SUSE-SA:2006:057: 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:2006:057 (kernel).

Various security problems were found and fixed in the Linux kernel.

We have released updates for following distributions:
- SUSE Linux Enterprise Server 9 (on September 21st)
- SUSE Linux Enterprise 10 (on September 26th)
- SUSE Linux 9.2 up to 10.1 (on September 14th)

The SUSE Linux Enterprise Server 10 kernel for the S/390 platform is
still pending due to platform specific issues found in QA and waiting
for further analysis.

Following security issues have been addressed:
- CVE-2006-3745: A double user space copy in a SCTP ioctl allows
local attackers to overflow a buffer in the kernel,
potentially allowing code execution and privilege

- CVE-2006-4093: Local attackers were able to crash PowerPC systems
with PPC970 processor using a not correctly disabled
privileged instruction ('attn').

- CVE-2006-3468: Remote attackers able to access an NFS of a ext2 or
ext3 filesystem can cause a denial of service (file
system panic) via a crafted UDP packet with a V2
look up procedure that specifies a bad file handle
(inode number), which triggers an error and causes
an exported directory to be remounted read-only.

- Matthias Andree reported a deadlock in the NFS lockd to us, where
a remote attacker with access to lockd was able to at least crash
the lockd kernel process and so render NFS exports from this server
unusable. This problem existed only in the SUSE Linux 9.2 up to
10.0 kernels.

The SUSE Linux Enterprise kernels also received a number of bugfixes,
not listed here (please refer to the Novell TID pages listed below).
