1) Problem Description and Brief Discussion
This kernel update fixes the following security problems in our SUSE
Linux Enterprise Server 9, Novell Linux Desktop 9 and Open Enterprise
Server kernels.
- CVE-2006-2936: The ftdi_sio driver allowed local users to cause a
denial of service (memory consumption) by writing more data to the
serial port than the hardware can handle, which causes the data
to be queued. This requires this driver to be loaded, which only
happens if such a device is plugged in.
- CVE-2006-5871: smbfs when UNIX extensions are enabled,
ignores certain mount options, which could cause clients to use
server-specified UID, GID and MODE settings.
- CVE-2006-6106: Multiple buffer overflows in the cmtp_recv_interopmsg
function in the Bluetooth driver (net/bluetooth/cmtp/capi.c) in the
Linux kernel allowed remote attackers to cause a denial of service
(crash) and possibly execute arbitrary code via CAPI messages with
a large value for the length of the (1) manu (manufacturer) or (2)
serial (serial number) field.
- CVE-2006-6535: The dev_queue_xmit function in Linux kernel 2.6 can
fail before calling the local_bh_disable function, which could
lead to data corruption and "node lockups". This issue might not
be exploitable at all for an attacker.
- CVE-2006-5749: The isdn_ppp_ccp_reset_alloc_state function in
drivers/isdn/isdn_ppp.c in the Linux kernel does not call the
init_timer function for the ISDN PPP CCP reset state timer, which
has unknown attack vectors and results in a system crash.
- CVE-2006-5753: Unspecified vulnerability in the listxattr system
call in Linux kernel, when a "bad inode" is present, allows local
users to cause a denial of service (data corruption) and possibly
gain privileges.
- CVE-2006-5754: The aio_setup_ring function in Linux kernel does not
properly initialize a variable, which allows local users to cause
a denial of service (crash).
- CVE-2007-1357: A denial of service problem against the AppleTalk
protocol was fixed. A remote attacker in the same AppleTalk
network segment could cause the machine to crash if it has AppleTalk
protocol loaded.
Please note that we do not load the AppleTalk protocol by default
and such an attack would only be working within a AppleTalk network,
since the protocol is not routed over the Internet.
- CVE-2007-1592: A local user could affect a double-free of a ipv6
structure potentially causing a local denial of service attack.
- - A local denial of service was fixed in the USB visor driver,
where local attackers could cause a huge amount of kernel
memory to be allocated and so run the machine out of memory.
This is classified as low severity, since local denial
of service using memory consumption are also possible
in other ways.
- CVE-2007-1353: The setsockopt function in the L2CAP and HCI Bluetooth
support in the Linux kernel allows context-dependent attackers to
read kernel memory and obtain sensitive information via unspecified
vectors involving the copy_from_user function accessing an
uninitialized stack buffer.
- CVE-2006-7203: The compat_sys_mount function in fs/compat.c allows
local users to cause a denial of service (NULL pointer dereference
and oops) by mounting a smbfs file system in compatibility mode
("mount -t smbfs").
