Scientific Linux Security Update : kernel on SL4.x i386/x86_64
medium Nessus Plugin ID 60372

Synopsis
The remote Scientific Linux host is missing one or more security updates.Description
These updated kernel packages fix the following security issue :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)
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 out memory while attempting to create audit log messages. This could cause a kernel panic. In these updated packages, large audit messages are split into acceptable sizes, which resolves this issue.
- on certain Intel chipsets, it was not possible to load the acpiphp module using the 'modprobe acpiphp' command.
Because the acpiphp module did not recurse across PCI bridges, hardware detection for PCI hot plug slots failed. In these updated packages, hardware detection works correctly.
- on IBM System z architectures that run the IBM z/VM hypervisor, the IBM eServer zSeries HiperSockets network interface (layer 3) allowed ARP packets to be sent and received, even when the 'NOARP' flag was set. These ARP packets caused problems for virtual machines.
- it was possible for the iounmap function to sleep while holding a lock. This may have caused a deadlock for drivers and other code that uses the iounmap function.
In these updated packages, the lock is dropped before the sleep code is called, which resolves this issue.
