From Red Hat Security Advisory 2008:0973 :

Updated kernel packages that resolve several security issues and fix various bugs are now available for Red Hat Enterprise Linux 3.

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

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update addresses the following security issues :

* Tavis Ormandy discovered a deficiency in the Linux kernel 32-bit and 64-bit emulation. This could allow a local, unprivileged user to prepare and run a specially crafted binary which would use this deficiency to leak uninitialized and potentially sensitive data.
(CVE-2008-0598, Important)

* a possible kernel memory leak was found in the Linux kernel Simple Internet Transition (SIT) INET6 implementation. This could allow a local, unprivileged user to cause a denial of service. (CVE-2008-2136, Important)

* missing capability checks were found in the SBNI WAN driver which could allow a local user to bypass intended capability restrictions.
(CVE-2008-3525, Important)

* the do_truncate() and generic_file_splice_write() functions did not clear the setuid and setgid bits. This could allow a local, unprivileged user to obtain access to privileged information.
(CVE-2008-4210, Important)

* a buffer overflow flaw was found in Integrated Services Digital Network (ISDN) subsystem. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2007-6063, Moderate)

* multiple NULL pointer dereferences were found in various Linux kernel network drivers. These drivers were missing checks for terminal validity, which could allow privilege escalation. (CVE-2008-2812, Moderate)

* a deficiency was found in the Linux kernel virtual filesystem (VFS) implementation. This could allow a local, unprivileged user to attempt file creation within deleted directories, possibly causing a denial of service. (CVE-2008-3275, Moderate)

This update also fixes the following bugs :

* the incorrect kunmap function was used in nfs_xdr_readlinkres.
kunmap() was used where kunmap_atomic() should have been. As a consequence, if an NFSv2 or NFSv3 server exported a volume containing a symlink which included a path equal to or longer than the local system's PATH_MAX, accessing the link caused a kernel oops. This has been corrected in this update.

* mptctl_gettargetinfo did not check if pIoc3 was NULL before using it as a pointer. This caused a kernel panic in mptctl_gettargetinfo in some circumstances. A check has been added which prevents this.

* lost tick compensation code in the timer interrupt routine triggered without apparent cause. When running as a fully-virtualized client, this spurious triggering caused the 64-bit version of Red Hat Enterprise Linux 3 to present highly inaccurate times. With this update the lost tick compensation code is turned off when the operating system is running as a fully-virtualized client under Xen or VMware(r).

All Red Hat Enterprise Linux 3 users should install this updated kernel which addresses these vulnerabilities and fixes these bugs.

a. Service Console update for DHCP and third-party library update    for DHCP client.

   DHCP is an Internet-standard protocol by which a computer can be    connected to a local network, ask to be given configuration    information, and receive from a server enough information to    configure itself as a member of that network.

   A stack-based buffer overflow in the script_write_params method in    ISC DHCP dhclient allows remote DHCP servers to execute arbitrary    code via a crafted subnet-mask option.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-0692 to this issue.

   An insecure temporary file use flaw was discovered in the DHCP    daemon's init script ('/etc/init.d/dhcpd'). A local attacker could    use this flaw to overwrite an arbitrary file with the output of the    'dhcpd -t' command via a symbolic link attack, if a system    administrator executed the DHCP init script with the 'configtest',    'restart', or 'reload' option.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-1893 to this issue.

b. Updated Service Console package kernel

   Service Console package kernel update to version    kernel-2.4.21-58.EL.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the names CVE-2008-4210, CVE-2008-3275, CVE-2008-0598,    CVE-2008-2136, CVE-2008-2812, CVE-2007-6063, CVE-2008-3525 to the    security issues fixed in kernel-2.4.21-58.EL

c. JRE Security Update

   JRE update to version 1.5.0_18, which addresses multiple security    issues that existed in earlier releases of JRE.

   The Common Vulnerabilities and Exposures project (cve.mitre.org) has    assigned the following names to the security issues fixed in    JRE 1.5.0_17: CVE-2008-2086, CVE-2008-5347, CVE-2008-5348,    CVE-2008-5349, CVE-2008-5350, CVE-2008-5351, CVE-2008-5352,    CVE-2008-5353, CVE-2008-5354, CVE-2008-5356, CVE-2008-5357,    CVE-2008-5358, CVE-2008-5359, CVE-2008-5360, CVE-2008-5339,    CVE-2008-5342, CVE-2008-5344, CVE-2008-5345, CVE-2008-5346,    CVE-2008-5340, CVE-2008-5341, CVE-2008-5343, and CVE-2008-5355.

