Title: GIMPS: Root privilege escalation (GLSA 201709-11)
Gentoo's GIMPS ebuilds are vulnerable to privilege escalation due
to improper permissions. A local attacker could use it to gain root
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.
Vulnerable: < 28.10-r1
Unaffected: >= 28.10-r1
Architectures: All supported architectures
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.
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.
There is no known workaround at this time.
All GIMPS users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=sci-mathematics/gimps-28.10-r1"
