Ubuntu Security Notice 6879-1 - Jingzhou Fu discovered that Virtuoso Open-Source Edition incorrectly handled certain crafted SQL statements. An attacker could possibly use this issue to crash the program, resulting in a denial of service. Jingzhou Fu discovered that Virtuoso Open-Source Edition incorrectly handled certain crafted SQL statements. An attacker could possibly use this issue to crash the program, resulting in a denial of service. This issue only affects Ubuntu 22.04 LTS and Ubuntu 24.04 LTS.

Ubuntu Security Notice 6873-2 - It was discovered that the Intel Data Streaming and Intel Analytics Accelerator drivers in the Linux kernel allowed direct access to the devices for unprivileged users and virtual machines. A local attacker could use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 6870-2 - It was discovered that the Intel Data Streaming and Intel Analytics Accelerator drivers in the Linux kernel allowed direct access to the devices for unprivileged users and virtual machines. A local attacker could use this to cause a denial of service. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 6866-2 - It was discovered that the ext4 file system implementation in the Linux kernel did not properly validate data state on write operations. An attacker could use this to construct a malicious ext4 file system image that, when mounted, could cause a denial of service. It was discovered that the ATA over Ethernet driver in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6864-2 - It was discovered that the Intel Data Streaming and Intel Analytics Accelerator drivers in the Linux kernel allowed direct access to the devices for unprivileged users and virtual machines. A local attacker could use this to cause a denial of service. A security issue was discovered in the Linux kernel. An attacker could possibly use it to compromise the system.

Ubuntu Security Notice 6878-1 - Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Zheng Wang discovered that the Broadcom FullMAC WLAN driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A physically proximate attacker could possibly use this to cause a denial of service.

French cloud computing firm OVHcloud said it mitigated a record-breaking distributed denial-of-service (DDoS) attack in April 2024 that reached a packet rate of 840 million packets per second (Mpps). This is just above the previous record of 809 million Mpps reported by Akamai as targeting a large European bank in June 2020. The 840 Mpps DDoS attack is said to have been a combination of a TCP

Cybersecurity researchers have uncovered a new botnet called Zergeca that's capable of conducting distributed denial-of-service (DDoS) attacks. Written in Golang, the botnet is so named for its reference to a string named "ootheca" present in the command-and-control (C2) servers ("ootheca[.]pw" and "ootheca[.]top"). "Functionally, Zergeca is not just a typical DDoS botnet; besides supporting six
