|
|
A stack based buffer overflow has been discovered in the
|
|
svcauth_gss_validate() function in file lib/rpc/svc_auth_gss.c when
|
|
processing an overly long string in a RPC message.
|
|
</p>

|
|
<impact type="high">
|
|
<p>
|
|
A remote attacker could send a specially crafted RPC request to an
|
|
application relying on this library, e.g NFSv4 or Kerberos
|
|
(GLSA-200709-01), resulting in the execution of arbitrary code with the
|
|
privileges of the user running the application.
|
|
</p>
|

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All librpcsecgss users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-libs/librpcsecgss-0.16"</code>
