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.

### Impact The REXML gem before 3.3.1 has some DoS vulnerabilities when it parses an XML that has many specific characters such as `<`, `0` and `%>`. If you need to parse untrusted XMLs, you may be impacted to these vulnerabilities. ### Patches The REXML gem 3.3.2 or later include the patches to fix these vulnerabilities. ### Workarounds Don't parse untrusted XMLs. ### References * https://github.com/ruby/rexml/security/advisories/GHSA-vg3r-rm7w-2xgh : This is a similar vulnerability * https://www.ruby-lang.org/en/news/2024/07/16/dos-rexml-cve-2024-39908/

Debian Linux Security Advisory 5730-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.

Ubuntu Security Notice 6896-2 - 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.

Ubuntu Security Notice 6895-2 - 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 6893-2 - It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when modifying certain settings values through debugfs. A privileged 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.
