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.

These new kernel packages contain fixes for the following security issues :

  - A flaw was found in the backported stack unwinder fixes     in Red Hat Enterprise Linux 5. On AMD64 and Intel 64     platforms, a local user could trigger this flaw and     cause a denial of service. (CVE-2007-4574, Important)

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

  - A flaw was found in the Distributed Lock Manager (DLM)     in the cluster manager. This allowed a remote user who     is able to connect to the DLM port to cause a denial of     service. (CVE-2007-3380, Important)

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

  - A flaw was found in the prio_tree handling of the     hugetlb support that allowed a local user to cause a     denial of service. This only affected kernels with     hugetlb support. (CVE-2007-4133, Moderate)

  - A flaw was found in the eHCA driver on PowerPC     architectures that allowed a local user to access 60k of     physical address space. This address space could contain     sensitive information. (CVE-2007-3850, Moderate)

  - A flaw was found in ptrace support that allowed a local     user to cause a denial of service via a NULL pointer     dereference. (CVE-2007-3731, Moderate)

  - A flaw was found in the usblcd driver that allowed a     local user to cause a denial of service by writing data     to the device node. To exploit this issue, write access     to the device node was needed. (CVE-2007-3513, Moderate)

  - A flaw was found in the random number generator     implementation that allowed a local user to cause a     denial of service or possibly gain privileges. If the     root user raised the default wakeup threshold over the     size of the output pool, this flaw could be exploited.
    (CVE-2007-3105, Low)

In addition to the security issues described above, several bug fixes preventing possible system crashes and data corruption were also included.

Updated kernel packages that fix various security issues in the Red Hat Enterprise Linux 5 kernel are now available.

This update 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 following security issues :

* A flaw was found in the backported stack unwinder fixes in Red Hat Enterprise Linux 5. On AMD64 and Intel 64 platforms, a local user could trigger this flaw and cause a denial of service. (CVE-2007-4574, Important)

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

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

* A flaw was found in the prio_tree handling of the hugetlb support that allowed a local user to cause a denial of service. This only affected kernels with hugetlb support. (CVE-2007-4133, Moderate)

* A flaw was found in the eHCA driver on PowerPC architectures that allowed a local user to access 60k of physical address space. This address space could contain sensitive information. (CVE-2007-3850, Moderate)

* A flaw was found in ptrace support that allowed a local user to cause a denial of service via a NULL pointer dereference.
(CVE-2007-3731, Moderate)

* A flaw was found in the usblcd driver that allowed a local user to cause a denial of service by writing data to the device node. To exploit this issue, write access to the device node was needed.
(CVE-2007-3513, Moderate)

(CVE-2007-3105, Low)

In addition to the security issues described above, several bug fixes preventing possible system crashes and data corruption were also included.

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