<title>GIMPS: Root privilege escalation</title>
|
|
|
|
|
|
<synopsis>Gentoo's GIMPS ebuilds are vulnerable to privilege escalation due
|
|
|
|
|
|
to improper permissions. A local attacker could use it to gain root
|
|
|
|
|
|
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.

<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.
