GLSA-201611-10 : libuv: Privilege escalation

Critical Nessus Plugin ID 94936


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-201611-10 (libuv: Privilege escalation)

It was discovered that libuv does not call setgroups before calling setuid/setgid. If this is not called, then even though the uid has been dropped, there may still be groups associated that permit superuser privileges.
Impact :

Context-dependent attackers could escalate privileges via unspecified vectors.
Workaround :

There is no known workaround at this time.


All libuv users should upgrade to the latest version:
# emerge --sync # emerge --ask --verbose --oneshot '>=dev-libs/libuv-1.4.2'
