Besonders kritisch ist eine Buffer Overflow Schwachstelle in der SMTP-Implementierung, CVE-2023-42115, die einer entfernten, unauthorisierten angreifenden Person gegebenenfalls das Ausführen von Code mit Rechten des Service Accounts, mit dem Exim betrieben wird, ermöglicht.

Dieser Text steht in einer SMS, die derzeit massenhaft von Kriminellen verschickt wird. Besonders perfid: In der SMS werden auch die Namen der angeblichen Gewinner:innen genannt.

In the first two weeks of September, we saw 5,440 of these attacks. Hackers are using Dropbox to create fake login pages that eventually lead to a credential harvesting page. It’s yet another example of how hackers are utilizing legitimate services in what we call BEC 3.0 attacks. Business Email Compromise 3.0 attacks refer to the usage of legitimate sites—like Dropbox—to send and host phishing material. --------------------------------------------- https://blog.checkpoint.com/harmony-email/phishing-via-dropbox/ ∗∗∗ Analysis of Time-to-Exploit Trends: 2021-2022 ∗∗∗ --------------------------------------------- Mandiant Intelligence analyzed 246 vulnerabilities that were exploited between 2021 and 2022. Sixty-two percent (153) of the vulnerabilities were first exploited as zero-day vulnerabilities. The number of exploited vulnerabilities each year continues to increase, while the overall times-to-exploit (TTEs) we are seeing are decreasing. Exploitation of a vulnerability is most likely to occur before the end of the first month following the release of a patch. --------------------------------------------- https://www.mandiant.com/resources/blog/time-to-exploit-trends-2021-2022 ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Friday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (firefox-esr, jetty9, and vim), Gentoo (Fish, GMP, libarchive, libsndfile, Pacemaker, and sudo), Oracle (nodejs:16 and nodejs:18), Red Hat (virt:av and virt-devel:av), Slackware (mozilla), SUSE (chromium, firefox, Golang Prometheus, iperf, libqb, and xen), and Ubuntu (linux-raspi). --------------------------------------------- https://lwn.net/Articles/945965/ ∗∗∗ Security Vulnerability fixed in Firefox 118.0.1, Firefox ESR 115.3.1, Firefox for Android 118.1.0, Firefox Focus for Android 118.1.0, and Thunderbird 115.3.1. ∗∗∗ --------------------------------------------- CVE-2023-5217: Heap buffer overflow in libvpx Specific handling of an attacker-controlled VP8 media stream could lead to a heap buffer overflow in the content process.
