GLSA-201709-01 : MCollective: Remote Code Execution
High Nessus Plugin ID 102942
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201709-01 (MCollective: Remote Code Execution)
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.
SolutionAll MCollective users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-admin/mcollective-2.11.0'
