SuSE 10 Security Update : Linux Kernel (x86_64) (ZYPP Patch Number 6697)

This script is Copyright (C) 2012-2016 Tenable Network Security, Inc.


Synopsis :

The remote SuSE 10 host is missing a security-related patch.

Description :

This update fixes various bugs and some security issues in the SUSE
Linux Enterprise 10 SP 3 kernel.

The following security issues were fixed: CVE-2009-3939: A sysctl
variable of the megaraid_sas driver was worldwriteable, allowing local
users to cause a denial of service or potential code execution.

- The collect_rx_frame function in
drivers/isdn/hisax/hfc_usb.c in the Linux kernel before
2.6.32-rc7 allows attackers to have an unspecified
impact via a crafted HDLC packet that arrives over ISDN
and triggers a buffer under-read. (CVE-2009-4005)

- A negative offset in a ioctl in the GDTH RAID driver was
fixed. (CVE-2009-3080)

- The fuse_direct_io function in fs/fuse/file.c in the
fuse subsystem in the Linux kernel might allow attackers
to cause a denial of service (invalid pointer
dereference and OOPS) via vectors possibly related to a
memory-consumption attack. (CVE-2009-4021)

- Memory leak in the appletalk subsystem in the Linux
kernel when the appletalk and ipddp modules are loaded
but the ipddp'N' device is not found, allows remote
attackers to cause a denial of service (memory
consumption) via IP-DDP datagrams. (CVE-2009-2903)

- net/1/af_unix.c in the Linux kernel allows local users
to cause a denial of service (system hang) by creating
an abstract-namespace AF_UNIX listening socket,
performing a shutdown operation on this socket, and then
performing a series of connect operations to this
socket. (CVE-2009-3621)

- The tcf_fill_node function in net/sched/cls_api.c in the
netlink subsystem in the Linux kernel 2.6.x before
2.6.32-rc5, and 2.4.37.6 and earlier, does not
initialize a certain tcm__pad2 structure member, which
might allow local users to obtain sensitive information
from kernel memory via unspecified vectors. NOTE: this
issue existed because of an incomplete fix for
CVE-2005-4881. (CVE-2009-3612 / CVE-2005-4881)

- The ATI Rage 128 (aka r128) driver in the Linux kernel
does not properly verify Concurrent Command Engine (CCE)
state initialization, which allows local users to cause
a denial of service (NULL pointer dereference and system
crash) or possibly gain privileges via unspecified ioctl
calls. (CVE-2009-3620)

- The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the
NFSv4 client in the Linux kernel allows remote NFS
servers to cause a denial of service (NULL pointer
dereference and panic) by sending a certain response
containing incorrect file attributes, which trigger
attempted use of an open file that lacks NFSv4 state.
(CVE-2009-3726)

The rio and sx serial multiport card drivers were disabled via a
modprobe blacklist due to severe bugs.
