Ubuntu Security Notice 6454-2 - 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 6441-3 - Ross Lagerwall discovered that the Xen netback backend driver in the Linux kernel did not properly handle certain unusual packets from a paravirtualized network frontend, leading to a buffer overflow. An attacker in a guest VM could use this to cause a denial of service or possibly execute arbitrary code. Kyle Zeng discovered that the networking stack implementation in the Linux kernel did not properly validate skb object size in certain conditions. An attacker could use this cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 6459-1 - Multiple security issues were discovered in MySQL and this update includes new upstream MySQL versions to fix these issues. MySQL has been updated to 8.0.35 in Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, Ubuntu 23.04, and Ubuntu 23.10. In addition to security fixes, the updated packages contain bug fixes, new features, and possibly incompatible changes.

Ubuntu Security Notice 6457-1 - Tavis Ormandy discovered that Node.js 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. Elison Niven discovered that Node.js 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 execute arbitrary code.

Ubuntu Security Notice 6458-1 - It was discovered that Slurm did not properly handle credential management, which could allow an unprivileged user to impersonate the SlurmUser account. An attacker could possibly use this issue to execute arbitrary code as the root user. It was discovered that Slurm did not properly handle access control when dealing with RPC traffic through PMI2 and PMIx, which could allow an unprivileged user to send data to an arbitrary unix socket in the host. An attacker could possibly use this issue to execute arbitrary code as the root user.

Ubuntu Security Notice 6455-1 - It was discovered that Exim incorrectly handled validation of user-supplied data, which could lead to memory corruption. A remote attacker could possibly use this issue to execute arbitrary code. It was discovered that Exim incorrectly handled validation of user-supplied data, which could lead to an out-of-bounds read. An attacker could possibly use this issue to expose sensitive information.

Ubuntu Security Notice 6456-1 - Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially crafted website, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information across domains, or execute arbitrary code. Kelsey Gilbert discovered that Firefox 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.

An issue was discovered in ISPConfig before 3.2.11p1. PHP code injection can be achieved in the language file editor by an admin if admin_allow_langedit is enabled.

Ubuntu Security Notice 6446-3 - Ross Lagerwall discovered that the Xen netback backend driver in the Linux kernel did not properly handle certain unusual packets from a paravirtualized network frontend, leading to a buffer overflow. An attacker in a guest VM could use this to cause a denial of service or possibly execute arbitrary code. Bien Pham discovered that the netfiler subsystem in the Linux kernel contained a race condition, leading to a use-after-free vulnerability. A local user could use this to cause a denial of service or possibly execute arbitrary code.
