Dubbed "Raindrop" by Broadcom-owned Symantec, the malware joins the likes of other malicious implants such as Sunspot, Sunburst (or Solorigate), and Teardrop that were stealthily delivered to enterprise networks. --------------------------------------------- https://thehackernews.com/2021/01/researchers-discover-raindrop-4th.html ∗∗∗ Jetzt neues Passwort vergeben!

Dabei handelt es sich um zwei zunächst völlig unterschiedliche Klassen von Problemen: Buffer Overflows in der Verarbeitung von DNSSEC-Records und einen unzureichenden Schutz vor DNS-Spoofing-Angriffen. ... Dnsmasq hat die entsprechenden Lücken in Version 2.83 geschlossen. Doch in vielen Fällen dürfte es schwer sein, Updates zu installieren. Dnsmasq wird sehr häufig in Embedded-Geräten und auch auf Android-Telefonen eingesetzt - also auf den Geräten, für die es häufig keine regelmäßigen Sicherheitsupdates gibt. Die Webseite von DNSpooq listet eine ganze Reihe von betroffenen Herstellern sowie deren Security-Advisories auf, die Liste dürfte aber unvollständig sein. --------------------------------------------- https://www.golem.de/news/dnspooq-mehrere-sicherheitsluecken-in-dnsmasq-210… ∗∗∗ Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers Remote Command Execution and Denial of Service Vulnerabilities ∗∗∗ --------------------------------------------- Multiple vulnerabilities in the Universal Plug and Play (UPnP) service and the web-based management interface of Cisco Small Business RV110W, RV130, RV130W, and RV215W Routers could allow a remote attacker to execute arbitrary code or cause an affected device to restart unexpectedly.
