http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.19.5

CVE-2007-0772: Summary: The Linux kernel before 2.6.20.1 allows remote
attackers to cause a denial of service (oops) via a crafted NFSACL 2
ACCESS request that triggers a free of an incorrect pointer.

CVE-2006-5753: Summary: 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 via unknown vectors. 

Fixed broken SCSI CDROM IOCTLs. Added Xen, which was missing from
1.2911.6.3

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."

"Updated kernel packages that fix several security issues in the Red
Hat Enterprise Linux 4 kernel are now available.

This security advisory has been rated as having important security
impact by the Red Hat Security Response Team.

The Linux kernel handles the basic functions of the operating system.

These new kernel packages contain fixes for the security issues
described below :

* a flaw in the get_fdb_entries function of the network bridging
support that allowed a local user to cause a denial of service (crash)
or allow a potential privilege escalation (CVE-2006-5751, Important)

* an information leak in the _block_prepare_write function that
allowed a local user to read kernel memory (CVE-2006-4813, Important)

* an information leak in the copy_from_user() implementation on s390
and s390x platforms that allowed a local user to read kernel memory
(CVE-2006-5174, Important)

* a flaw in the handling of /proc/net/ip6_flowlabel that allowed a
local user to cause a denial of service (infinite loop)
(CVE-2006-5619, Important)

* a flaw in the AIO handling that allowed a local user to cause a
denial of service (panic) (CVE-2006-5754, Important)

* a race condition in the mincore system core that allowed a local
user to cause a denial of service (system hang) (CVE-2006-4814,
Moderate)

* a flaw in the ELF handling on ia64 and sparc architectures which
triggered a cross-region memory mapping and allowed a local user to
cause a denial of service (CVE-2006-4538, Moderate)

* a flaw in the dev_queue_xmit function of the network subsystem that
allowed a local user to cause a denial of service (data corruption)
(CVE-2006-6535, Moderate)

* a flaw in the handling of CAPI messages over Bluetooth that allowed
a remote system to cause a denial of service or potential code
execution. This flaw is only exploitable if a privileged user
establishes a connection to a malicious remote device (CVE-2006-6106,
Moderate)

* a flaw in the listxattr system call that allowed a local user to
cause a denial of service (data corruption) or potential privilege
escalation. To successfully exploit this flaw the existence of a bad
inode is required first (CVE-2006-5753, Moderate)

* a flaw in the __find_get_block_slow function that allowed a local
privileged user to cause a denial of service (CVE-2006-5757, Low)

* various flaws in the supported filesystems that allowed a local
privileged user to cause a denial of service (CVE-2006-5823,
CVE-2006-6053, CVE-2006-6054, CVE-2006-6056, Low)

In addition to the security issues described above, fixes for the
following bugs were included :

* initialization error of the tg3 driver with some BCM5703x network
card

* a memory leak in the audit subsystem

* x86_64 nmi watchdog timeout is too short

* ext2/3 directory reads fail intermittently

Red Hat would like to thank Dmitriy Monakhov and Kostantin Khorenko
for reporting issues fixed in this erratum.

All Red Hat Enterprise Linux 4 users are advised to upgrade their
kernels to the packages associated with their machine architecture and
configurations as listed in this erratum."

establishes a connection to a malicious remote device (CVE-2006-6106,
Moderate)

* a flaw in the listxattr system call that allowed a local user to
cause a denial of service (data corruption) or potential privilege
escalation. To successfully exploit this flaw the existence of a bad
inode is required first (CVE-2006-5753, Moderate)

* a flaw in the __find_get_block_slow function that allowed a local
privileged user to cause a denial of service (CVE-2006-5757, Low)

* various flaws in the supported filesystems that allowed a local
privileged user to cause a denial of service (CVE-2006-5823,
CVE-2006-6053, CVE-2006-6054, CVE-2006-6056, Low)

In addition to the security issues described above, fixes for the
following bugs were included :

* initialization error of the tg3 driver with some BCM5703x network
card

* a memory leak in the audit subsystem

* x86_64 nmi watchdog timeout is too short

* ext2/3 directory reads fail intermittently

Red Hat would like to thank Dmitriy Monakhov and Kostantin Khorenko
for reporting issues fixed in this erratum.

All Red Hat Enterprise Linux 4 users are advised to upgrade their
kernels to the packages associated with their machine architecture and
configurations as listed in this erratum."

"Some vulnerabilities were discovered and corrected in the Linux 2.6
kernel :

The isdn_ppp_ccp_reset_alloc_state function in drivers/isdn/isdn_ppp.c
in the Linux 2.4 kernel before 2.4.34-rc4, as well as the 2.6 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-2006-5749)

The listxattr syscall can corrupt user space under certain
circumstances. The problem seems to be related to signed/unsigned
conversion during size promotion. (CVE-2006-5753)

The ext3fs_dirhash function in Linux kernel 2.6.x allows local users
to cause a denial of service (crash) via an ext3 stream with malformed
data structures. (CVE-2006-6053)

The mincore function in the Linux kernel before 2.4.33.6, as well as
the 2.6 kernel, does not properly lock access to user space, which has
unspecified impact and attack vectors, possibly related to a deadlock.
(CVE-2006-4814)

The provided packages are patched to fix these vulnerabilities. All
users are encouraged to upgrade to these updated kernels immediately
and reboot to effect the fixes.

In addition to these security fixes, other fixes have been included
such as :

  - Add Ralink RT2571W/RT2671 WLAN USB support (rt73 module)
    - Fix sys_msync() to report -ENOMEM as before when an
    unmapped area falls within its range, and not to
    overshoot (LSB regression) - Avoid disk sector_t
    overflow for >2TB ext3 filesystem - USB: workaround to
    fix HP scanners detection (#26728) - USB: unusual_devs.h
    for Sony floppy (#28378) - Add preliminary ICH9 support
    - Add TI sd card reader support - Add RT61 driver - KVM
    update - Fix bttv vbi offset
