Detail

Synopsis

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

Background

An authentication service for creating and validating credentials.

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"
