Vulnerability Assessment Details
Check for the version of the kernel package
Detailed Explanation for this Vulnerability Assessment
The remote host is missing the patch for the advisory FEDORA-2007-225 (kernel).
The kernel package contains the Linux kernel (vmlinuz), the core of any
Linux operating system. The kernel handles the basic functions
of the operating system: memory allocation, process allocation, device
input and output, etc.
The key serial number collision avoidance code in the
key_alloc_serial function in Linux kernel 2.6.9 up to 2.6.20
permits remote attackers to cause a denial of service (crash)
via vectors that trigger a null dereference, as originally
reported as 'spinlock CPU recursion.'
Major rebase to upstream linux kernel 18.104.22.168:
This update also introduces 'kernel-debug', a variant with
additional debugging options enabled. These kernels may run
with lower performance and increased memory overhead than
the non-debug variants.
