NASL family Mandriva Local Security Checks NASL id MANDRAKE_MDKSA-2005-220.NASL 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.

This kernel update for SUSE Linux 10.0 contains fixes for XEN, various security fixes and bug fixes. This update includes a more recent snapshot of the upcoming XEN 3.0. Many bugs have been fixed. Stability for x86_64 has been improved. Stability has been improved for SMP, and now both i586 and x86_64 kernels are built with SMP support. It also contains several security fixes : - CVE-2005-3783: A check in ptrace(2) handling that finds out if a process is attaching to itself was incorrect and could be used by a local attacker to crash the machine. - CVE-2005-3784: A check in reaping of terminating child processes did not consider ptrace(2) attached processes and would leave a ptrace reference dangling. This could lead to a local user being able to crash the machine. - CVE-2005-3271: A task leak problem when releasing POSIX timers was fixed. This could lead to local users causing a local denial of service by exhausting system memory. - CVE-2005-3805: A locking problem in POSIX timer handling could be used by a local attacker on a SMP system to deadlock the machine. - CVE-2005-3181: A problem in the Linux auditing code could lead to a memory leak which finally could exhaust system memory of a machine. - CVE-2005-2973: An infinite loop in the IPv6 UDP loopback handling can be easily triggered by a local user and lead to a denial of service. - CVE-2005-3806: A bug in IPv6 flow label handling code could be used by a local attacker to free non-allocated memory and in turn corrupt kernel memory and likely crash the machine. - CVE-2005-3807: A memory kernel leak in VFS lease handling can exhaust the machine memory and so cause a local denial of service. This is seen in regular Samba use and could also be triggered by local attackers. - CVE-2005-3055: Unplugging an user space controlled USB device with an URB pending in user space could crash the kernel. This can be easily triggered by local attacker. - CVE-2005-3180: Fixed incorrect padding in Orinoco wireless driver, which could expose kernel data to the air. - CVE-2005-3044: Missing sockfd_put() calls in routing_ioctl() leaked file handles which in turn could exhaust system memory. - CVE-2005-3527: A race condition in do_coredump in signal.c allows local users to cause a denial of service (machine hang) by triggering a core dump in one thread while another thread has a pending SIGSTOP. last seen 2019-10-28 modified 2005-12-08 plugin id 20282 published 2005-12-08 reporter This script is Copyright (C) 2005-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/20282 title SUSE-SA:2005:067: kernel NASL family Mandriva Local Security Checks NASL id MANDRAKE_MDKSA-2005-219.NASL 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).
