The nginx package before 1.6.2-5+deb8u3 on Debian jessie, the nginx packages before 1.4.6-1ubuntu3.6 on Ubuntu 14.04 LTS, before 1.10.0-0ubuntu0.16.04.3 on Ubuntu 16.04 LTS, and before 1.10.1-0ubuntu1.1 on Ubuntu 16.10, and the nginx ebuild before 1.10.2-r3 on Gentoo allow local users with access to the web server user account to gain root privileges via a symlink attack on the error log.

Security readout for executives and security teams

CVE-2016-1247 lets someone who already controls or can access the nginx web server user account escalate to root on affected Debian, Ubuntu, or Gentoo packages. This is not a remote break-in by itself, but it can turn a limited server compromise into full system control. Exposure is most likely on legacy Linux hosts running old distro-packaged nginx from Debian Jessie, Ubuntu 14.04/16.04/16.10, or Gentoo before the named fixed ebuild. Internet-facing nginx alone is not sufficient; the attacker needs local access as the web server user. Treat this as high priority for legacy web infrastructure. It is a privilege-escalation weakness, so it matters most when paired with an initial foothold. Patch or retire affected packages before accepting residual risk. Mitigation focus: Upgrade Debian Jessie nginx to 1.6.2-5+deb8u3 or later.; Upgrade affected Ubuntu releases to the fixed nginx packages in USN-3114-1.; Upgrade Gentoo nginx ebuild to 1.10.2-r3 or later..
