|
|
Alin Rad Pop (Secunia Research) discovered a boundary checking error in
|
|
the send_mailslot() function which could lead to a stack-based buffer
|
|
overflow.

|
<impact type="high">
|
|
<p>
|
|
A remote attacker could send a specially crafted "SAMLOGON" domain
|
|
logon packet, possibly leading to the execution of arbitrary code with
|
|
elevated privileges. Note that this vulnerability is exploitable only
|
|
when domain logon support is enabled in Samba, which is not the case in
|
|
Gentoo's default configuration.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
Disable domain logon in Samba by setting "<i>domain logons = no</i>" in
|
|
the "global" section of your smb.conf and restart Samba.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Samba users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-fs/samba-3.0.28"</code>
|
|
</resolution>
