Detail

Synopsis

Gentoo's GIMPS ebuilds are vulnerable to privilege escalation due to improper permissions. A local attacker could use it to gain root privileges.

Background

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

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

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.

Workaround

There is no known workaround at this time.

Resolution

All GIMPS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=sci-mathematics/gimps-28.10-r1"
