Pardus Linux Security Advisory 2010-94            security@pardus.org.tr
------------------------------------------------------------------------
      Date: 2010-07-08
  Severity: 4
      Type: Remote
------------------------------------------------------------------------

Summary
======
Multiple vulnerabilities have been fixed in kernel.


Description
==========
CVE-2010-1641:

The do_gfs2_set_flags function in fs/gfs2/file.c in  the  Linux  kernel
before 2.6.34-git10 does not verify the  ownership  of  a  file,  which
allows local users to bypass intended access restrictions via a SETFLAGS
ioctl request.



CVE-2010-1636:

The  btrfs_ioctl_clone function  in  fs/btrfs/ioctl.c  in  the   btrfs
functionality in the Linux kernel 2.6.29 through 2.6.32,  and  possibly
other versions, does not ensure that a cloned file descriptor has  been
opened  for reading,  which  allows  local  users  to  read  sensitive
information from a write-only file descriptor.



CVE-2010-2071:

The btrfs_xattr_set_acl function in fs/btrfs/acl.c in btrfs in the Linux
kernel 2.6.34 and earlier does not check file ownership before  setting
an ACL, which allows local users to bypass file permissions by  setting
arbitrary ACLs, as demonstrated using setfacl.



CVE-2010-2066:

If the donor file is an append-only  file,  we  should  not  allow  the
operation to proceed, lest we end up overwriting  the  contents  of  an
append-only file.


Affected packages:

  Pardus 2009:
    kernel, all before 2.6.31.13-131-46
    kernel-pae, all before 2.6.31.13-131-27



Resolution
=========
There are update(s) for kernel, kernel-pae. You  can  update  them  via
Package Manager or with a single command from console:

    pisi up kernel kernel-pae
