Gentoo Linux Security Advisory

Title: MCollective: Remote Code Execution (GLSA 201709-01)
Severity: normal
Exploitable: remote
Date: 2017-09-04
Bug(s): #624704
ID: 201709-01


A vulnerability in MCollective might allow remote attackers to
execute arbitrary code.


MCollective is a framework to build server orchestration or parallel job
execution systems.

Affected Packages

Package: app-admin/mcollective
Vulnerable: < 2.11.0
Unaffected: >= 2.11.0
Architectures: All supported architectures


A vulnerability was discovered in MCollective which allowed for
deserialized YAML from agents without calling safe_load. This allows the
potential for arbitrary code execution on the server.


A remote attacker could possibly execute arbitrary code with the
privileges of the process or cause a Denial of Service condition.


There is no known workaround at this time.


All MCollective users should upgrade to the latest version:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=app-admin/mcollective-2.11.0"
