∗∗∗ Forthcoming OpenSSL Releases ∗∗∗
---------------------------------------------
These releases will be made available on 28th May 2019 between approximately 1200-1600 UTC. OpenSSL 1.1.0k and 1.0.2s contain security hardening bug fixes only but do not address any CVEs. OpenSSL 1.1.1c is a bug-fix release (and contains the equivalent security hardening fixes as for 1.1.0k and 1.0.2s where relevant).

∗∗∗ Gefälschte Gewinn-SMS im Namen der Post führt in Abo-Falle ∗∗∗
---------------------------------------------
Konsument/innen erhalten eine gefälschte SMS-Nachricht im Namen der Post AG aufgrund einer angeblichen Gewinnspielteilnahme zugesandt. Wer dem Link folgt, an einer kurzen Umfrage teilnimmt und einen Gewinn auswählt, tappt in eine Abo-Falle. Es bleibt nämlich nicht bei der einmaligen Zahlung von 2 Euro für Adidas Schuhe, die nie geliefert werden, sondern es folgen laufend weitere Abbuchungen durch die ILS Company ApS.
