As the travel industry rebounds post-pandemic, it is increasingly targeted by automated threats, with the sector experiencing nearly 21% of all bot attack requests last year. That’s according to research from Imperva, a Thales company. In their 2024 Bad Bot Report, Imperva finds that bad bots accounted for 44.5% of the industry’s web traffic in 2023—a significant jump from 37.4% in 2022.

Debian Linux Security Advisory 5731-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

It was discovered that the ATA over Ethernet (AoE) 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. It was discovered that the netfilter connection tracker for netlink in the Linux kernel did not properly perform reference counting in some error conditions. A local attacker could possibly use this to cause a denial of service (memory exhaustion). Various other issues were also addressed.

Red Hat Security Advisory 2024-4591-03 - Updated images that include numerous enhancements, security, and bug fixes are now available for Red Hat OpenShift Data Foundation 4.16.0 on Red Hat Enterprise Linux 9. Issues addressed include denial of service, memory leak, and resource exhaustion vulnerabilities.

Ubuntu Security Notice 6896-3 - 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. It was discovered that the Atheros 802.11ac wireless driver did not properly validate certain data structures, leading to a NULL pointer dereference. An attacker could possibly use this to cause a denial of service.

Red Hat Security Advisory 2024-4576-03 - An update for nghttp2 is now available for Red Hat Enterprise Linux 8.2 Advanced Update Support. Issues addressed include a denial of service vulnerability.

Ubuntu Security Notice 6900-1 - 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. It was discovered that the HugeTLB file system component of the Linux Kernel contained a NULL pointer dereference vulnerability. A privileged attacker could possibly use this to to cause a denial of service.

Ubuntu Security Notice 6898-2 - 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. Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service.

In Eclipse Parsson before 1.0.4 and 1.1.3, a document with a large depth of nested objects can allow an attacker to cause a Java stack overflow exception and denial of service. Eclipse Parsson allows processing (e.g. parse, generate, transform and query) JSON documents.

Russian threat actor FIN7 has shifted gears multiple times in recent years, focusing now on helping ransomware groups be even more covertly effective.
