<title>Esearch: Insecure temp file handling</title>
|
|
<synopsis>
|
|
The eupdatedb utility in esearch creates a file in /tmp without first
|
|
checking for symlinks. This makes it possible for any user to create
|
|
arbitrary files.

Esearch is a replacement for the Portage command "emerge search". It
|
|
uses an index to speed up searching of the Portage tree.

|
|
The eupdatedb utility uses a temporary file (/tmp/esearchdb.py.tmp) to
|
|
indicate that the eupdatedb process is running. When run, eupdatedb
|
|
checks to see if this file exists, but it does not check to see if it
|
|
is a broken symlink. In the event that the file is a broken symlink,
|
|
the script will create the file pointed to by the symlink, instead of
|
|
printing an error and exiting.
|
|

<impact type="normal">
|
|
<p>
|
|
An attacker could create a symlink from /tmp/esearchdb.py.tmp to a
|
|
nonexistent file (such as /etc/nologin), and the file will be created
|
|
the next time esearchdb is run.

<workaround>

There is no known workaround at this time. All users should upgrade to

the latest available version of esearch.
