Synopsis ========
Gentoo's MUNGE ebuilds are vulnerable to privilege escalation due to improper permissions.
Background ==========
An authentication service for creating and validating credentials.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 sys-auth/munge < 0.5.10-r2 >= 0.5.10-r2
Description ===========
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.
Impact ======
A local attacker, who either is already MUNGE's system user or belongs to MUNGE's group, could potentially escalate privileges.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All MUNGE users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=sys-auth/munge-0.5.10-r2"
References ==========
Availability ============
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:

Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users' machines is of utmost importance to us. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at https://bugs.gentoo.org.
