Ubuntu Security Notice 5937-1 - It was discovered that Opusfile was not properly validating pointer arguments in some of its functions, which could lead to a NULL pointer dereference. An attacker could possibly use this issue to cause a denial of service or have other unspecified impacts.

Ubuntu Security Notice 5932-1 - It was discovered that Sofia-SIP incorrectly handled specially crafted SDP packets. A remote attacker could use this issue to cause applications using Sofia-SIP to crash, leading to a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 ESM, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS and Ubuntu 22.04 LTS. It was discovered that Sofia-SIP incorrectly handled specially crafted UDP packets. A remote attacker could use this issue to cause applications using Sofia-SIP to crash, leading to a denial of service.

Ubuntu Security Notice 5933-1 - Francisco Falcon discovered that Libtpms did not properly manage memory when performing certain cryptographic operations. An attacker could possibly use this issue to cause a denial of service, or possibly execute arbitrary code. It was discovered that Libtpms did not properly manage memory when handling certain commands. An attacker could possibly use this issue to cause a denial of service.

Ubuntu Security Notice 5935-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Davide Ornaghi discovered that the netfilter subsystem in the Linux kernel did not properly handle VLAN headers in some situations. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Kyle Zeng discovered that the sysctl implementation in the Linux kernel contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. Tamás Koczka discovered that the Bluetooth L2CAP handshake implementation in the Linux kernel contained multiple use-after-free vulnerabilities. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. It was discovered that the NFSD implementation in the Linux kernel did not properly handle some RPC messages, leading to a buffer overflow. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.

Ubuntu Security Notice 5934-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the NVMe driver in the Linux kernel did not properly handle reset events in some situations. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 5931-1 - It was discovered that Python incorrectly handled certain inputs. If a user or an automated system were tricked into running a specially crafted input, a remote attacker could possibly use this issue to execute arbitrary code.

Ubuntu Security Notice 5930-1 - It was discovered that Python incorrectly handled certain inputs. If a user or an automated system were tricked into running a specially crafted input, a remote attacker could possibly use this issue to execute arbitrary code.

Ubuntu Security Notice 5929-1 - It was discovered that the Upper Level Protocol subsystem in the Linux kernel did not properly handle sockets entering the LISTEN state in certain protocols, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. Davide Ornaghi discovered that the netfilter subsystem in the Linux kernel did not properly handle VLAN headers in some situations. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

Ubuntu Security Notice 5928-1 - It was discovered that systemd did not properly validate the time and accuracy values provided to the format_timespan function. An attacker could possibly use this issue to cause a buffer overrun, leading to a denial of service attack. This issue only affected Ubuntu 14.04 ESM, Ubuntu 16.04 ESM, Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. It was discovered that systemd did not properly manage the fs.suid_dumpable kernel configurations. A local attacker could possibly use this issue to expose sensitive information. This issue only affected Ubuntu 20.04 LTS, Ubuntu 22.04 LTS, and Ubuntu 22.10.