   The Common Vulnerabilities and Exposures project (cve.mitre.org) has    assigned the following names to the security issues fixed in    JRE 1.5.0_18: CVE-2009-1093, CVE-2009-1094, CVE-2009-1095,    CVE-2009-1096, CVE-2009-1097, CVE-2009-1098, CVE-2009-1099,    CVE-2009-1100, CVE-2009-1101, CVE-2009-1102, CVE-2009-1103,    CVE-2009-1104, CVE-2009-1105, CVE-2009-1106, and CVE-2009-1107.

Updated kernel packages that fix various security issues and several bugs are now available for Red Hat Enterprise Linux 5.

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

The kernel packages contain the Linux kernel, the core of any Linux operating system.

These updated packages fix the following security issues :

* a flaw in the hypervisor for hosts running on Itanium architectures allowed an Intel VTi domain to read arbitrary physical memory from other Intel VTi domains, which could make information available to unauthorized users. (CVE-2007-6207, Important)

* two buffer overflow flaws were found in ISDN subsystem. A local unprivileged user could use these flaws to cause a denial of service.
(CVE-2007-5938: Important, CVE-2007-6063: Moderate)

* a possible NULL pointer dereference was found in the subsystem used for showing CPU information, as used by CHRP systems on PowerPC architectures. This may have allowed a local unprivileged user to cause a denial of service (crash). (CVE-2007-6694, Moderate)

* a flaw was found in the handling of zombie processes. A local user could create processes that would not be properly reaped, possibly causing a denial of service. (CVE-2006-6921, Moderate)

As well, these updated packages fix the following bugs :

* a bug was found in the Linux kernel audit subsystem. When the audit daemon was setup to log the execve system call with a large number of arguments, the kernel could run out of memory, causing a kernel panic.

* on IBM System z architectures, using the IBM Hardware Management Console to toggle IBM FICON channel path ids (CHPID) caused a file ID miscompare, possibly causing data corruption.

* when running the IA-32 Execution Layer (IA-32EL) or a Java VM on Itanium architectures, a bug in the address translation in the hypervisor caused the wrong address to be registered, causing Dom0 to hang.

* on Itanium architectures, frequent Corrected Platform Error errors may have caused the hypervisor to hang.

* when enabling a CPU without hot plug support, routines for checking the presence of the CPU were missing. The CPU tried to access its own resources, causing a kernel panic.

* after updating to kernel-2.6.18-53.el5, a bug in the CCISS driver caused the HP Array Configuration Utility CLI to become unstable, possibly causing a system hang, or a kernel panic.

* a bug in NFS directory caching could have caused different hosts to have different views of NFS directories.

* on Itanium architectures, the Corrected Machine Check Interrupt masked hot-added CPUs as disabled.

* when running Oracle database software on the Intel 64 and AMD64 architectures, if an SGA larger than 4GB was created, and had hugepages allocated to it, the hugepages were not freed after database shutdown.

* in a clustered environment, when two or more NFS clients had the same logical volume mounted, and one of them modified a file on the volume, NULL characters may have been inserted, possibly causing data corruption.

These updated packages resolve several severe issues in the lpfc driver :

* a system hang after LUN discovery.

* a general fault protection, a NULL pointer dereference, or slab corruption could occur while running a debug on the kernel.

* the inability to handle kernel paging requests in 'lpfc_get_scsi_buf'.

* erroneous structure references caused certain FC discovery routines to reference and change 'lpfc_nodelist' structures, even after they were freed.

* the lpfc driver failed to interpret certain fields correctly, causing tape backup software to fail. Tape drives reported 'Illegal Request'.

* the lpfc driver did not clear structures correctly, resulting in SCSI I/Os being rejected by targets, and causing errors.

Red Hat Enterprise Linux 5 users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.

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

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

The kernel packages contain the Linux kernel, the core of any Linux operating system.

