SuSE 11 Security Update : Linux kernel (SAT Patch Numbers 713 / 715 / 716)

This script is Copyright (C) 2009-2016 Tenable Network Security, Inc.

Synopsis :

The remote SuSE 11 host is missing one or more security updates.

Description :

This Linux kernel update for SUSE Linux Enterprise 11 fixes lots of
bugs and some security issues.

The kernel was also updated to the stable release.

- nfsd in the Linux kernel does not drop the CAP_MKNOD
capability before handling a user request in a thread,
which allows local users to create device nodes, as
demonstrated on a filesystem that has been exported with
the root_squash option. (CVE-2009-1072)

- The sock_getsockopt function in net/core/sock.c in the
Linux kernel does not initialize a certain structure
member, which allows local users to obtain potentially
sensitive information from kernel memory via an
SO_BSDCOMPAT getsockopt request. The fix for this was
incomplete. (CVE-2009-0676)

- The __secure_computing function in kernel/seccomp.c in
the seccomp subsystem in the Linux kernel on the x86_64
platform, when CONFIG_SECCOMP is enabled, does not
properly handle (1) a 32-bit process making a 64-bit
syscall or (2) a 64-bit process making a 32-bit syscall,
which allows local users to bypass intended access
restrictions via crafted syscalls that are
misinterpreted as (a) stat or (b) chmod. (CVE-2009-0835)
