrm_user.c allows local users to cause a DoS (oops or deadlock) and
 possibly execute arbitrary code (CVE-2005-2456).
 The zisofs driver in versions prior to allows local users and
 remove attackers to cause a DoS (crash) via a crafted compressed ISO
 filesystem (CVE-2005-2457).
 inflate.c in the zlib routines in versions prior to allow
 remove attackers to cause a DoS (crash) via a compressed file with
 "improper tables" (CVE-2005-2458).
 The huft_build function in inflate.c in the zlib routines in versions
 prior to returns the wrong value, allowing remote attackers to
 cause a DoS (crash) via a certain compressed file that leads to a null
 pointer dereference (CVE-2005-2459).
 A stack-based buffer overflow in the sendmsg function call in versions
 prior to allow local users to execute arbitrary code by
 calling sendmsg and modifying the message contents in another thread
 The raw_sendmsg function in versions prior to allow local
 users to cause a DoS (change hardware state) or read from arbitrary
 memory via crafted input (CVE-2005-2492).
 A memory leak in the seq_file implementation in the SCSI procfs
 interface (sg.c) in 2.6.13 and earlier allows a local user to cause a
 DoS (memory consumption) via certain repeated reads from
 /proc/scsi/gs/devices file which is not properly handled when the
 next() interator returns NULL or an error (CVE-2005-2800).
 The ipt_recent module in versions prior to 2.6.12 when running on 64bit
 processors allows remote attackers to cause a DoS (kernel panic) via
 certain attacks such as SSH brute force (CVE-2005-2872).
 The ipt_recent module in versions prior to 2.6.12 does not properly
 perform certain tests when the jiffies value is greater than LONG_MAX,
 which can cause ipt_recent netfilter rules to block too early
 Multiple vulnerabilities in versions prior to allow local
 users to cause a DoS (oops from null dereference) via fput in a 32bit
 ioctl on 64-bit x86 systems or sockfd_put in the 32-bit routing_ioctl
 function on 64-bit systems (CVE-2005-3044).
 The sys_set_mempolicy function in mempolicy.c allows local users to
 cause a DoS via a negative first argument (CVE-2005-3053).
 Versions 2.6.8 to 2.6.14-rc2 allow local users to cause a DoS (oops)
 via a userspace process that issues a USB Request Block (URB) to a USB
 device and terminates before the URB is finished, which leads to a
 stale pointer reference (CVE-2005-3055).
 drm.c in version 2.6.13 and earlier creates a debug file in sysfs with
 world-readable and world-writable permissions, allowing local users to
 enable DRM debugging and obtain sensitive information (CVE-2005-3179).
 The Orinoco driver in 2.6.13 and earlier does not properly clear memory
 from a previously used packet whose length is increased, allowing
 remote attackers to obtain sensitive information (CVE-2005-3180).
 Kernels 2.6.13 and earlier, when CONFIG_AUDITSYSCALL is enabled, use an
 incorrect function to free names_cache memory, preventing the memory
 from being tracked by AUDITSYSCALL code and leading to a memory leak
 The VT implementation in version 2.6.12 allows local users to use
 certain IOCTLs on terminals of other users and gain privileges
 Exec does not properly clear posix-timers in multi-threaded
 environments, which result in a resource leak and could allow a large
 number of multiple local users to cause a DoS by using more posix-
 timers than specified by the quota for a single user (CVE-2005-3271).
 The rose_rt_ioctl function rose_route.c in versions prior to 2.6.12
 does not properly verify the ndigis argument for a new route, allowing
 an attacker to trigger array out-of-bounds errors with a large number
 of digipeats (CVE-2005-3273).
 A race condition in ip_vs_conn_flush in versions prior to 2.6.13, when
 running on SMP systems, allows local users to cause a DoS (null
 dereference) by causing a connection timer to expire while the
 connection table is being flushed before the appropriate lock is
 acquired (CVE-2005-3274).
 The NAT code in versions prior to 2.6.13 incorrectly declares a
 variable to be static, allowing remote attackers to cause a DoS (memory
 corruption) by causing two packets for the same protocol to be NATed at
 the same time (CVE-2005-3275).
 The sys_get_thread_area function in process.c in versions prior to and 2.6.13 does not clear a data structure before copying it
 to userspace, which may allow a user process to obtain sensitive
 information (CVE-2005-3276).
 The provided packages are patched to fix these vulnerabilities.  All
 users are encouraged to upgrade to these updated kernels.
