David Watson discovered a vulnerability in getmail when it is
|
||
|
|
configured to run as root and deliver mail to the maildirs/mbox files
|
||
|
|
of untrusted local users. A malicious local user can then exploit a
|
||
|
|
race condition, or a similar symlink attack, and potentially cause
|
||
|
|
getmail to create or overwrite files in any directory on the system.

||

|
||
|
|
An untrusted local user could potentially create or overwrite files in
|
||
|
|
any directory on the system. This vulnerability may also be exploited
|
||
|
|
to have arbitrary commands executed as root.
|
||
|
|
</p>
|
||
|
|
</impact>
|
||
|
|
<workaround>
|
||
|
|
<p>
|
||
|
|
Do not run getmail as a privileged user; or, in version 4, use an
|
||
|
|
external MDA with explicitly configured user and group privileges.
|
||
|
|
</p>
|
||
|
|
</workaround>
|
||
|
|
<resolution>
|
||
|
|
<p>
|
||
|
|
All getmail users should upgrade to the latest version:
|
||
|
|
</p>

<code>
|

|
|
# emerge sync
|
||
|

|

# emerge -pv ">=net-mail/getmail-4.2.0"
|
||
|
|
# emerge ">=net-mail/getmail-4.2.0"</code>
