Mandriva Linux Security Advisory MDKSA-2005:218
http://www.mandriva.com/security/
_______________________________________________________________________
Package : kernel
Date : November 30, 2005
Affected: Corporate 3.0, Multi Network Firewall 2.0
_______________________________________________________________________
Problem Description:
Multiple vulnerabilities in the Linux 2.6 kernel have been discovered
and corrected in this update:
An integer overflow in vc_resize (
CAN-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 (
CAN-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).
The netfilter/iptables module in versions prior to 2.6.8.1 allow remote
attackers to cause a DoS (crash) or bypass firewall rules via crafted
packets, which are not properly handled by skb_checksum_help function
(CVE-2005-0449).
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).
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).
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).
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).
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 following non-security fixes are also applied:
Support for the arp_ignore and arp_announce sysctls were added to the
Corporate 3 kernels (bugzilla #16346).
The provided packages are patched to fix these vulnerabilities. All
users are encouraged to upgrade to these updated kernels.
