By Jon Munshaw.  Welcome to this week’s edition of the Threat Source newsletter.  I’ve been thinking a lot recently about the pros and cons of the way we publicize our threat research. I had a few conversations at Cisco Live with people — who are more generally IT-focused than... [[ This is only the beginning! Please visit the blog for the complete entry ]]

The heap buffer-overflow issue in Chrome for Android could be used for DoS, code execution, and more.

The heap buffer overflow issue in the browser’s WebRTC engine could allow attackers to execute arbitrary code.

Das U-Boot 2022.01 has a Buffer Overflow, a different issue than CVE-2022-30552.

Cybersecurity researchers have disclosed two unpatched security vulnerabilities in the open-source U-Boot boot loader. The issues, which were uncovered in the IP defragmentation algorithm implemented in U-Boot by NCC Group, could be abused to achieve arbitrary out-of-bounds write and denial-of-service (DoS). U-Boot is a boot loader used in Linux-based embedded systems such as ChromeOS as well as

An out-of-bounds read flaw was found in the Linux kernel’s TeleTYpe subsystem. The issue occurs in how a user triggers a race condition using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory in the flush_to_ldisc function. This flaw allows a local user to crash the system or read unauthorized random data from memory.
