SUSE-SA:2005:003: kernel

Vulnerability Assessment Summary
Check for the version of the kernel package

Detailed Explanation for this Vulnerability Assessment

The remote host is missing the patch for the advisory SUSE-SA:2005:003 (kernel).

Several exploitable security problems were identified and fixed in
the Linux kernel, the core of every SUSE Linux product.

- Due to missing locking in the sys_uselib system call a local attacker
can gain root access. This was found by Paul Starzetz and is tracked
by the Mitre CVE ID CVE-2004-1235.

- Paul Starzetz also found a race condition in SMP page table handling
which could lead to a local attacker gaining root access on SMP
machines. This is tracked by the Mitre CVE ID CVE-2005-0001.

- A local denial of service was found in the auditing subsystem which
have lead a local attacker crashing the machine. This was reported
and fixed by Redhat.

- The sendmsg / cmsg fix from the previous kernel update was faulty
on 64bit systems with 32bit compatibility layer and could lead to
32bit applications not working correctly on those 64bit systems.

- The smbfs security fixes from a before-previous kernel update were
faulty for some file write cases.

- A local denial of service with Direct I/O access to NFS file systems
could lead a local attacker to crash a machine with NFS mounts.

- grsecurity reported a signed integer problem in the SCSI ioctl
handling which had a missing boundary check.
Due to C language specifics, this evaluation was not correct and
there actually is no problem in this code.
The signed / unsigned mismatch was fixed nevertheless.

- Several more small non security problems were fixed.

NOTE: Two days ago we released the Service Pack 1 for the SUSE Linux
Enterprise Server 9. This kernel update contains fixes for the SUSE
Linux Enterprise Server 9 GA version kernel line.

A fix for the Service Pack 1 version line will be available shortly.
