From the Pardus advisory:
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-2010-2071:
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.
