Ubuntu Security Notice 5716-2 - USN-5716-1 fixed a vulnerability in SQLite. This update provides the corresponding update for Ubuntu 14.04 ESM. It was discovered that SQLite incorrectly handled certain long string arguments. An attacker could use this issue to cause SQLite to crash, resulting in a denial of service, or possibly execute arbitrary code.

Ubuntu Security Notice 5658-3 - USN-5658-1 fixed several vulnerabilities in DHCP. This update provides the corresponding update for Ubuntu 14.04 ESM. It was discovered that DHCP incorrectly handled option reference counting. A remote attacker could possibly use this issue to cause DHCP servers to crash, resulting in a denial of service.

An issue was discovered in Appalti & Contratti 9.12.2. It allows Session Fixation. When a user logs in providing a JSESSIONID cookie that is issued by the server at the first visit, the cookie value is not updated after a successful login.

Roxy Fileman versions 1.4.6 and below remote shell upload proof of concept exploit.

Ubuntu Security Notice 5733-1 - It was discovered that FLAC was not properly performing memory management operations, which could result in a memory leak. An attacker could possibly use this issue to cause FLAC to consume resources, leading to a denial of service. This issue only affected Ubuntu 14.04 ESM, Ubuntu 16.04 ESM and Ubuntu 18.04 LTS. It was discovered that FLAC was not properly performing bounds checking operations when decoding data. If a user or automated system were tricked into processing a specially crafted file, an attacker could possibly use this issue to expose sensitive information or to cause FLAC to crash, leading to a denial of service. This issue only affected Ubuntu 14.04 ESM, Ubuntu 16.04 ESM, Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.

Ubuntu Security Notice 5729-2 - It was discovered that a race condition existed in the instruction emulator of the Linux kernel on Arm 64-bit systems. A local attacker could use this to cause a denial of service. Hsin-Wei Hung discovered that the BPF subsystem in the Linux kernel contained an out-of-bounds read vulnerability in the x86 JIT compiler. A local attacker could possibly use this to cause a denial of service or expose sensitive information.

Ubuntu Security Notice 5686-3 - USN-5686-1 fixed vulnerabilities in Git. This update provides the corresponding updates for Ubuntu 22.10. Cory Snider discovered that Git incorrectly handled certain symbolic links. An attacker could possibly use this issue to cause an unexpected behaviour.

David Bouman discovered that the netfilter subsystem in the Linux kernel did not properly validate passed user register indices. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. David Bouman and Billy Jheng Bing Jhong discovered that a race condition existed in the io_uring subsystem in the Linux kernel, leading to a use- after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. Various other issues were also addressed.

Ubuntu Security Notice 5728-2 - Jann Horn discovered that the Linux kernel did not properly track memory allocations for anonymous VMA mappings in some situations, leading to potential data structure reuse. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that a race condition existed in the memory address space accounting implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5727-2 - It was discovered that a race condition existed in the instruction emulator of the Linux kernel on Arm 64-bit systems. A local attacker could use this to cause a denial of service. It was discovered that the KVM implementation in the Linux kernel did not properly handle virtual CPUs without APICs in certain situations. A local attacker could possibly use this to cause a denial of service.
