    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 2.6.12.5 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 (CVE-2005-2098). Kernels prior to 2.6.12.5 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 (CVE-2005-2099). 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 2.6.12.5 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 2.6.12.5 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 2.6.12.5 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 2.6.13.1 allow local users to execute arbitrary code by calling sendmsg and modifying the message contents in another thread (CVE-2005-2490). The raw_sendmsg function in versions prior to 2.6.13.1 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 (CVE-2005-2873). Multiple vulnerabilities in versions prior to 2.6.13.2 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 (CVE-2005-3181). The VT implementation in version 2.6.12 allows local users to use certain IOCTLs on terminals of other users and gain privileges (CVE-2005-3257). 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 2.6.12.4 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.

    description Multiple vulnerabilities in the Linux 2.6 kernel have been discovered and corrected in this update : An integer overflow in vc_resize (CVE-2004-1333). A race condition in the sysfs_read_file and sysfs_write_file functions in 2.6.10 and earlier allows local users to read kernel memory and cause a DoS (crash) via large offsets in sysfs files (CVE-2004-2302). An integer signedness error in scsi_ioctl.c (CVE-2005-0180). Netfilter allows a local user to cause a DoS (memory consumption) via certain packet fragments that are reassembled twice, which causes a data structure to be allocated twice (CVE-2005-0210). A DoS in pkt_ioctl in pktcdvc.c (CVE-2005-1589). 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).

A stack-based buffer overflow in the sendmsg function call in versions prior to 2.6.13.1 allow local users to execute arbitrary code by calling sendmsg and modifying the message contents in another thread (CVE-2005-2490). vlan_dev.c in version 2.6.8 allows remote attackers to cause a DoS (oops from null dereference) via certain UDP packets that lead to a function call with the wrong argument (CVE-2005-2548). The kernel does not properly restrict socket policy access to users with the CAP_NET_ADMIN capability, which could allow local users to conduct unauthorized activities via ipv4/ip_sockglue.c and ipv6/ipv6_sockglue.c (CVE-2005-2555). 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). xattr.c in the ext2 and ext3 file system code does not properly compare the name_index fields when sharing xattr blocks which could prevent ACLs from being applied (CVE-2005-2801). 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 (CVE-2005-2873).

    description Oleg Nesterov discovered a local Denial of Service vulnerability in the timer handling. When a non group-leader thread called exec() to execute a different program while an itimer was pending, the timer expiry would signal the old group leader task, which did not exist any more. This caused a kernel panic. This vulnerability only affects Ubuntu 5.04. (CAN-2005-1913) Al Viro discovered that the sendmsg() function did not sufficiently validate its input data. By calling sendmsg() and at the same time modifying the passed message in another thread, he could exploit this to execute arbitrary commands with kernel privileges. This only affects the amd64 bit platform. (CAN-2005-2490) Al Viro discovered a vulnerability in the raw_sendmsg() function. By calling this function with specially crafted arguments, a local attacker could either read kernel memory contents (leading to information disclosure) or manipulate the hardware state by reading certain IO ports. This vulnerability only affects Ubuntu 5.04. (CAN-2005-2492) Jan Blunck discovered a Denial of Service vulnerability in the procfs interface of the SCSI driver. By repeatedly reading /proc/scsi/sg/devices, a local attacker could eventually exhaust kernel memory. (CAN-2005-2800) A flaw was discovered in the handling of extended attributes on ext2 and ext3 file systems. Under certain condidions, this could prevent the enforcement of Access Control Lists, which eventually could lead to information disclosure, unauthorized program execution, or unauthorized data modification. This does not affect the standard Unix permissions. (CAN-2005-2801) Chad Walstrom discovered a Denial of Service in the ipt_recent module, which can be used in netfilter (Firewall configuration). A remote attacker could exploit this to crash the kernel by sending certain packets (such as an SSH brute-force attack) to a host which uses the 'recent' module. (CAN-2005-2802). 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.

