Scientific Linux Security Update : kernel on SL5.x i386/x86_64

medium Nessus Plugin ID 60351
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

These new kernel packages fix the following security issues :

A flaw was found in the virtual filesystem (VFS). An unprivileged local 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 Xen PAL emulation on Intel 64 platforms. A guest Hardware-assisted virtual machine (HVM) could read the arbitrary physical memory of the host system, which could make information available to unauthorized users. (CVE-2007-6416, Important)

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, potentially containing sensitive information. (CVE-2007-6206, Moderate)

A buffer overflow flaw was found in the CIFS virtual file system. A remote,authenticated user could issue a request that could lead to a denial of service. (CVE-2007-5904, Moderate)

A flaw was found in the 'sysfs_readdir' function. A local user could create a race condition which would cause a denial of service (kernel oops). (CVE-2007-3104, Moderate)

As well, these updated packages fix the following bugs :

- running the 'strace -f' command caused strace to hang, without displaying information about child processes.

- unmounting an unresponsive, interruptable NFS mount, for example, one mounted with the 'intr' option, may have caused a system crash.

- a bug in the s2io.ko driver prevented VLAN devices from being added. Attempting to add a device to a VLAN, for example, running the 'vconfig add [device-name] [vlan-id]' command caused vconfig to fail.

- tux used an incorrect open flag bit. This caused problems when building packages in a chroot environment, such as mock, which is used by the koji build system.

Solution

Update the affected packages.
