An issue in Gevent Gevent before version 23.9.1 allows a remote attacker to escalate privileges via a crafted script to the WSGIServer component.

MultiBit HD before 0.1.2 allows attackers to conduct bit-flipping attacks that insert unspendable Bitcoin addresses into the list that MultiBit uses to send fees to the developers. (Attackers cannot realistically steal these fees for themselves.) This occurs because there is no message authentication code (MAC).

Ftrace-based Linux loadable kernel module rootkit for Linux kernel versions 5.x and 6.x on x86_64. It hides files, hides process, hides a bind shell and reverse shell port, provides privilege escalation, and cleans up logs and bash history during installation.

A flaw was found in Red Hat Single Sign-On for OpenShift container images, which are configured with an unsecured management interface enabled. This flaw allows an attacker to use this interface to deploy malicious code and access and modify potentially sensitive information in the app server configuration.

The fix for XSA-423 added logic to Linux'es netback driver to deal with a frontend splitting a packet in a way such that not all of the headers would come in one piece. Unfortunately the logic introduced there didn't account for the extreme case of the entire packet being split into as many pieces as permitted by the protocol, yet still being smaller than the area that's specially dealt with to keep all (possible) headers together. Such an unusual packet would therefore trigger a buffer overrun in the driver.
