Legislation Introduced to Make Violence Against Healthcare Workers a Federal Crime
Companion bills have recently been introduced in the House of Representatives and the Senate that seek to make violent attacks on employees of hospitals and healthcare organizations a federal crime. Data released by the U.S. Bureau of Labor Statistics in 2018 revealed that healthcare workers are five times more likely to experience violence in the workplace than workers in other industries. In 2018, healthcare workers accounted for 73% of all nonfatal workplace injuries and illnesses due to violence, and there was an increase in violent incidents during the COVID-19 pandemic. In January 2024, a poll conducted by the American College of Emergency Physicians revealed that 91% of respondents had either personally experienced violence in the workplace or were aware of a colleague who was a victim of violence in the past year. 40% of respondents said they knew of an attack on a healthcare worker in a trauma center that resulted in moderate to severe disability or death. Last year, the American College of Surgeons reported an increase in violence against surgeons. Jay J. Doucet, MD, MSc,...

High Severity Vulnerability Identified in MicroDicom DICOM Viewer
A high-severity vulnerability has been identified in the MicroDicom DICOM Viewer, a popular free-to-use software for viewing and manipulating DICOM medical images. The vulnerability can be exploited remotely in a low complexity attack, and successful exploitation can allow the execution of arbitrary code on vulnerable installations of DICOM Viewer; however, user interaction is required to exploit the vulnerability. A threat actor would need to convince a user to open a malicious DICOM file locally or visit a specially crafted malicious web page, for example, through social engineering or phishing. The vulnerability affects DICOM Viewer version 2025.2 (Build 8154) and prior versions and is tracked as CVE-2025-5943. The vulnerability is an out-of-bounds write issue, where it is possible to write to memory outside the bounds of the intended buffer and execute arbitrary code. The vulnerability has been assigned a CVSS v4 base score of 8.6 out of 10 and a CVSS v3.1 base score of 8.8 out of 10. While there have been no known cases of the vulnerability being exploited in the wild at the...
