Gentoo Linux Security Advisory

Title: MUNGE: Privilege escalation (GLSA 201706-01)
Severity: high
Exploitable: local
Date: 2017-06-06
Bug(s): #602596
ID: 201706-01


Gentoo's MUNGE ebuilds are vulnerable to privilege escalation due
to improper permissions.


An authentication service for creating and validating credentials.

Affected Packages

Package: sys-auth/munge
Vulnerable: < 0.5.10-r2
Unaffected: >= 0.5.10-r2
Architectures: All supported architectures


It was discovered that Gentoo’s default MUNGE installation suffered
from a privilege escalation vulnerability (munge user to root) due to
improper permissions and a runscript which called chown() on a user
controlled file.


A local attacker, who either is already MUNGE’s system user or belongs
to MUNGE’s group, could potentially escalate privileges.


There is no known workaround at this time.


All MUNGE users should upgrade to the latest version:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=sys-auth/munge-0.5.10-r2"
