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

medium Nessus Plugin ID 60351

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.
