SUSE-SA:2004:028: kernel Vulnerability Scan

Vulnerability Scan Summary
Check for the version of the kernel package

Detailed Explanation for this Vulnerability Test

The remote host is missing the patch for the advisory SUSE-SA:2004:028 (kernel).

Various signedness issues and integer overflows have been fixed within
kNFSd and the XDR decode functions of kernel 2.6.
These bugs can be triggered remotely by sending a package with a trusted
source IP address and a write request with a size greater then 2^31.
The result will be a kernel Oops, it is unknown if this bug is otherwise
exploitable yet.
Kernel 2.4 nfsd code is different but may suffer from the same
Additionally a local denial-of-service condition via /dev/ptmx, which
affects kernel 2.6 only has been fixed. Thanks to Jan Engelhardt for
reporting this issue to us.
