Ubuntu Security Notice 6909-2 - USN-6909-1 fixed several vulnerabilities in Bind. This update provides the corresponding update for Ubuntu 18.04 LTS. Toshifumi Sakaguchi discovered that Bind incorrectly handled having a very large number of RRs existing at the same time. A remote attacker could possibly use this issue to cause Bind to consume resources, leading to a denial of service.

Ubuntu Security Notice 6926-2 - 黄思聪 discovered that the NFC Controller Interface implementation in the Linux kernel did not properly handle certain memory allocation failure conditions, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service. 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.

Ubuntu Security Notice 6922-2 - 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. Chenyuan Yang discovered that the Unsorted Block Images flash device volume management subsystem did not properly validate logical eraseblock sizes in certain situations. An attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice 6936-1 - It was discovered that Apache Commons Collections allowed serialization support for unsafe classes by default. A remote attacker could possibly use this issue to execute arbitrary code.

Ubuntu Security Notice 6941-1 - It was discovered that the Python ipaddress module contained incorrect information about which IP address ranges were considered “private” or “globally reachable”. This could possibly result in applications applying incorrect security policies.

Ubuntu Security Notice 6934-1 - Multiple security issues were discovered in MySQL and this update includes new upstream MySQL versions to fix these issues. MySQL has been updated to 8.0.39 in Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 24.04 LTS. In addition to security fixes, the updated packages contain bug fixes, new features, and possibly incompatible changes.

Ubuntu Security Notice 6932-1 - It was discovered that the Hotspot component of OpenJDK 21 was not properly performing bounds when handling certain UTF-8 strings, which could lead to a buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. It was discovered that the Hotspot component of OpenJDK 21 could be made to run into an infinite loop. If an automated system were tricked into processing excessively large symbols, an attacker could possibly use this issue to cause a denial of service.

Ubuntu Security Notice 6931-1 - It was discovered that the Hotspot component of OpenJDK 17 was not properly performing bounds when handling certain UTF-8 strings, which could lead to a buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. It was discovered that the Hotspot component of OpenJDK 17 could be made to run into an infinite loop. If an automated system were tricked into processing excessively large symbols, an attacker could possibly use this issue to cause a denial of service.

Ubuntu Security Notice 6930-1 - It was discovered that the Hotspot component of OpenJDK 11 was not properly performing bounds when handling certain UTF-8 strings, which could lead to a buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. It was discovered that the Hotspot component of OpenJDK 11 could be made to run into an infinite loop. If an automated system were tricked into processing excessively large symbols, an attacker could possibly use this issue to cause a denial of service.

Ubuntu Security Notice 6929-1 - It was discovered that the Hotspot component of OpenJDK 8 was not properly performing bounds when handling certain UTF-8 strings, which could lead to a buffer overflow. An attacker could possibly use this issue to cause a denial of service or execute arbitrary code. It was discovered that the Hotspot component of OpenJDK 8 could be made to run into an infinite loop. If an automated system were tricked into processing excessively large symbols, an attacker could possibly use this issue to cause a denial of service.