These updated kernel packages fix the following security issues :

A flaw was found in the virtual filesystem (VFS). A local unprivileged user could truncate directories to which they had write permission;
this could render the contents of the directory inaccessible.
(CVE-2008-0001, Important)

A flaw was found in the implementation of ptrace. A local unprivileged user could trigger this flaw and possibly cause a denial of service (system hang). (CVE-2007-5500, Important)

A flaw was found in the way the Red Hat Enterprise Linux 4 kernel handled page faults when a CPU used the NUMA method for accessing memory on Itanium architectures. A local unprivileged user could trigger this flaw and cause a denial of service (system panic).
(CVE-2007-4130, Important)

A possible NULL pointer dereference was found in the chrp_show_cpuinfo function when using the PowerPC architecture. This may have allowed a local unprivileged user to cause a denial of service (crash).
(CVE-2007-6694, Moderate)

A flaw was found in the way core dump files were created. If a local user can get a root-owned process to dump a core file into a directory, which the user has write access to, they could gain read access to that core file. This could potentially grant unauthorized access to sensitive information. (CVE-2007-6206, Moderate)

Two buffer overflow flaws were found in the Linux kernel ISDN subsystem. A local unprivileged user could use these flaws to cause a denial of service. (CVE-2007-6063, CVE-2007-6151, Moderate)

As well, these updated packages fix the following bug :

* when moving volumes that contain multiple segments, and a mirror segment is not the first in the mapping table, running the 'pvmove /dev/[device] /dev/[device]' command caused a kernel panic. A 'kernel:
Unable to handle kernel paging request at virtual address [address]' error was logged by syslog.

Red Hat Enterprise Linux 4 users are advised to upgrade to these updated packages, which contain backported patches to resolve these issues.

All Red Hat Enterprise Linux 3 users should install this updated kernel which addresses these vulnerabilities and fixes these bugs.

The minix filesystem did not properly validate certain filesystem values. If a local attacker could trick the system into attempting to mount a corrupted minix filesystem, the kernel could be made to hang for long periods of time, resulting in a denial of service. This was only vulnerable in Ubuntu 7.04 and 7.10. (CVE-2006-6058)

The signal handling on PowerPC systems using HTX allowed local users to cause a denial of service via floating point corruption. This was only vulnerable in Ubuntu 6.10 and 7.04. (CVE-2007-3107)

The Linux kernel did not properly validate the hop-by-hop IPv6 extended header. Remote attackers could send a crafted IPv6 packet and cause a denial of service via kernel panic. This was only vulnerable in Ubuntu 7.04. (CVE-2007-4567)

The JFFS2 filesystem with ACL support enabled did not properly store permissions during inode creation and ACL setting. Local users could possibly access restricted files after a remount. This was only vulnerable in Ubuntu 7.04 and 7.10. (CVE-2007-4849)

Chris Evans discovered an issue with certain drivers that use the ieee80211_rx function. Remote attackers could send a crafted 802.11 frame and cause a denial of service via crash. This was only vulnerable in Ubuntu 7.04 and 7.10. (CVE-2007-4997)

Alex Smith discovered an issue with the pwc driver for certain webcam devices. A local user with physical access to the system could remove the device while a userspace application had it open and cause the USB subsystem to block. This was only vulnerable in Ubuntu 7.04.
(CVE-2007-5093)

Scott James Remnant discovered a coding error in ptrace. Local users could exploit this and cause the kernel to enter an infinite loop.
This was only vulnerable in Ubuntu 7.04 and 7.10. (CVE-2007-5500)

It was discovered that the Linux kernel could dereference a NULL pointer when processing certain IPv4 TCP packets. A remote attacker could send a crafted TCP ACK response and cause a denial of service via crash. This was only vulnerable in Ubuntu 7.10. (CVE-2007-5501)

Warren Togami discovered that the hrtimer subsystem did not properly check for large relative timeouts. A local user could exploit this and cause a denial of service via soft lockup. (CVE-2007-5966)

Venustech AD-LAB discovered a buffer overflow in the isdn net subsystem. This issue is exploitable by local users via crafted input to the isdn_ioctl function. (CVE-2007-6063)

It was discovered that the isdn subsystem did not properly check for NULL termination when performing ioctl handling. A local user could exploit this to cause a denial of service. (CVE-2007-6151)

Blake Frantz discovered that when a root process overwrote an existing core file, the resulting core file retained the previous core file's ownership. Local users could exploit this to gain access to sensitive information. (CVE-2007-6206)

Hugh Dickins discovered the when using the tmpfs filesystem, under rare circumstances, a kernel page may be improperly cleared. A local user may be able to exploit this and read sensitive kernel data or cause a denial of service via crash. (CVE-2007-6417)

Bill Roman discovered that the VFS subsystem did not properly check access modes. A local user may be able to gain removal privileges on directories. (CVE-2008-0001).

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