Ubuntu Security Notice 6465-3 - Yu Hao and Weiteng Chen discovered that the Bluetooth HCI UART driver in the Linux kernel contained a race condition, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service. Lin Ma discovered that the Netlink Transformation subsystem in the Linux kernel contained a null pointer dereference vulnerability in some situations. A local privileged attacker could use this to cause a denial of service.

Ubuntu Security Notice 6462-2 - Seth Jenkins discovered that the Linux kernel did not properly perform address randomization for a per-cpu memory management structure. A local attacker could use this to expose sensitive information or in conjunction with another kernel vulnerability. Yu Hao and Weiteng Chen discovered that the Bluetooth HCI UART driver in the Linux kernel contained a race condition, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service.

Buffer Overflow vulnerability in free5gc 3.3.0, UPF 1.2.0, and SMF 1.2.0 allows attackers to cause a denial of service via crafted PFCP messages.

Ubuntu Security Notice 6473-1 - It was discovered that urllib3 didn't strip HTTP Authorization header on cross-origin redirects. A remote attacker could possibly use this issue to obtain sensitive information. This issue only affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. It was discovered that urllib3 didn't strip HTTP Cookie header on cross-origin redirects. A remote attacker could possibly use this issue to obtain sensitive information.

Ubuntu Security Notice 6470-1 - It was discovered that Axis incorrectly handled certain inputs. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to cause a denial of service or execute arbitrary code.

Ubuntu Security Notice 6467-2 - USN-6467-1 fixed a vulnerability in Kerberos. This update provides the corresponding update for Ubuntu 20.04 LTS, Ubuntu 22.04 LTS and Ubuntu 23.04. Robert Morris discovered that Kerberos did not properly handle memory access when processing RPC data through kadmind, which could lead to the freeing of uninitialized memory. An authenticated remote attacker could possibly use this issue to cause kadmind to crash, resulting in a denial of service.

Ubuntu Security Notice 6469-1 - Ashley Newson discovered that xrdp incorrectly handled memory when processing certain incoming connections. An attacker could possibly use this issue to cause a denial of service or arbitrary code execution.

Ubuntu Security Notice 6468-1 - Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code. Kelsey Gilbert discovered that Thunderbird did not properly manage certain browser prompts and dialogs due to an insufficient activation-delay. An attacker could potentially exploit this issue to perform clickjacking.

Ubuntu Security Notice 6454-4 - Kyle Zeng discovered that the netfilter subsystem in the Linux kernel contained a race condition in IP set operations in certain situations. A local attacker could use this to cause a denial of service. Alex Birnberg discovered that the netfilter subsystem in the Linux kernel did not properly validate register length, leading to an out-of-bounds write vulnerability. A local attacker could possibly use this to cause a denial of service.

Ubuntu Security Notice 6465-2 - Yu Hao and Weiteng Chen discovered that the Bluetooth HCI UART driver in the Linux kernel contained a race condition, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service. Lin Ma discovered that the Netlink Transformation subsystem in the Linux kernel contained a null pointer dereference vulnerability in some situations. A local privileged attacker could use this to cause a denial of service.
