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).

Under certain user-triggerable conditions, a semaphore was not released properly, which caused processes which also attempted to join a key session to hang forever. This only affects Ubuntu 5.04 (Hoary Hedgehog). (CAN-2005-2098) David Howells discovered a local Denial of Service vulnerability in the keyring allocator.

(CAN-2005-2099) Balazs Scheidler discovered a local Denial of Service vulnerability in the xfrm_compile_policy() function.

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).
