A big promise with a big appeal. You hear that a lot in the world of cybersecurity, where you're often promised a fast, simple fix that will take care of all your cybersecurity needs, solving your security challenges in one go.  It could be an AI-based tool, a new superior management tool, or something else – and it would probably be quite effective at what it promises to do. But is it a silver

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has issued a new Binding Operational Directive (BOD) that directs federal agencies in the country to keep track of assets and vulnerabilities on their networks six months from now. To that end, Federal Civilian Executive Branch (FCEB) enterprises have been tasked with two sets of activities: Asset discovery and vulnerability

Australian telecom giant Optus on Monday confirmed that nearly 2.1 million of its current and former customers suffered a leak of their personal information and at least one form of identification number as a result of a data breach late last month.

"These attacks installed the Chopper web shell to facilitate hands-on-keyboard access, which the attackers used to perform Active Directory

It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-33655) Duoming Zhou discovered that race conditions existed in the timer handling implementation of the Linux kernel's Rose X.25 protocol layer, resulting in use-after-free vulnerabilities. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-2318) Roger Pau Monné discovered that the Xen virtual block driver in the Linux kernel did not properly initialize memory pages to be used for shared communication with the backend. A local attacker could use this to expose sensitive information (guest kernel memory). (CVE-2022-26365) Roger Pau Monné discovered that the Xen paravirtualization frontend in the Linux kernel did not properly initialize memory pages to be used for shared communication with the backend. A local attacker could use this to expose sensitive information (guest kernel memory). (CVE-2022-33740) It was discovered that the Xen paravirtualization frontend in the Linux kernel incorrectly shared unrelated data when communicating with certain backends. A local attacker could use this to cause a denial of service (guest crash) or expose sensitive information (guest kernel memory). (CVE-2022-33741, CVE-2022-33742) Jan Beulich discovered that the Xen network device frontend driver in the Linux kernel incorrectly handled socket buffers (skb) references when communicating with certain backends. A local attacker could use this to cause a denial of service (guest crash). (CVE-2022-33743) Oleksandr Tyshchenko discovered that the Xen paravirtualization platform in the Linux kernel on ARM platforms contained a race condition in certain situations. An attacker in a guest VM could use this to cause a denial of service in the host OS. (CVE-2022-33744) It was discovered that the virtio RPMSG bus driver in the Linux kernel contained a double-free vulnerability in certain error conditions. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-34494, CVE-2022-34495) Domingo Dirutigliano and Nicola Guerrera discovered that the netfilter subsystem in the Linux kernel did not properly handle rules that truncated packets below the packet header size. When such rules are in place, a remote attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-36946)

Benjamin Balder Bach discovered that Django incorrectly handled certain internationalized URLs. A remote attacker could possibly use this issue to cause Django to crash, resulting in a denial of service.

Lahav Schlesinger discovered that strongSwan incorrectly handled certain OCSP URIs and and CRL distribution points (CDP) in certificates. A remote attacker could possibly use this issue to initiate IKE_SAs and send crafted certificates that contain URIs pointing to servers under their control, which can lead to a denial-of-service attack.

It was discovered that the framebuffer driver on the Linux kernel did not verify size limits when changing font or screen size, leading to an out-of- bounds write.