    description 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-2004-1017 Multiple overflows exist in the io_edgeport driver which might be usable as a denial of service attack vector. - CVE-2005-0124 Bryan Fulton reported a bounds checking bug in the coda_pioctl function which may allow local users to execute arbitrary code or trigger a denial of service attack. - CVE-2005-0449 An error in the skb_checksum_help() function from the netfilter framework has been discovered that allows the bypass of packet filter rules or a denial of service attack. - CVE-2005-2457 Tim Yamin discovered that insufficient input validation in the zisofs driver for compressed ISO file systems allows a denial of service attack through maliciously crafted ISO images. - CVE-2005-2490 A buffer overflow in the sendmsg() function allows local users to execute arbitrary code. - CVE-2005-2555 Herbert Xu discovered that the setsockopt() function was not restricted to users/processes with the CAP_NET_ADMIN capability. This allows attackers to manipulate IPSEC policies or initiate a denial of service attack. - CVE-2005-2709 Al Viro discovered a race condition in the /proc handling of network devices. A (local) attacker could exploit the stale reference after interface shutdown to cause a denial of service or possibly execute code in kernel mode. - CVE-2005-2800 Jan Blunck discovered that repeated failed reads of /proc/scsi/sg/devices leak memory, which allows a denial of service attack. - CVE-2005-2973 Tetsuo Handa discovered that the udp_v6_get_port() function from the IPv6 code can be forced into an endless loop, which allows a denial of service attack. - CVE-2005-3044 Vasiliy Averin discovered that the reference counters from sockfd_put() and fput() can be forced into overlapping, which allows a denial of service attack through a NULL pointer dereference. - CVE-2005-3053 Eric Dumazet discovered that the set_mempolicy() system call accepts a negative value for its first argument, which triggers a BUG() assert. This allows a denial of service attack. - CVE-2005-3055 Harald Welte discovered that if a process issues a USB Request Block (URB) to a device and terminates before the URB completes, a stale pointer would be dereferenced. This could be used to trigger a denial of service attack. - CVE-2005-3180 Pavel Roskin discovered that the driver for Orinoco wireless cards clears its buffers insufficiently. This could leak sensitive information into user space. - CVE-2005-3181 Robert Derr discovered that the audit subsystem uses an incorrect function to free memory, which allows a denial of service attack. - CVE-2005-3257 Rudolf Polzer discovered that the kernel improperly restricts access to the KDSKBSENT ioctl, which can possibly lead to privilege escalation. - CVE-2005-3356 Doug Chapman discovered that the mq_open syscall can be tricked into decrementing an internal counter twice, which allows a denial of service attack through a kernel panic. - CVE-2005-3358 Doug Chapman discovered that passing a zero bitmask to the set_mempolicy() system call leads to a kernel panic, which allows a denial of service attack. - CVE-2005-3783 The ptrace code using CLONE_THREAD didn't use the thread group ID to determine whether the caller is attaching to itself, which allows a denial of service attack. - CVE-2005-3784 The auto-reaping of child processes functionality included ptraced-attached processes, which allows denial of service through dangling references. - CVE-2005-3806 Yen Zheng discovered that the IPv6 flow label code modified an incorrect variable, which could lead to memory corruption and denial of service. - CVE-2005-3847 It was discovered that a threaded real-time process, which is currently dumping core can be forced into a dead-lock situation by sending it a SIGKILL signal, which allows a denial of service attack. - CVE-2005-3848 Ollie Wild discovered a memory leak in the icmp_push_reply() function, which allows denial of service through memory consumption. - CVE-2005-3857 Chris Wright discovered that excessive allocation of broken file lock leases in the VFS layer can exhaust memory and fill up the system logging, which allows denial of service. - CVE-2005-3858 Patrick McHardy discovered a memory leak in the ip6_input_finish() function from the IPv6 code, which allows denial of service. - CVE-2005-4605 Karl Janmar discovered that a signedness error in the procfs code can be exploited to read kernel memory, which may disclose sensitive information. - CVE-2005-4618 Yi Ying discovered that sysctl does not properly enforce the size of a buffer, which allows a denial of service attack. - CVE-2006-0095 Stefan Rompf discovered that dm_crypt does not clear an internal struct before freeing it, which might disclose sensitive information. - CVE-2006-0096 It was discovered that the SDLA driver's capability checks were too lax for firmware upgrades. - CVE-2006-0482 Ludovic Courtes discovered that get_compat_timespec() performs insufficient input sanitizing, which allows a local denial of service attack. - CVE-2006-1066 It was discovered that ptrace() on the ia64 architecture allows a local denial of service attack, when preemption is enabled.

description Memory leak in the seq_file implemenetation in the SCSI procfs interface (sg.c) in Linux kernel 2.6.13 and earlier allows local users to cause a denial of service (memory consumption) via certain repeated reads from the /proc/scsi/sg/devices file, which is not properly handled when the next() iterator returns NULL or an error.
