Package : linux-2.6.24
Vulnerability : privilege escalation/denial of service/sensitive memory leak
Problem type : local/remote
Debian-specific: no

CVE-2009-3889 CVE-2009-4005 CVE-2009-4020 CVE-2009-4021

CVE-2010-0415 CVE-2010-0622

NOTE: This kernel update marks the final planned kernel security
update for the 2.6.24 kernel in the Debian release 'etch'. Although
security support for 'etch' officially ended on Feburary 15th, 2010,
this update was already in preparation before that date.

Several vulnerabilities have been discovered in the Linux kernel that
may lead to a denial of service, sensitive memory leak or privilege
escalation. The Common Vulnerabilities and Exposures project
identifies the following problems:

CVE-2009-2691

Steve Beattie and Kees Cook reported an information leak in the
maps and smaps files available under /proc. Local users may be
able to read this data for setuid processes while the ELF binary
is being loaded.

CVE-2009-2695

Eric Paris provided several fixes to increase the protection
provided by the mmap_min_addr tunable against NULL pointer
dereference vulnerabilities.

CVE-2009-3080

Dave Jones reported an issue in the gdth SCSI driver. A missing
check for negative offsets in an ioctl call could be exploited by
local users to create a denial of service or potentially gain
elevated privileges.

CVE-2009-3726

Trond Myklebust reported an issue where a malicious NFS server
could cause a denial of service condition on its clients by
returning incorrect attributes during an open call.

CVE-2009-3889

Joe Malicki discovered an issue in the megaraid_sas driver.
Insufficient permissions on the sysfs dbg_lvl interface allow
local users to modify the debug logging behavior.

CVE-2009-4005

Roel Kluin discovered an issue in the hfc_usb driver, an ISDN
driver for Colognechip HFC-S USB chip. A potential read overflow
exists which may allow remote users to cause a denial of service
condition (oops).

CVE-2009-4020

Amerigo Wang discovered an issue in the HFS filesystem that would
allow a denial of service by a local user who has sufficient
privileges to mount a specially crafted filesystem.

CVE-2009-4021

Anana V. Avati discovered an issue in the fuse subsystem. If the
system is sufficiently low on memory, a local user can cause the
kernel to dereference an invalid pointer resulting in a denial of
service (oops) and potentially an escalation of privileges.

CVE-2009-4138

Jay Fenlason discovered an issue in the firewire stack that allows
local users to cause a denial of service (oops or crash) by making
a specially crafted ioctl call.

CVE-2009-4308

Ted Ts'o discovered an issue in the ext4 filesystem that allows
local users to cause a denial of service (NULL pointer
dereference). For this to be exploitable, the local user must
have sufficient privileges to mount a filesystem.

CVE-2009-4536 & CVE-2009-4538

Fabian Yamaguchi reported issues in the e1000 and e1000e drivers
for Intel gigabit network adapters which allow remote users to
bypass packet filters using specially crafted Ethernet frames.

CVE-2010-0003

Andi Kleen reported a defect which allows local users to gain read
access to memory reachable by the kernel when the
print-fatal-signals option is enabled. This option is disabled by
default.

CVE-2010-0007

Florian Westphal reported a lack of capability checking in the
ebtables netfilter subsystem. If the ebtables module is loaded,
local users can add and modify ebtables rules.

CVE-2010-0291

Al Viro reported several issues with the mmap/mremap system calls
that allow local users to cause a denial of service (system panic)
or obtain elevated privileges.

CVE-2010-0410

Sebastian Krahmer discovered an issue in the netlink connector
subsystem that permits local users to allocate large amounts of
system memory resulting in a denial of service (out of memory).

CVE-2010-0415

Ramon de Carvalho Valle discovered an issue in the sys_move_pages
interface, limited to amd64, ia64 and powerpc64 flavors in Debian.
Local users can exploit this issue to cause a denial of service
(system crash) or gain access to sensitive kernel memory.

CVE-2010-0622

Jermome Marchand reported an issue in the futex subsystem that
allows a local user to force an invalid futex state which results
in a denial of service (oops).

For the oldstable distribution (etch), this problem has been fixed in
version 2.6.24-6~etchnhalf.9etch3.

We recommend that you upgrade your linux-2.6.24 packages.

Upgrade instructions

[SECURITY] [DSA 2004-1] New samba packages fix several vulnerabilities

Package : samba
Vulnerability : several
Problem type : local
Debian-specific: no
CVE Id(s) : CVE-2009-3297 CVE-2010-0547

Two local vulnerabilities have been discovered in samba, a SMB/CIFS file,
print, and login server for Unix. The Common Vulnerabilities and
Exposures project identifies the following problems:

CVE-2009-3297

Ronald Volgers discovered that a race condition in mount.cifs
allows local users to mount remote filesystems over arbitrary
mount points.

CVE-2010-0547

Jeff Layton discovered that missing input sanitising in mount.cifs
allows denial of service by corrupting /etc/mtab.

For the stable distribution (lenny), these problems have been fixed in
version 2:3.2.5-4lenny9.

For the unstable distribution (sid), these problems have been fixed in
version 2:3.4.5~dfsg-2.

We recommend that you upgrade your samba packages.
