Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This kernel update fixes the following security problems :

++ CVE-2007-3104: The sysfs_readdir function in the Linux kernel 2.6 allows local users to cause a denial of service (kernel OOPS) by dereferencing a NULL pointer to an inode in a dentry.

++ CVE-2007-4997: A 2 byte buffer underflow in the ieee80211 stack was fixed, which might be used by attackers in the local WLAN reach to crash the machine.

++ CVE-2007-3740: The CIFS filesystem, when Unix extension support is enabled, did not honor the umask of a process, which allowed local users to gain privileges.

++ CVE-2007-4573: It was possible for local user to become root by exploiting a bug in the IA32 system call emulation. This problem affects the x86_64 platform only, on all distributions.

This problem was fixed for regular kernels, but had not been fixed for the XEN kernels. This update fixes the problem also for the XEN kernels.

++ CVE-2007-4308: The (1) aac_cfg_open and (2) aac_compat_ioctl functions in the SCSI layer ioctl path in aacraid did not check permissions for ioctls, which might have allowed local users to cause a denial of service or gain privileges.

++ CVE-2007-3843: The Linux kernel checked the wrong global variable for the CIFS sec mount option, which might allow remote attackers to spoof CIFS network traffic that the client configured for security signatures, as demonstrated by lack of signing despite sec=ntlmv2i in a SetupAndX request.

++ CVE-2007-5904: Multiple buffer overflows in CIFS VFS in the Linux kernel allowed remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via long SMB responses that trigger the overflows in the SendReceive function.

This requires the attacker to mis-present / replace a CIFS server the client machine is connected to.

++ CVE-2007-6063: Buffer overflow in the isdn_net_setcfg function in isdn_net.c in the Linux kernel allowed local users to have an unknown impact via a crafted argument to the isdn_ioctl function.

Furthermore, this kernel catches up to the SLE 10 state of the kernel, with numerous additional fixes.

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.

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.

Updated kernel packages that fix a number of security issues are now available for Red Hat Enterprise Linux 2.1 running on 32-bit architectures.

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 was found in the IPv4 forwarding base. This could allow a local, unprivileged user to cause a denial of service. (CVE-2007-2172, Important)

* a flaw was found in the handling of process death signals. This allowed a local, unprivileged user to send arbitrary signals to the suid-process executed by that user. Successful exploitation of this flaw depends on the structure of the suid-program and its signal handling. (CVE-2007-3848, Important)

* when accessing kernel memory locations, certain Linux kernel drivers registering a fault handler did not perform required range checks. A local, unprivileged user could use this flaw to gain read or write access to arbitrary kernel memory, or possibly cause a denial of service. (CVE-2008-0007, 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, unprivileged user to bypass intended capability restrictions. (CVE-2008-3525, Important)

* a flaw was found in the way files were written using truncate() or ftruncate(). This could allow a local, unprivileged user to acquire the privileges of a different group and obtain access to sensitive information. (CVE-2008-4210, Important)

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

* a flaw was found in the aacraid SCSI driver. This allowed a local, unprivileged user to make ioctl calls to the driver which should otherwise be restricted to privileged users. (CVE-2007-4308, Moderate)

* two buffer overflow flaws were found in the Integrated Services Digital Network (ISDN) subsystem. A local, unprivileged user could use these flaws to cause a denial of service. (CVE-2007-6063, CVE-2007-6151, Moderate)

* a flaw was found in the way core dump files were created. If a local, unprivileged user could make a root-owned process dump a core file into a user-writable directory, the user could gain read access to that core file, potentially compromising sensitive information.
(CVE-2007-6206, Moderate)

* a deficiency was found in the Linux kernel virtual file system (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)
