<title>GIMPS: Root privilege escalation</title>
|
||
<synopsis>Gentoo's GIMPS ebuilds are vulnerable to privilege escalation due
|
||

|
||
privileges.

<p>GIMPS, the Great Internet Mersenne Prime Search, is a software capable
|
||
of find Mersenne Primes, which are used in cryptography. GIMPS is also
|
||
used for hardware testing.

<description>
|
||
<p>It was discovered that Gentoo’s default GIMPS installation suffered
|
||
from a privilege escalation vulnerability in the init script. This script
|
||
calls an unsafe “chown -R” command in checkconfig() function.

<impact type="high">
|
||
<p>A local attacker who does not belong to the root group, but has the
|
||
ability to modify the /var/lib/gimps directory can escalate privileges to
|
||
the root group.
|
||
</p>
|

</impact>
|
||
<workaround>
|
||
<p>There is no known workaround at this time.</p>
|
||
</workaround>
|
||
<resolution>
|
||
<p>All GIMPS users should upgrade to the latest version:</p>
