A flaw was found in the QEMU implementation of VMWare's paravirtual RDMA device. This flaw allows a crafted guest driver to allocate and initialize a huge number of page tables to be used as a ring of descriptors for CQ and async events, potentially leading to an out-of-bounds read and crash of QEMU.

Nearly 20% of the zero-day flaws that attackers exploited in 2022 were in network, security, and IT management products, Mandiant says.

The zero-day exploitation of a now-patched medium-security flaw in the Fortinet FortiOS operating system has been linked to a suspected Chinese hacking group. Threat intelligence firm Mandiant, which made the attribution, said the activity cluster is part of a broader campaign designed to deploy backdoors onto Fortinet and VMware solutions and maintain persistent access to victim environments.

By Deeba Ahmed According to researchers, multiple Fortinet products were impacted by this vulnerability, including FortiManager, FortiGate, and FortiAnalyzer. This is a post from HackRead.com Read the original post: Chinese Hackers Exploiting 0-day Vulnerability in Fortinet Products

Hornetsecurity research highlights that more than 1 in 4 companies have fallen victim to ransomware attacks, with 14.1% losing data and 6.6% paying a ransom.

Ubuntu Security Notice 5951-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the NVMe driver in the Linux kernel did not properly handle reset events in some situations. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 5940-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability.

It was discovered that the NVMe driver in the Linux kernel did not properly handle reset events in some situations. A local attacker could use this to cause a denial of service.

Docker Desktop before 4.17.0 allows an attacker to execute an arbitrary command inside a Dev Environments container during initialization by tricking an user to open a crafted malicious docker-desktop:// URL.

Ubuntu Security Notice 5939-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the NVMe driver in the Linux kernel did not properly handle reset events in some situations. A local attacker could use this to cause a denial of service.

More than two years after a major takedown by law enforcement, the threat group is once again proving just how impervious it is against disruption attempts.
