HIGH 7.0WATCHLISTDOWNGRADE

CVE-2019-11675 is a high-severity flaw (CVSS 7.0) affecting groonga-httpd. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The groonga-httpd package 6.1.5-1 for Debian sets the /var/log/groonga ownership to the groonga account, which might let local users obtain root access because of unsafe interaction with logrotate. For example, an attacker can exploit a race condition to insert a symlink from /var/log/groonga/httpd to /etc/bash_completion.d. NOTE: this is an issue in the Debian packaging of the Groonga HTTP server.

Affected: 6.5.1-1

Fixed in: no fixed release known

Safe to downgrade to: a release before 6.5.1-1

apt-cache policy groonga-httpd || rpm -q groonga-httpd || groonga-httpd --version

2. No fixed release: DOWNGRADE to a release before 6.5.1-1 (Debian / Ubuntu)

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
