MEDIUM

The zmq3 input and output modules in rsyslog before 8.28.0 interpreted description fields as format strings, possibly allowing a format string attack with unspecified impact.

Weakness

The product uses a function that accepts a format string as an argument, but the format string originates from an external source.

Name Vendor Start Version End Version
Rsyslog Rsyslog * 8.27.0 (including)
