<title>Netatalk: Insecure tempfile handling in etc2ps.sh</title>
|
|
<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.

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

<p>
|
|
The etc2ps.sh script creates temporary files in world-writeable directories
|
|
with predictable names.

<impact type="normal">
|
|
<p>
|
|
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>
|
|
<p>
|
|
There is no known workaround at this time.

</workaround>

<resolution>
|

<p>
|

All Netatalk users should upgrade to the latest version:

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