Synopsis
=======
The etc2ps.sh script, included in the Netatalk package, is vulnerable
to symlink attacks, potentially allowing a local user to overwrite
arbitrary files with the rights of the user running the utility.

Background
=========
Netatalk is a kernel level implementation of the AppleTalk Protocol
Suite, which allows Unix hosts to act as file, print, and time serversfor Apple computers. It includes several script utilities, including
etc2ps.sh.

Affected packages
================
    -------------------------------------------------------------------
     Package          /  Vulnerable  /                      Unaffected
    -------------------------------------------------------------------
  1  net-fs/netatalk     < 1.6.4-r1                        >= 1.6.4-r1

Description
==========
The etc2ps.sh script creates temporary files in world-writeable
directories with predictable names.

Impact
=====
A local attacker could create symbolic links in the temporary files
directory, pointing to a valid file somewhere on the filesystem. When
etc2ps.sh is executed, this would result in the file being overwritten
with the rights of the user running the utility, which could be the
root user.

Workaround
=========
There is no known workaround at this time.

Resolution
=========
All Netatalk users should upgrade to the latest version:

    # emerge sync

    # emerge -pv ">=net-fs/netatalk-1.6.4-r1"
    # emerge ">=net-fs/netatalk-1.6.4-r1"
