Descriptions

A vulnerability was found in systemd-resolved. This issue may allow systemd-resolved to accept records of DNSSEC-signed domains even when they have no signature, allowing man-in-the-middles (or the upstream DNS resolver) to manipulate records.

Se encontró una vulnerabilidad en systemd-resolved. Este problema puede permitir que systemd-resolved acepte registros de dominios firmados por DNSSEC incluso cuando no tienen firma, lo que permite que los intermediarios (o el solucionador de DNS ascendente) manipulen los registros.

This update for systemd fixes the following issues. Fixed man-in-the-middle due to unsigned name response in signed zone not refused when DNSSEC=yes. Unit: drop ProtectClock=yes from systemd-udevd.service. Don't mention any rpm macros inside comments, even if escaped. Skip redundant dependencies specified the LSB description that references the file name of the service itself for early boot scripts.
